Delete all files older than one week.
Michael Haupt
As mentionend in the Subject I need a BATCH-File which deletes all files older than one week (for a backup-routine). Does anybody
know how i can implement this routine within a BATCH-File?

@echo off
FORFILES -m*.* -d-8 -c"COMMAND /C echo del @FILE"
remove the echo to make it functional
FORFILES v 1.1 can be found here:

This is a followup to my own post which had COMMAND instead of %comspec%
in the line above, and strangely enough COMMAND would not function as
expected.

Windows 95/98/ME only: here are two example Batch files
that use no third-party utilities.
1) Using a Debug flick-back script to calculate date seven ago
This uses nothing outside a default Windows 95/98/ME installation
2) Using Microsoft WSH to calculate date seven days ago
Either technique handles month/year ends (and leap years, too).
In each case run the demo with the folder concerned as the
first parameter:
demo.bat C:\FOLDER
1) Using DEBUG
This technique uses Debug to flick the system date back 7 days
for an instant, creates a file with that date, returns time to now,
then uses the discriminant file to do the deletions.

Note 1
WSH (Windows Script Host) enables routine tasks to be handled in either
VBScript or JScript. It's available as a free downloadable add-on for
the tiny proportion of Windows machines (mostly older Windows 95 ones)
which don't already have it (in one version or another). Documentation
is included as an HTML help file, and includes cut-and-pastable syntax
examples in VBScript and JScript for all features.
Windows Script Host information/upgrade-to-current-version/downloads:
http://msdn.microsoft.com/scripting/
By default, WSH installs CSCRIPT.EXE which is a Batch file
interface allowing all WSH functionality to be run from a normal
DOS-style Batch file. This interface provides Windows machines
with a massive extension to the traditional Batch functionality.

With FORFILES, you need to include the .COM extension
when you use COMMAND.COM explicity, as in:
============Screen capture Windows 95
C:\WORK>ECHO.>UniqueFileName.EXT
C:\WORK>forfiles -pc:\ -s -mUniqueFileName.* -c"command.com /c ECHO.DEL @FILE"
DEL "UniqueFileName.EXT"
C:\WORK>
============End screen capture

You can also use this sort of syntax:
forfiles -pc:\ -s -m*.XYZ -c"command.com /c ECHO. Found file @FILE"
to ECHO that message about all files matching the mask if COMMAND.COM
is in the path. But note that you _must_ add the .COM extension
for FORFILES to work.

HUNT *.* b#-7 "del" u
(via sig line 3) will do that; omit u for test. It can also detect on
filename, scan subdirectories, etc. Here b#-7 means before the
beginning of the day 7 days ago; if you want exactly 168 hours, see my
NOWMINUS.
Avoid "solutions" that alter the system clock, however briefly,
especially if other programs are running at the same time (e.g.
Windows).
Be careful not to delete too much.

Or use %COMSPEC%.
