#1478 compressed tar doesnt open as tar

[Sergey Arsenyev]

1. I've created tar on Linux as tar -cf test.tar.lzo {some files} --lzop
   There are other archives in this files (ie *.docx etc)
2. When I try look to test.tar.lzo from 7zFM (in Windows) or 7z l test.tar.lzo I see internal archive structure:
   
   Path = test.tar.lzo
   Type = zip
   Errors:
   Headers Error
   Unconfirmed start of archive
   Warnings:
   There are data after the end of archive
   Offset = 254
   Physical Size = 951
   Tail Size = 2784770

Same with lz4.

Tar contains ZIP.
Probably lzo stores some data uncompressed.
But 7-zip doesn't understand lzo.
So 7-zip searches another signatures. And it tries to extract that zip, when it finds ZIP signature.

Is any chances to add lzo,lz4 format compatibility to 7z.dll?

[Igor Pavlov]

I don't plan lzo and lz4 support in near versions.
