File Erase based on date

[Mashup]

I wish to erase files created daily in a directory - a week after they have
been created - as a scheduled task. Does anyone know of any way of deleteing
files based upon creation date?

Cheers

Chris

Because I'm lazy and very busy, I will propose only an outline of the steps.

1. Use XCOPY with these switches /L/D:mm.dd.yyyy and redirect
to Exclude.txt to create a list of files that have been
created within the last week.
2. Invoke XCOPY again with these switches /L/exclude:exclude.txt
and redirect to Delete.txt to create a list of all files
except those that are listed in Exclude.txt
3. Use a FOR command to delete each file listed in delete.txt.

The trick will be to specify or calculate mm.dd.yyyy. Also, XCOPY will
require the source and destination paths.

There are several batch gurus here who can fill in the blanks.

Ray - thanks. Problem is I am stuck specifying the date - like you say. I
would like a way for the batch file to pick up the date from the OS
(Regional settings) - and we schedule once per week. So far I specify:

XCOPY C:\DIRA /L /D:%1 > EXCLUDE.TXT
XCOPY C:\DIRA /L /EXCLUDE:EXCLUDE.TXT

But the command cannot recognize the date as in mm.dd.yyyy etc....

Any other help / ideas appreciated.

Cheers

Here's how to get the date in the format mm.dd.yyyy:

for /f "tokens=2,3,4 delims=/ " %%a in ('date /t') do set zdate=%%a.%%b.%%c

[Raymond Zeitler]

Unfortunately, the date that's required is one week before the current date.

I have to small utilities that allow you to delete files based on thier
date. One is called DELAGE, and the other is called PURGE.

These are both 32 bit console programs and they work very well for me. I
use them in batch scripts to scan a public access share on my network on a
daily basis and delete ANY files older than 2 days.

Where I can get this programs?

I have to solve the problem that I must delete files that are older then one
month or 30 day's.

Thanks in advice.

DATE:
I use a variable in the enviorment.
add varible. date1
and just each day, reset the date manully.
then the rest is done automatically.

you can use it like this: IF EXIST 3.HTM COPY %date1%hk.htm+3.htm
that is just a copy of a line in abatch file to add htm pages into a
single htm file dated today.
for you:
%date1%hk.htm this is the part.

the rest of the file, others have mentioned.
this is just date help.
luck, Haart
