I just downloaded some materials, but the extensions are not recognized by Ubuntu.
I have a bunch of files names
name.iso.002 and so on.
How I can extract or mount it?
These filenames look like those produced in Windows by QuickPar when used to split files (particularly video files including iso files) and can be rejoined by Quickpar and repaired at same time if needed with par files supplied.
I used WINE to install QuickPar in Ubuntu and used it to join the files. I think only Quickpar can rejoin what it has split.
