How can i change the permission of root files or looked files ?
 

I had used test desk program to restore my files ,
the files that recovered was saved in home folder ,
the problem is that these files are become root permission only ,so i cant
copy , move theme .

So anyone thankfully explain how can i change the permission of these files

I ran into something like this not too long ago.

The first and most important command you are looking for is chown.
You are going to want to change a lot of files at once so you will want to make that change recursive over the home directory it will look something like this:
I am using davdunc as both the user name and group name here because I expect you have "user-private groups".

Thanks man

GUI Method
 

log on as root, change the permissions of the file as root to whatever and then log on to user.
