psrm
psrm - Partial secure remove - the fast file shredder.
This program overwrites the given file(s) with random data. The percentage of the file to overwrite is set by the user. The whole file is then deleted.
Useful for speeding up the destruction of large files that do not need to be entirely destroyed, but a standard delete is not secure enough.
This software is used at the users own risk. The author takes no responsibility for data loss.
Released under the GPL 3 licence.
