I noticed that my youwave_vm01.vdi file is getting quite large, and so I decided to do a cleanup of certain files inside youwave, most of all, pictures and audio files. The thing is I noticed that even after deleting files, the size of the .vdi file stays the same, even though youwave's system reports that there is 575mb of available space out of 784mb total space; that does not add up to the 479mb of the .vdi file. Internal storage also reports that there is 629mb of available space.
I would really like to know what's going on with the storage of data and why the .vdi is so large, even after erasing many files. If anyone can provide some insight it would be much appreciated.
