cannot open file
 

I used FC5,When I double click to a file ,the pop up/prompt tell
"Cannot display.....".
All file in my computer have the same problem

Please somebody help me...

Has it always been like this, or did something change?
What is the complete error message?
Try right-clicking on a file and selecting properties. Look for the part about permissions and tell us what you find.

Also, open a terminal and use "cd" and "ls" to move around and list files. See if you can open any files using "more" or "cat"

I dont make any change cause i m new in Linux OS.I used the default setting and try to gain myself to learn linux.

Let's say i save a file using text editor and save it at desktop.The file name "team".when i exit the text editor and try to open again by double click to the file,the prompt said "Couldn't display "/root/Desktop/team".

In properties(permission):
File group and File owner is set as root.
Owner,Group,Other---> all tick
special flags ----->all untick

Tq my myfriend

Have you tried viewing the file in a terminal? Also, you aren't using the root account all the time are you? It sort of sounds like you are.
