As part of our nightly build process, we would like to rename the prior build folder to something that contains the date & time. Eg:

c:\DEV =\> c:\DEV201104052300

I haven't figured out how to do this but I thought that I might be able to setup a variable with the Date/time and append that to 'DEV' which I can then use in the rename action.

In addition, I'd like to be able to delete old build folders that are older than a specified number of days.

Thanks,

Charles&nbsp;

Hi Charles,

Edit: Go with Steve's (below), his is a bit cleaner and doesn't resort to a script action. I'll leave mine attached just in case you want to see an different way to achieve the same time.

Cheers,

Hi Charles

I have attached a simple example that should help.

&nbsp;Thanks to both of you. I am still getting to grips with FB and of course I should re-read the help each time I think of a question as the answer is probably in there&nbsp;
