I have an LG 8300. I'm having trouble installing new apps because I get the message that my storage is full. I apparently am down to 20MB of 256MB on my internal storage, but have over 10GB free on my SD card. Yet the device is telling me I can't download apps because my device is full! 
I've moved every app I can to the SD card, my music is on the SD card, I've cleaned out my text messages, and have an app that deletes junk files, yet I can't free enough space. So I basically have two questions:
1) What is eating up all my storage space? Last time I reset to factory I had plenty of space yet over time my internal space seems to dwindle despite moving all my apps to SD. I downloaded ES file explorer but can't find the folder that's holding all that crap. Possibly I have videos taking up some space but can't find how to get rid of them.
2) Is it possible to install apps directly to the SD card? It doesn't seem right that I have all this storage space available on SD but because internal is being hogged up by something I can't download anything more.
Thanks!
