Sometimes I have accidentally deleted files or folder (using shift+del) without realizing that they were selected while I was deleting another file. Is it possible to disable that check box in the upper left of the file or folder's icon?
I usually press an Esc key when I am working with large number of folders or files and want to make sure that I only have 1 selected. If you press Esc, then all highlights are reset and you can select whichever file you want. You can get used to it very quickly, took me 1 file sorting session to master it :)
