Handling folders in a batch

[Helge Haensel]

Hallo NG!

Once per week I generate a (backup-)folder named YYYYMMDD.
When there are 5 or more folders the oldest 5+-folder(s)
should be deleted. How can I achieve that?
I checked with the help-command at cmd-prompt, but didnt
succeed with the dir-, for- and other commands.
Sorry, it is to tricky for me.
Thanks.

A backup script (.vbs) found in google search is at
http://www.michaelhorowitz.com/backupscript.html
I copy/pasted his .txt version to desktop and it looks like you might be able
to take parts of it for your own purposes. Too bad the mainframe OS concept
of generation data sets does not exist on P.C. There is more to find on
scripting
from Microsoft.

Here we go again . . .

Line1 @echo off
Line2 for /F "tokens=*" %%* in ('dir /ad /b /tc /o-d d:\Backup ^| more +5')
do echo rd /s /q "%%*"

The batch file will leave the 5 most recent folders in d:\Backup
and remove the rest.

Remove the word "echo" to activate the script.
rest.

If this appears to do what you intend, remove the word 'echo' from
line 5.

Hallo, thanks to all you guys for suggestions. I will carefully
study and try them.
This surely will stabilize my backup-strategy.

Hallo!
I studied all 3 versions. Will's link is a little bit to complex.
I could have written that also using my VB system. That is what
I tried to avoid.
Phil's and Pegasus's versions are about identical and work perfectly.
Thanks!
Helge

If you ever score a reply from Phil Robyn, use it! He must
be the undisputed master of batch files. I've learned a lot
from him.

Gee, thanks, Pegasus, that means a *lot* coming from you!!! I have
