Format of Cisco "tar" files

[frank.ring]

Hello,

I make backups of the AP's images to our TFTP server and have tried to open the "tar" files under linux to check the contents.

This does not work. What type of compression is used by Cisco?

Use 7-Zip.

     - What error do you get on linux when trying ?

The command I use in Linux is: tar -tvf "archive-file.tar"

Output: 

tar: v: Cannot open: No such file or directory

tar: Error is not recoverable: exiting now

File does not exist.

  - The syntax of your tar command is simply wrong :  tar -xvf filename

If you only won't to see the content - tar -tvf ist right.

@ Leo: 7-Zip work's perfect. 

@ rrudling: bsdtar work's perfect too!

Thank' for your support  - problem solved.

Works fine for me with Windows 10 tar (bsdtar 3.5.2 - libarchive 3.5.2 zlib/1.2.5.f-ipp):
