Huge file in Kobo Aura internal storage
So my Aura was complaining that it can't update as there isn't enough free space in the internal storage. This surprised me as I store all books in the SD card and even that wouldn't be enough to take up 4GB.
So I opened the internal folder in Windows Explorer and found a strange folder with a string of numbers as its name. Within this folder were numerous files and one folder named "cpbf" followed by a string of zeroes. Within this folder are 3 files, one of which is named the same as the original folder and the other 2 are "cpbdf" and "cpbmf". The size of "cpbdf" is 2.9GB.
Any idea what this file is and why is it so big?
