Extraction fails with big archive created by bsdtar

[Nikos Kanellopoulos]

Configuration

• Keka version: 1.3.7 (5302)
• macOS version: 14.2.1

Describe the bug

I have a big tar file, created by bsdtar on macOS 13 (some time around July 2023).
The archive is about 370 GB.
bsdtar fails to extract it, so I bought Keka hoping I could resurrect my backup.

To Reproduce

Steps to reproduce the behavior:
Right click on the tar file and click extract.

Expected behavior

All files should get extracted

Hi @nkanellopoulos

You could try using 7zz or unar if you you are comfortable using the Terminal:

/Applications/Keka.app/Contents/MacOS/Keka --cli 7zz x "/Volumes/CRUCIAL_4TB/_LOUSIOS_BACKUP/nk-Jun03.tar" -o"/Volumes/CRUCIAL_4TB/_LOUSIOS_BACKUP/nk-Jun03-7zz"

/Applications/Keka.app/Contents/MacOS/Keka --cli unar "/Volumes/CRUCIAL_4TB/_LOUSIOS_BACKUP/nk-Jun03.tar" -o "/Volumes/CRUCIAL_4TB/_LOUSIOS_BACKUP/nk-Jun03-unar"

You may need to give some file access to Keka, if the Terminal command asks for it:

Thank you!

7zz seems to be much more robust than bsdtar, which fails to extract its own creation...
