Can not extract all files in tar.gz

[charlie123]

Windows 7, TC8.51

I got a tar.gz file from Gitweb. But TC can only extract some files, missing some files and folders.

I tried Winrar, it said corrupted file. I tried Winzip, it can extract. Is this is some kind of new format of tar.gz?

Thanks!

What about some example to test, or how do you expect someone to respond ?

Maybe they were just links?

I also have problems with tar.gz files.
The last example is tar.gz files from this page https://susestudio.com/a/TadMax/owncloud-in-a-box#
Maybe its a new format version. Totalcmd cant read the file list and just shows one gibberish file inside the tar.gz

Can you provide a sample file that doesn't require a log-in and is not several hundreds of megabytes in size?

I just split the file with totalcmd. Here is the first 1.5Mb

When you open it with winrar it shows one folder with two files inside, but totalcmd show one corrupted filename.

Any idea what file created this GZ file?

The GZ header indicates (in the 4th byte) that the name of the packed TAR file is stored in the header of the GZ file, and the name is ²¤RA. RAR does not use the TAR name, it just extracts the TAR and shows the name of that TAR.

[Mummu]

I'm not sure, but the name of the tar file is at offset A4BE, after the the whole header index, and not in the beginning where ²¤RA is.
Actually the ²¤ in hex is A4B2, so it must be a pointer to the filename. And when you add the bytes before it, you get exactly the filename offset.

That's odd, I cannot find that in the GZIP specifications:
https://tools.ietf.org/html/rfc1952

It must be some third party extension. That's why I'm asking whether you know what program created that file...
