Some times due to some reasons, Folders/Files/Home opening with VLC in Ubuntu. Because of you have most likely done the same for a folder with VLC in the past with this tick engaged (annoyingly it is ticked on by default) which causes the problem initially.
Solution for this problem is very simple:
On any folder in your /home partition, right click and choose “Open with other application”.
From the list choose “Fie Browser”
Finally ensure the tickbox for “Remember this application for “folder” files” is TICKED.
That’s all !!! Enjoy !!!
