So to protect your important files in Ubuntu follow these steps.

STEP 1:
Create a new folder anywhere you want, and again create new folder inside that folder. Lets consider we have created two folders “TheChetan.com F1″ and inside that “TheChetan.com F2″. Now put all your important files inside inner folder “TheChetan.com F2″.

STEP 2:
Right click on 1st folder i.e. “TheChetan.com F1″ and Go to properties.
Then select “Permissions” tab. and then select “List files only” in “Folder access” option. If you have multiuser system then do same thing for all users by selecting the proper group.

In just two steps you have protected your files inside a folder, Now when ever somebuddy tries to open the inner folder he/she will get the “Permission Error”.

You can do this trick on single folder or single file, but using two folders you can hide the actual file names too. Actually this is just a basic folder protection trick for Ubuntu, just replacement for Hidden attribute in Windows OS.
