Defragment a file or a directory
-v be verbose
-r defragment files recursively
-c[zlib,lzo] compress the file while defragmenting
-f flush data to disk immediately after defragmenting
-s start defragment only from byte onward
-l len defragment only up to len bytes
-t size minimal size of file to be considered for defragmenting
