If the first 2 letters in each file are "PK" then they're zip file, so get 7-Zip free to unpack the files. I suspect once they're unpacked if they're zip files they're individual files from the file system, only larger files were "split" so the parts would fit on a single diskette, so you will have to figure out how to put the pieces together. If they're not zip files you can still use the hex editor to examine them and see what you can find.

The extensions indicate that the files are a set of backup or compressed data stored to several diskettes since the data would not fit on 1 diskette. They were either created with a backup program or with a file compression utility. The best way to restore them is to determine the program that created them as Daniel R Hicks stated by looking at the first 2 40 would be better characters in the first file. When you run the restore program, it will probably ask for the last disk to get the index.

What is the filedate of the set? It can help in knowing the date it was created and possible software versions popular at that time. Looks like there were at least two versions of norton backup 1E and 2A so your version of norton backup is probably too new. Norton backup on dos seems to be versions - the software linked there seems plausible but there's no way to test it.

I did actually try DOSBox early in this escapade, it suffered the same problem as VirtualBox, where the restore program complains that the disk image has nothing readable on it You hit the nail on the head though, I cant share the files since they are proprietary works of the friend asking me to open them.

And since I don't know how he made them and neither does he, it seems , I cant replicate what he did to make them to better understand it. If I'm understanding correctly, you have a set of.

Is this the file that is shown as "Norton Backup File"? If so, can you give us some blocks of the beginning of it? For example, the first bytes? They should contain enough information to identify the format, but not enough to do anything with it. Wait, "is comical since I can open the pieces with 7-zip just fine"?

Are you trying to open the. Or the extracted file? Clarification of Question by bcrimmins-ga on 26 Dec PST clouseau, Thank you very much for your helpful contribution.

Please forgive my tardy response but with the holidays I have been distracted. I had not seen the article you posted nor the oldfiles. Both were very illuminating and was able to recover the files just fine. This is my first use of GoogleAnswers so I'm not sure what needs to be done next. Should you post your clarification in the form of an answer and then I would except it? Thanks, Bob. Hello Bob, Thanks for replying. I am glad my research solved your problem and I had figured the holidays had your attention.

Thanks for allowing me to post the answer and yes, simply accepting this will take care of things. As I posted above: Have you read this article from th Microsoft Knowledgebase?
