I have this problem and looked in my folders trying to find large files using ES File Explorer. I have found a repeating set of folders here:
/sys/module/usbhid/drivers/hid:generic-usb/module/drivers/hid:generic-usb/module
These folders keep going and going and going. I tried to look at the properties of the sys/module folder but the file size kept going and going and going. I ran it all night and it was still running in the morning at 1.25GB and counting. Is it safe to delete the repeating set of folders? Does anyone know what these folders are used for?

The /sys directory is a virtual filesystem. It is created dynamically by the kernel, and contains information on the hardware as well as various kernel settings. It also allows you to change some kernel-level settings. It does not actually exist on the disk; it is mounted at /sys during boot, so there is nothing to delete. Due to its layout, any attempt to calculate its "size" will probably never end, since each directory usually contains a link back to its parent system, thus setting things up for an infinite loop... at least until you reach the maximum path length.
Just in case you are not familiar with Linux/Unix systems, there are no drive letters. Instead, disks/partitions are "mounted" at some location in the directory tree, which starts with "/". As an example, "/data/example/file1" could be on a separate disk from "/data/file1".
