I have a Samsung Galaxy SII which I use as my music player more than I use as a phone. Lately when putting music onto my phone I've been getting two different error messages, this is one: The other says something to the effect of "cannot copy file root is too deep". However, I can copy the files to a thumb drive, then copy the files to my work PC and from there to my phone without issue. So the problem appears to lie between my home PC and my phone. I tried updating the drivers on the USB ports but they were up to date. Any suggestions?
