I just installed mDigger on my Windows Mobile Pocket PC phone's storage card (to save internal memory space), created an account online with mDigger, chose my channels and successfully logged on from my WM phone and started the sync progress.
Unfortunately during setup and sync there is no mention about choosing whether the channels are to be stored in internal or storage card memory. I noticed during my intial sync that my internal storage memory was depleting more and more and had to try to cancel the initial sync (which didn't work). I ended up having to do a soft reset.
I incorrectly assumed that because I had installed mDigger to my storage card that it would also store all if it's downloaded channel date on the storage card too.
It would be handy if during the intial installation and setup that users were able to determine where channel data is to be stored before their first sync.
