USB Storage / SD Card question

view full story

http://androidforums.com – Hi guys! Just noticed that my USB Storage of my Galaxy W is close to Full. Did a bit of research and apparently, "USB Storage" is just some sorta partition of the internal memory, right? Supposedly each and every update gets dumped here even if the app is saved in the SD card. So would it work if I just moved everything from this folder to my SD card? I did connect my gadget to a PC via USB cable, and I got access to both folders. Moving everything is easy, but I'm wary that this might cause some apps to malfunction or something. Thanks! (General)
