Public bug reported:
When I compress a file with mscompress on Ubuntu 10.04.4 LTS amd64, the
compressed file is indeed created with "_" appended to the file name;
but when I try to decompress that file with msexpand I get the following
error message: "This is not a MS-compressed file" -- and the file is
expanded correctly. A file command on the compressed item returns only
"data", whereas it should be "MS Compress archive data".
I tried with an Ubuntu 10.04.3 i386 LiveCD with which the file command
returned the correct answer and msexpand didn't return any error
messages, so it's probably an architecture problem. Many thanks to
Stefan Handschuh, the developer of jAOLT, who advised to use the file
command and suggested that the header could be incorrect.
A terminal output would probably be more explanatory:
zapman@ubuntu:~/mscompress_test$ mscompress -V
mscompress version 0.3 (yellow) Mar 7 2010
zapman@ubuntu:~/mscompress_test$ mscompress TODO.txt
zapman@ubuntu:~/mscompress_test$ dir
TODO.txt TODO.txt_
zapman@ubuntu:~/mscompress_test$ file TODO.txt_
TODO.txt_: data
zapman@ubuntu:~/mscompress_test$ mv TODO.txt .. #so that msexpand doesn't say
"File exists"
zapman@ubuntu:~/mscompress_test$ msexpand TODO.txt_
TODO.txt_: This is not a MS-compressed file
zapman@ubuntu:~/mscompress_test$ dir
TODO.txt TODO.txt_
You can see the reply of the file command which should have been "MS
Compress archive data" instead of just "data", and the error message
from msexpand which says "This is not a MS-compressed file" and which
shouldn't have appeared.
