The first statement uses the expr anchored pattern match to remove everything in $FILE upto the last '/' this is pretty much equivalent to basename $FILE

The 2nd statement uses sed to delete all occurances of $FILENAME from the $FILE string, no doubt this is trying to duplicate the output of dirname $FILE, but it would fail if the FILENAME string matches components of the path eg /work_files/mydir/work.file.

You would probably be better of replacing these two lines with:
Code:
FILENAME=$(basename $FILE)
UNPACKDIR=$(dirname $FILE)/
