Create a Date Batch File

Hi,
I'm going back in time here,.....

I want to create a 'batch file' that when i run it, it will remove some files from a folder.
These files are in a date format YYYYMMDD (IE: 20110112.bak)

I want to delete all the files except the current date when the batch file is ran.

@Echo Off
SET M=%DATE:~4,2%
SET D=%DATE:~7,2%
SET Y=%DATE:~10,4%
SET MyD=%Y%%M%%D%
Echo %MyD%

*** the command above displays the current date
I'm not that good with IF statements....

How can I make this happen?
Thanks,
Bill

 

If you want a good reference, try 'Windows in a Nutshell' (O'Reilly, 2002) by D. Karp T. O'Reilly and T. Mott, ISBN 0-596-00249-1. It has a good section, pages 395 to 435, on DOS commands and batch files.

Actually, as you have generated the current date, it looks fairly straightforward:

IF %MyD%.* COPY C:\TEMP
DEL C:\TEMP *.*
COPY C:\TEMP [to original directory]

The above will check the current directory for your 'date' files and any it finds it will copy to a TEMP directory. It will then delete all the remaining files and return the copied ones. It's a bit messy but I couldn't see a way round the copy and re-copy.

NB: This is offered in good faith but with no guarantees!!
