Ubuntu - hide files or folders

To hide files and/or folders in Ubuntu you have two ways:

1. add a '.' (without quotes, obviously) at the beginning of file's/folder's name
2. if you don't want to rename the file/folder do this: in the same folder as the one in which are saved the files/folders you want to hide, create a new text file, and edit it writing the names of the files/folders you want to hide. Then save it and rename it as ".hidden" (without " too)

To see hidden files press CTRL+H.
