rem *** pathToBackupFiles ********************************************************************************************************************
rem This describes the full path to your Windows backup files.
rem
rem Example:
rem If you have set the path to the files to \\nas-storage\backups\myname-PC you would need
rem to enter this path PLUS the PC name. This is where the backup files are stored.
rem Unfortunately the command FORFILES does not support UNC paths which means that you will have 
rem to map the UNC path to a network drive first. You can do this by using the command "net" like this:
rem
rem -----> net use b: \\nas-storage\backups\myname-PC\MYNAME-PC  (where b: is a variable network drive letter)
rem
rem Please double check the path before running the script. The code line for simulating the deletion is
rem enabled by default. In order to enable the file deletion you will have to uncomment the line for real deletion
rem
rem -----> REMEMBER: YOUR FILES WILL BE DELETED PERMANENTLY WITHOUT FURTHER PROMPTING
