Can't delete a folder

Command line time ! Open your terminal and open a root shell by doing

Code:

sudo su -

You will be prompted for your admin password. Next navigate to the folder containing the folder you want to delete

Code:

cd /Volumes/ExternalDiskName/path/to/folder

You can check what process is holding on the the file by using the fuser command, this will spew back a list of numbers with a 'c' after them. Chop off the 'c' and use the process number as an argument to the ps command. Eg:

Code:

Mac-mini:~ tyr$ fuser /
/: 82c 246c 250c 271c 275c 277c 279c 280c 281c 282c 283c 284c 285c 286c 287c 308c 314c 315c 319c 325c 366c 367c 372c 374c 379c 383c 384c 385c 387c 392c 1237c 1364c 1384c 1385c 1401c 1402c 1408c 1414c 1415c 1416c
Mac-mini:~ tyr$ ps -p 246
  PID TTY           TIME CMD
  246 ??         0:00.26 /sbin/launchd

If you want to delete anyway do :

Code:

rmdir nameofyourfolder

If that one doesn't work use this :

Code:

rm -fr Nameofyourfolder

That command is extremely dangerous by the way make sure your folder isn't a link or something, doesn't contain any spaces and you type it correctly. Unix commands aren't known for being very forgiving.
