I need to retrieve the data off of 2.5 diskettes. I do not know what software was used to do the accounting on them. They are from 1993-1998. I have an XP that has a disk slot. I really need these to open and print the information. There are not any copies. I downloaded Dosbox but I can not get it to mount. The first disk is labled: CPBACKUP.001
I hate to be rude, but everyone here is way off.
These are backup disks created by the backup software that came with MS-DOS 5.0 or later, or one of the early Windows versions, such as 3.0, 3.1, or 3.11. The "CP" in the backup name stands for "Central Point," the company that made the backup software for Microsoft DOS and Windows.
I recommend that you get an older PC (Should be cheap) prior to the year 2000, with a 3.5" (You said 2.5 diskettes, but there is no such size. It's 3.5") floppy drive.
You should also make sure this PC has a good working Hard Drive with at least 5 MB of free space for every disk you are seeking to restore.
Install MS-DOS 6.22. Locate and start the DOS version of the backup software first (DOS is faster and less limited by the multitude of Windows configuration settings), and choose the restore function. It should prompt you to enter the first disk in the backup series ".001" If the backup disk series were encrypted when they were made, you may be asked for a password to restore the files.
If that doesn't work, install Windows 3.1 on top of the DOS you just put on that machine, and use the Windows version of the backup software.
If this doesn't work, then I suggest you write down any error messages, and post them here along with a link to a copy of that first backup disk imaged (using disk imaging software) and uploaded to your Google Drive account. I can examine the header information of this image and determine if we need to use a different version of the backup software, or if you feel confident enough, you can do this yourself.
Good Luck!
