It's been more than 6 months since I last used Ubuntu. It happens it was 14.x (can't remember which). I still have the install on an attached HDD but it became corrupt and won't boot. I'm pretty sure Linux distros have the same sort of functionality as Windows, in that they will remember 'saved' locations. Take a trawl through Google, or even the Ubuntu Help File (not too sure about that, wasn't much use to me) to see if you can find a way to alter and / or clear the history settings.
An alternative solution: make a folder somewhere called .Into (notice the dot in front of the name - it gets displayed at the top of the tree, in Windows NTFS file system it would be an underscore). Save IHG stuff into that, then move to wherever.
Please Note - I'm not trying to fob you off on this, It's just that don't think it's an IHG issue, I think it's o/s.
