That deleted file can live again

The mysteries of 'Previous Versions' in Windows 7

I just deleted a document and photo I desperately need. And I've rebooted since so they are not in the Recycle Bin. Can I get them back?

Who just said "No"?

That ain't so. If you are using Windows 7 and had read this article, the answer is almost certainly "Yes!"

There's a thing that Microsoft generally doesn't say much about, called "Previous versions", or, in technical circles it’s known as “shadow copies”.

And there may be a reason they say little, although that is not a reason why you should not add it to your backup arsenal. It is part of the system restore setup and system restore has an annoying habit of occasionally switching itself off. So every now and again, especially after any system changes, just check the settings detailed below to make sure everything is still as it should be.

First click on your start icon, then right click on Computer and select Properties. In the left-hand pane select System protection (you may be prompted for administrator permission) and then click on the drive where you keep your data files and then click on the Configure button. To turn on the ability to restore previous versions click the item which states "Restore system settings and previous versions of files". Then click OK.

This will create backups of changed files on that disk whenever there is a system restore point created. That will usually be once a day or when you install a program or when you tell the system to do so.

If you only have one drive then this setting will be turned on by default but there is advice around which tells users to turn off system restore for drives other than C:

What is the downside of having this setting turned on? It takes space and on a slow computer it can slow things at critical times but on the whole Windows 7 handles system tasks, even indexing, far better than earlier forms of Windows. Basically if you can use Win7 efficiently on your computer you will not notice anything extra going on.

The amount of extra space used is controllable from the dialog box mentioned above using a slider. As you increase the percentage used, you will also have bigger backups (and this is not a substitute for regular backups). But space, in the terms of bigger drives is now cheaper than it has ever been. I now regard a 500GB drive as an annual running expense.

In future when you right-click on a file or folder you will see an option to "Restore previous versions" and that will give you a dialog listing all the previous versions available. Select one.

If the file you want has been deleted, then right-click the folder it was in and select "Restore previous versions" and you will get the choice of previous versions of the folder. Double-click a version of the folder which would have contained the file. You will not want to restore the whole lot but you can select an individual file and drag it to another location, such as the desktop.

If you can't remember the name of the file, you can use the search box or select another view of the folder such as by date. To avoid confusion the OS adds a timestamp to the name if it is a previous version.

And if you double-click a previous version of a file it will open in whatever the default editing program is and you can edit it and resave to wherever you want ... or just abandon it if it is not what you want. You cannot just save it back to the previous-version folder, which makes sense if you think about it.

There are some known problems between System restore and Norton's "Product tamper protection" but they mainly interfere with full restoration rather than single file restore. However turning off system restore is one of the common actions of malware so if you think you may have been attacked, check the settings.

An easy way to check the settings is to create a new shortcut on your desktop. Right click any open space on the desktop and click on New and then on Shortcut. In the dialog which opens type in the following:
control.exe sysdm.cpl,@0,4

Now click Next and give the shortcut a name. I suggest: Check system restore

Clicking on that shortcut will open the box which shows what disks have system restore switched on and in the bottom right is a button to create a new system restore point.

System restore only works with disks formatted as NTFS, not FAT32, disks must be larger than 1GB and must have at least 300MB of free space. As new restore points with these shadow copies are created so the existing oldest ones will be deleted. They are temporary. For real security you still need a full backup system in place.

The biggest gotcha is that if you have a dual boot system, then starting another version of Windows will delete any restore points created by the previously running version of Windows. Going back to Win7 should start the creation of restore points again but the old ones will be gone. Similarly, using Disk Cleanup to remove old restore points will also remove the previous versions of files.

The methods described here will also work in the Business and Ultimate versions of Vista but they apply to all versions of Windows 7. The technology on which it is based has been part of NTFS formatting and Windows Server operating systems since 2003. That may help explain why, in larger organisations, the individual right to turn this service on may be restricted.

How easily things can go wrong

(or how a simple OS update lost both sound and email!)

My problems started because I decided to install the Windows 7 service pack and is a typical mess caused by not realising all that was going wrong and getting in an increasing mess as more things went wrong as a result.

Because installing SP1 left me with speakers that were not working I got into a situation where I could not get my email. As ridiculous as that may seem, it was quite logical at the time... Here's the sequence:

1. Install SP1 via Windows Update. All appears to go well.
2. Open a YouTube video and can hear no sound. Check speakers and though Windows tell me they are working and green bars go up and down on the test in Control Panel, no sound comes out. Check that I have not set the speakers to mute.
3. I have a cloned hard disk that I made only the previous weekend so I decide to pull out the faulty drive and slot in the previous, pre-SP1 drive. Before I do that I realize I must copy the important constantly updated files to a USB stick: MozBackup copies the necessary files for Firefox and Thunderbird; I copy the data file for KeePass and the couple of text files I was working on.
4. I boot to my desktop as it was a week ago and all looks good, and I restore the files from the USB stick.
5. Thunderbird tells me it can't connect to my main mail server and as I look down the left-hand panel I realise it has gone back in time; there's mail for a domain I let expire six months ago, and some mail addresses I set up several months ago are not there.
6. I find via Google where Thunderbird keeps its profiles and go into my Acronis backup to copy the files from that backup. But when started Thunderbird shows the same ancient setup.
7. I sleep on the problem and next morning do some more Googling. It seems that Thunderbird profiles can be in two places under Win7 and this has been causing confusion for some users. I'm now among those. The profile in Vista was usually under the User folder tree going into the Local branch. But in Windows 7 it can be found in both the Local branch and the Roaming branch.
8. MozBackup had copied and restored the wrong Profiles folder. So I copied the Acronis backup files for both and at last Thunderbird opened with the right look. But missing the mail I downloaded after doing that backup. Of course immediately I opened Thunderbird it started downloading the overnight mail, quite a lot of it.
9. Fortunately I remembered to add an ".old" to the profiles folder before restoring the right one, and I can remember a couple of the emails lost in the interregnum so there is a good change they are in the ".old" folder somewhere and Thunderbird does store its mail in text files so all is not lost, just well hidden.
10. I still have not reinstalled SP1, so the job which started all this has still not been done. But I have found that there is an updated version of MozBackup. Mine dates to before the latest release version 1.4.10 from December 13, 2009, (which added support for Thunderbird 3) and there is a beta version of 1.5 dated March 7, 2011.

I have also found that MozBackup files are just Zip files, so, if you change the extension to Zip, you can look inside them and be selective. It may seem paranoid but I have also started to back up the mail files (now I know which are the right ones to back up) every four hours.

Lesson learned: no matter how well prepared you think you are, you can still get caught.

Windows 7: should it be Windows Silver?

November 1985 saw Windows first shipped in the USA and not long afterwards in Australia. So I wonder why Windows 7 wasn't called Windows Silver?

I can still see quite vividly that MSDOS screen in front of me at the newspaper in the small High Country town of Myrtleford that required me to click on a file entry to start the runtime version of Windows which then started the desktop publishing program PageMaker.

I'd already used the same program with Apple Macintosh in Western Australia but a PC was half the cost. And had used Xerox Ventura on a PC with the GEM "graphic environment management" system on top of DR (Digital Research) DOS, but Windows was still a massive advance.

Businesses weren't buying Windows because they wanted to but because it enabled the program they needed to run. Even the most hard hearted accountant could see that new equipment was worth buying when it would pay its full capital and running costs in less than six months compared to how the job had been done before.

The hardest job, a year or two later, was persuading newspapers in the bush that they really needed a network to transfer files, and that "sneaker net" with a shoebox of 5.25" disks had had its day.

Software that refuses to die

How many software programs from 1994 are you still using?

When I upgraded to Windows 7 and chose the 64-bit version, I expected to say goodbye to some of the pieces of software that I've used for many years.

But my barcode creation software, UPCTools, bought in 1994, refuses to die...it just keeps on working, now with its fifth operating system since it first ran in Windows 95 (or was it Windows 3.1?).

Admittedly it now runs in XP Mode, but I can select it from the Start menu of Windows 7, and then just use the UPC Tools menu item "copy" to copy the result in to InDesign (which was no more than a twinkle in the eye of some of the software people at Aldus when this software was written by Jerry Whiting at Azalea Software). The barcode fonts, which were in Type 1 Postscript format, installed in the Windows 7 font folder by just dragging them in en masse. When viewed now within InDesign those fonts show up as just one font with eight styles (to suit three inkspread requirements plus half height versions. 

Yes that is Windows 7 and the software running does say Copyright 1994. Some software was written with the future in mind!

Incidentally, to get software that runs in the XP virtual environment to show up in the Start menu of Windows 7 you have to put a shortcut in the "All Users" subfolder of the Start menu in XP and then reboot your PC. It took me a while to work that one out.

Of course I'm not suggesting you should buy the 1994 version of UPCTools but if you are looking for barcode software that will work in to the next decade, You'll find lots of info about barcodes in general at http://www.azalea.com/FAQ/

Overall, I'm happy with the decision to upgrade and the computer with its extra memory is performing well -- not a BSOD since the upgrade, though I was previously thinking it had to be replaced.

I clone: it's the easy way back after a crash

The ultimate problem on a PC. It just would not boot up. The BIOS was trying to boot from the second hard drive and could not find the first. When I disabled the second hard drive the BIOS could not find a drive at all.

Removing the tray and then the drive from the tray I could feel it spinning but there was no sign of recognition even from my SATA docking station.

This was the disaster I knew would come and fortunately I was prepared.

My hard drives are mounted in removable trays, so I could easily swap from Win 7 to my XP drive, and that booted perfectly, proving, if I still needed proof, that it was a problem with the drive and nothing else.

But I had an easy way back to business. A month ago I had cloned my main drive using software called HDclone from Miray Software in Germany.

All I had to do was replace the faulty drive in the removable tray with the cloned one...that means loosening the tray cover, sliding that off then undoing four screws, replacing the drive, doing up the screws, sliding on and tightening the cover (one screw) and sliding it into the caddy. That takes about three minutes.

Reboot and there is my OS as it was a month ago. Copy back some files from the usual weekly backup via DriveImage (OK that software is ancient and I'll go for TrueImage when the Win7 version of that is out next month, but the old one still works perfectly) and the past day or so's email and Firefox history plus the password safe data from my thumbdrive (thanks to MozBackup).

I've since cloned the drive again and updated the cloned copy of my XP system. That takes time, but not when I have to be present. The PC will chug away for the 5 or 6 hours the cloning process takes.

The Mira website states that the latest version can create cloned drives even from within Windows but I'm currently using a bootable CD made by copying their .iso file to a CD-R. And the paid versions claim to work at twice the speed, and to be able to clone partitions as well as a full drive.

Even so, the company suggests that, to prove that the software will work on your system, you first download the free version and create a cloned drive. The appeal of then being able to do it in half the time will woo most users. The Basic edition as a download costs about US$25 (they price in Euros).

As I said, the software will work within Windows but as a self-booting CD it will copy just about any drive with any OS to any other drive which is at least the same size. And since the downloaded zip file includes an .iso file, Mac and Linux users should be able to create the bootable CD.

I'm not making any special claims for them, more for cloning as an adjunct to other backup systems. There are at least five other ways to clone a drive. See this page at Downloadquad

This was the second cloning application I tried and it did all that I needed, and simply, so I've stuck with it.

Oh yes, unless you want to read the manual, have one of those (usually green) converter plugs ready to put your mouse in via the PS/2 port instead of USB, though Mira may well have solved that with the new version that I'll download shortly.

Next time someone asks if you backup you can then say "I clone".

What happened to the failed drive? It was out of warranty with the dealer I bought it from, well over 12 months, but he suggested I look at the drive maker's website. That was Seagate. They have a page to enter the model and serial numbers and if it is within 5 years of manufacture, they replace it. I got a return number, sent it off and within two weeks a replacement came back. Only cost was one-way freight to get it to their depot.

PageMaker works in Windows 7

It just needed the courage to do it: I've installed PageMaker 7 into Windows 7 and it is working with none of the problems which made me abandon a straight installation of PageMaker in XP and go for installing it within Virtual PC using Win98.

The only "problem" is the aparent slowness of loading multiple fonts in Windows 7 though I've just been told that you can just put all the .pfm and .pfb files into a new folder and drag the pfm files into the Windows font folder or go for the slow way with the additional possibility of selecting a well hidden option to keep the new fonts where they are.

But, contrary to some comments I found on the Internet, postscript fonts work fine with Windows 7. Also, when opening some files within PageMaker and getting the expected missing font dialog, I was able to select equivalent OpenType fonts and they seem to have worked -- i.e. Garamond Pro OTF for Garamond postscript font. I'd guess that some extended characters will give problems but I have not yet tested that.

Yes, I do most page layout work now with InDesign but I still like PageMaker. It is simple, ultra quick in Win7, and while I still often have to think how to do things with InDesign, it is second nature in PageMaker. And there are few things in basic page layouts which PageMaker cannot do.

UPDATE: See my own added comment following my move from 32-bit to 64-bit Windows 7 (But I'm still able to use PageMaker - in XP mode)
