CMS Lite no overwrite feature

Hi,

I have a Magic DVR (standalone) and I'm using their CMS Lite software to view and record from a remote location. So far it has been recording 4 camera feeds for a few days straight and it seems stable. However it is recording to a secondary 3TB HDD on my Win7 machine and there is no overwrite feature in the CMS software (why I am not sure). So in about a month that HDD will be full.

Is there any program that I can use to just recycle that directory when it gets close to full? Or do you guys recommend any other CMS software that has an overwrite function? Thanks.

So I created a batch file with the commands below:

REM Remove files older than 14 days

forfiles /p "C:\my dir" /s /m *.* /c "cmd /c Del @path" /d -14

And then I ran Task Scheduler and set the batch file to run daily and delete files older than 14 days old. That lets me keep plenty of vids, while never filling the HDD (which actually caused the CMS to crash, ha), and I don't have to do anything manually. Hope this helps someone in the future.
