Types of compression files

[hawkeyefxr]

I have a series of compressed file with an extension of .s01, .s02 and so on. But what is this compression, it's not RAR or ZIP.
Any help appriciated

File compression utilities give the user the ability to break up the compressed file into parts.

A reason why you might do this -- you have a 100 MB file to transfer, but your email service provider only allows attachments up to 10 MB. So, you would use the compression utility to compress the file and divide it up into chunks of 10 MB each.

That's what your extensions look like. You would need all of the pieces in order to extract the file.

[doublepost=1537450225][/doublepost]Sorry didn't make myself clear, I want to know what app will reassemble and decompress these files.

Don't know, but I'd try using a utility that handles multiple compression formats.

I have tried unachiver but it does no recognise them. Don't even know what the format is.

According to a web search .s01 is a Corel Wordperfect file. If it's a compressed format perhaps it might be an old Stuffit file?

I just came across the Stuff it compression as well. Will give it a go later when I am on the mac,
Cheers for the help.

It can also be ZipSplitter. Usually the first or last file is named differently or is an .exe that puts everything together. You can also try opening the first file with any editor if it's not too big and just look at the first bytes they usually give away what it is.

Typically Stuffit utilizes a .sit extension but I've never used it to break files into smaller pieces.

Have you tried using the "file" command from the Terminal?
