HCP:
It is as you say, I just noticed that around 10 GB was wierdly missing, and I had no other installations or anything like that.
Im using Windows 10.
kahc:
Yes, or at least I have tried to, but since it is located on the external harddrive it is no folder on my C-drive / or I can't find any folders connected to bitcoin. Should there be even if I installed it on the external harddrive?
Could be some residual files before it fully moved to the external disk, I am not really sure.
But the AppData folder is hidden, you can access it by typing %appdata% in the "Run window".
Hold down "Windows key" + "r" , then type in %appdata%
If still nothing, then download
WinDirStat and see if can locate where the 10GB is from.
Could also be system files(hibernation, system check point, cache, etc,.....)
