Hi,

I don't use Gedit, however if you open a file in gedit and while it is open have a look in the directory to see if there are other copies of the file as follows;

Code:

[root@ekbit13 bin]# ls -l sergen*
-rwxr-xr-x. 1 sc386dm sc386dm 12800 Nov 18  2013 sergen.scr

As you can see the Inode numbers have changed, below is an actual example using the Bluefish editor.

Code:

[~/test] 
(10:34:01)-(sc386dm)-(685)-> touch testfile.txt

[~/test] 
(10:34:14)-(sc386dm)-(686)-> stat testfile.txt
  File: `testfile.txt'
  Size: 0         	Blocks: 0          IO Block: 4096   regular empty file

Hope that this helps.
