"Get a local copy" question

I'm just starting to use Workgroup PDM.  When I check out a project I always select "get a local copy" which downloads the files to my local HDD.  Currently the working directory is "C:\Users\~\Documents".  How do I change the working directory to a different local drive?  I have a partition on my local HDD that I utilize for all of my data and I would like for that partition to be the destination path.
