UNERASE use in DOS

Specs: Windows 98, 16/16
Undelete

I was told way back when here that there was a way to install UNDELETE or UNERASE function into the DOS layer. I am doing an awfull lot of CAD drawings that come in on the DOS level, and then due to third-party software, they get erased. I get an old file representing a new one then, and the Re-cycle basket only works when going.

How can I re-install UNERASE into a common old Win 95 or a WIN 98 computer. Wadda I got to have add how to install it then.

UNDELETE was the msdos utility and UNERASE was norton utilities, although maybe other undelete utilities were named the same.

They work OK on my 98 system but I need to reboot or exit to dos--not a dos window--to use them. And the OS needs to be on a fat16 and not a fat32 partition. Undeleting files on a fat32 partition must be harder and I've never found a command that works like undelete and unerase do on fat16 partitions.

Also, it's going to depend on how they were deleted. When a file is deleted in dos it just erases the first letter of the file name. UNDELETE and UNERASE locate those files and then you enter the first letter to restore the file. If files are erased in some other way then I don't think those commands can recover them.

Otherwise, just copy the dos 6.22 undelete (or NU's unerase) command to your windows\command folder.

I only have the disks for 6.20. Is the function on them? My whole system(s) was never converted over to FAT 32, it is still at FAT 16. Will this present any problem?

I use the F-8 and Cnt'l key a lot now. Most of where I need such capability is on the Win 95 computer. Can I simply copy over the *.exe from one of the disks, or something different, plus a combo this or that then?

Zero mentioned in my book on this.

UNDELETE is in the olddos.exe download:

http://support.microsoft.com/kb/135315

It's dated as if it's a win 95 utility but it's the same file size as what came with 6.22 so I think they just changed the file date. When you run olddos.exe I think it extracts to whatever directory it's currently in so you might want to put it in a temporary directory to extract it and then take a look at all the files and copy whatever you want to windows\command. It also includes the memmaker files.

Fat16 is what you want if you're going to use UNDELETE.

I'd have to email you unerase from NU if you want that too.

I remember the Memmaker files. That worked great, until the CPU went dead.
