Hi guys, I've been searching in the forum but I still haven't found a solution.

This is my first time using VC. I use a Linux Mint 20.1 Cinnamon laptop with 240 GB SSD and 500GB HDD. Months ago I created a 100GB volume in the HDD with very basic configuration. Put a few hundreds of files in there and now for the first time I tried to extract the files to another area in the HDD. All files were extracted but now when I try to access the extracted directories, they are all empty and I can't delete them. And when I try to access the VC container, it's just too painfully slow. I can see the directories but not the files. They take way too long to load. And it's been like that ever since. Thanks to that, I can't access the extracted files and can't access the files in the VC container. Any clues?
Thanks in advance!
