I have a Samsung Galaxy Ace. Every time I try to install a new App I get a message saying my internal memory is full (the SD card has plenty of room). The phone has 180MB of internal storage. I counted the memory that all my apps should take and it came out to 50MB so something is taking up 130MB and I don't know what that is. I rooted my device and moved all the apps that could be moved to the SD card. It still says that I have only 20 free MB. I was wondering if there are any apps out there that can tell me what is taking up all my memory. If not is there any way to programmatically map out the internal storage of the device? Does Android block access to this storage, or can I view it from my computer in any way?
