Missing 20 Gigabyte of Free Space I've recently noticed that my Galaxy Note 3 32GB model ran out of storage. My Samsung File Explorer App says that I've got about 3GB of storage left of 32GB. 
My problem now is that I can't figure out where the remaining ~30GB (I know that there aren't really 32GB of free space) are? My SDCard directory has a size of approximately 10GB, plus I've got about 6GB worth of apps. That means, I should have 16GB left (or less) instead of 3GB? 

Here's a table:

Files:         10 GB
Apps:           6 GB

Free Space:     3 GB
Total Space:   32 GB

Either is the total space more like 19GB instead of 32GB (That would be kinda much, right?) or there are hiding some files somewhere worth about 10GB.

Any suggestions? 

Best regards
Thats a big diff but maybe you use spotify with offline files or something?
Also its worth checking Settings->Storage. Click on "Cached data" for instance and clear, here you see what it taking space more in detail.
