Parameters

• /t or /time
  Time specification (see below)
• /p or /path
  (Start) folder
• /f or /filepattern
  File pattern. If omitted, all files are scanned (equals /f=*.*).
• /s or /subfolders
  Recurse subfolders yes(1) or no(0). If omitted, only the folder passed via /p is scanned for matching files (equals /s=0).
• /rb or /recyclebin
  Delete to recycle bin instead of permanently delete. If omitted, defaults to 0 = delete files permanently.
• /r or /readonly
  Delete readonly files? If omitted, defaults to 0 = don't delete readonly files.
• /pp or /processpriority
  Set this process' priority to Idle ('i' = lowest possible) or Below normal ('b') in order to consume less (mainly CPU) resources.
• /hc or /hideconsole
  Hide the application's (console) window? Yes(1) or no(0). Defaults to no.
• /la or lastaccess
  Compare to a file's LastAccessTime instead of its LastWriteTime.
• /fst or /filessmallerthan
  Only delete files smaller than the specified file size (see below how to pass file sizes).
• /fgt or /filesgreaterthan
  Only delete files greater than the specified file size (see below how to pass file sizes).

Please note that you may only use either /fst or /fgt. You can't use both parameters. If you happen to pass both parameters, the last one 'wins'.

You may specify more than one file pattern for the parameter /f by using ; (semicolon) as a separator, e.g.
/f=*.doc;*.rtf = deletes all *.doc and all *.rtf files from the specified folder.
/f=Backup*.bak;Log*.trn = deletes all Backup*.bak and all Log*.trn files from the specified folder.

d = day   e.g. 1d
w = week  e.g. 2w
m = month e.g. 3m
y = year  e.g. 4y
