The next "logical" step I took was to look at them in Recycle Bin.
Now I have to re-download all of them.

The files I wanted to delete was only C, I deleted them by selecting everything under the Maps tab of C, but it turns out that files from A and B are deleted too. I have "Map displays only web sites belonging to the selected Project" selected.
That`s how I "accidentally" deleted wanted files.
