Mate, open a folder, click tools, folder options, go to the "View" tab, and select the box "Do not show hidden files".
Then right click on the file you want to hide, click on properties, and tick the "Hidden" box at the attributes section. The file will hide.
Then if you ever want it back, go back into a folder, to tools, folder options, "View" tab, then tick the box "Show hidden files".
Think that's what your looking for......!
