Why joining parted *.tar is missing files, when *.tar itelf have them?
 

I have 25 .tar files like: When I want to unpack them with it does, but missing files: whole .tar is 1,2 GB, but unpacked files have just 600MB - I have ~200 files missing out of ~400.

Ive tared them using 7zip on my Windows OS: Little image what I mean: http://i.stack.imgur.com/Dao7E.png

off hand i would say you only joined 1 AND 25
and not 1 through 25
-- or--
do the the fact that the terminal reads files NOT in the human order
human = 1,2,3,4,5,6
computer = 1,11,12,13,14,15.. 19,2 , 21,22,23,24,... 29,3


cat
will work but for 25 files it would be easier to use lxsplit
the linux version of the windows ljsplit

http://lxsplit.sourceforge.net/
even though it is 4 years old
the source dose build with gcc 4.6 on modern OS's
