I toggled in 7zip the option for files with the .001 extension to be opened with 7zip (x64). After having attempted to extract the .001 file, I recieved an error frm 7zip indicating that the "CRC failed" and that the "ISO is broken". Rar, however, extracted the ISO perfectly (that is, without problems). I proceded to extract the .001 files in the same manner with both programs:
I first right-clicked xxxx.001 and chose open with -> program (WinRAR and 7zip). Then I pressed the extract button in the top panel of both programs. WinRAR was successful, while 7zip was not.
My speculation: 7zip only extracts the .001 file, and does not procede to extract the following files in the archive (.002, .003, etc.), while WinRAR does. Evidence for this is the fact that 7zip competed unsuccessfully after only 5 or 10 seconds after the extract had started.
Is there a way to configure 7zip (latest x64 version) in order to fix this problem? Thanks!
