 # MST (Move & Symlink Tool)
 
+MST searches for large or old files and moves them to another drive (e.g. external hard disk) to avoid filling up your own

 >**Not all functions are implemented yet! Right now MST is in an alpha stage.
   Attention! It is strongly discouraged to run with sudo rights	or run with system / program files**

 ### Information
 - MST only runs with Linux OS
 
 ### The following is still being implemented
-* Move whole directory to another place and make optional tar or zip file.
 * Maybe Windows support.
