Lena can be used to create yourself a personal folder, i.e. a folder your user is the only one who can access it (other users cannot even see the folder in the file tree).

To do that, you need:

• To be the only owner of the folder. If not, ask one of the current owners to set you as the unique owner of this folder (cf. File/folder's owner).
• Grant yourself the full rights (“Can do everything”) on this folder and give none to any other user/group (cf. Manage access rights).
