The Miscellaneous files are eating up my memory also; it's using 6.53 GB to be exact.
To view these files: do to settings-->storage--->miscellaneous files.
I tried the list listed above to disable but that only did so much. You can also uninstall all updates for the apps that you don't use. That gave me 1GB, nit much but I need every bit I can get. If I list the miscellaneous will some one let me know if its alright to remove or not?
