[zw963]

Current beyond compare only support old gnu format tar realtime edit.
use file command to probe this format file, will see: "POSIX tar archive (GNU)"
But, new tar default format is POSIX format. file command output is "POSIX tar archive"

From https://www.gnu.org/software/tar/man...ter/tar_8.html,
new POSIX format will as default, but, this new format is not editable in beyond compare.

posix

Archive format defined by POSIX.1-2001 specification. This is the most flexible and feature-rich format. It does not impose any restrictions on file sizes or file name lengths. This format is quite recent, so not all tar implementations are able to handle it properly. However, this format is designed in such a way that any tar implementation able to read `ustar' archives will be able to read most `posix' archives as well, with the only exception that any additional information (such as long file names etc.) will in such case be extracted as plain text files along with the files it refers to.

This archive format will be the default format for future versions of GNU tar.

in openSUSE 42.1 X86_64, we have to create a tar file with --format=gnu to make this file use
old gnu format, and editable in beyond compare.

Hello,

Thanks for the suggestion. Updating our TAR support to work with this new method is something we can investigate, but given our current archive libraries not something we'll be able to implement anytime soon. I'll add these notes to our wishlist for future research.
