Hi,

I compressed a folder with the following script:

...
for i in *.*.*; do
         file $i | grep bzip2 >/dev/null 2>&1
         if [ $? -ne 0 ]; then
                 echo "Compress: $i"
                 cat "$i" | bzip2 -9 > ../tmp/$i
                 if [ $? -eq 0 ]; then
                         mv ../tmp/$i $i
                 fi
         else
                 echo "Alread DONE: $i";
         fi
done
...

it works mostly, but there seems to be at leas one messages that cause a 
problem, during syncing the whole folder or performing a search, I get an 
assert:
