MY OS is Windows 2000 SP3. The date format is mm-dd-yy but that can 
be easily changed (and should be) with no negative consequences. The 
deletion of all directories created more than X (lets assume 5) days 
ago must be automated, invoked from a batch file that is scheduled to 
run every night at 2:00 AM. The only directories it needs to check 
are the directories in the root of the K:\ drive. For example, lets 
say there are three directories located as follows:
k:\05-01-03\
k:\05-05-03\
k:\05-10-03\
I want XXCOPY to simply check the creation date on these three parent 
folders and then delete any which are older than 5 days. It does not 
need to check the creation dates of any sub-directories or files 
inside these parent folders...if the creation date of the parent 
directory (e.g. k:\05-01-03) is older than 5 days, then delete that 
folder and everything in it. If the creation date of the parent 
folder (e.g. k:\05-10-03) is less than 5 days old, then leave it 
alone. I think I would prefer a batch approach 
as you suggest because it doesn't seem that XXCOPY is well suited to 
this task. Any batch file suggestions you may have would be greatly 
appreciated. The batch files I am using now are as follows:

START of C:\WINNT\FULLBU.BAT FILE
@ECHO ON
net use k: /delete /y
net use k: \\joanne\serverbu-joanne
rem the following gets date and time into e-vars
rem Requires c:\winnt\CURRENT.BAT
ECHO.|DATE>c:\winnt\TEMPDTTM.BAT
CALL c:\winnt\TEMPDTTM.BAT
md "k:\%DATE%"
xxcopy "c:\company data" "k:\%DATE%" /y/v/e/s/c/i/h/r/h/ze/nx/on"k:\%
DATE%.txt"
xxcopy k: /rs/s/h/r/pd0/ed/db#5/fc/y/on"k:\deleted-%DATE%.txt"
net use k: /delete
END OF FULLBU.BAT file

START of C:\WINNT\TEMPDTTM.BAT
Current date is Tue 05-06-2003
Enter new date (mm-dd-yy):
END of TEMPDTTM.BAT


START of C:\WINNT\CURRENT.BAT
if '%1'=='date' GOTO IsDate
set Time=%3
GOTO End
:==== IsDate ====
SET DayOfWeek=%3
SET Date=%4
:==== End ====
END of CURRENT.BAT
