In Linux it is very easy to hide files. Just mark a file, rename it and add a “.” (rightclick > rename or simply click F2).

Example:

* Visible File: text.txt * Hidden File: .text.txt

If you do not want to rename the file for some reason, create a new file named .hidden and open it with a text editor. Enter the files you want to hide and save it.

If you want to see hidden files, simply click on “View > show hidden files” in your filemanager.
