Hi found the problem mime type for .zip files on my debian box are application/zip and fusecompress is looking for type application/x-zip CompressedMagic.cpp is the file with the list [snip] signature.asc Description: Digital signature

I cannot make out what you are saying. sorry. my uncompressed directory is /backups/.max, it is fusemounted to /backusp/max. the file /backups/max/max/alex.zip is being compressed - when I check /backups/.max/max/alex.zip it is being compressed. where as a file /backups/max/max/alex.bz2 doesn't get compressed such that unzip -l /backups/max/max/alex.zip works and unzip -l /backups/.max/max/alex.zip fails with corrupted file hope that clears it up alex Ritesh -- I think if you know what you believe, it makes it a lot easier to answer questions.

I was testing this when I was looking at the fusecompress_offline which can work with the normal fs. I am presuming the magic sequence is so that you can identify which files have been compressed from the man page fusecompress_offline - decompress or compress data without need to mount the compressed virtual filesystem Ritesh signature.asc Description: Digital signature
