Opening files from file-roller

[José Alburquerque <jaalburquerque yahoo com>]

Hi.  I'm presently running GNOME 2.8 on CentOS 4.3 (RHEL 4) (with great 
success, I might add :-) ).  I recently "reset" my user account by 
moving all the "dot" (or "hidden") files (.[^.]*) in my home directory 
into a backup directory and login in as a "new" user to allow all the 
applications to "regenerate" their dot-files.  (I did this because my 
account is extremely old and I thought it was about time I cleaned 
things up a little).

Before my reset whenever I ran "file-roller" I was able to right-click 
on any file, select "View" or "Open" from the menu and a list of 
"compatible" applications (which could open the file selected) would be 
shown for me to decide which one to use to "launch" the file (for 
"viewing" or "opening").  Now, after the reset, the application list in 
"file-roller" is empty.  Is there any way for me sort of "configure" 
file-roller to "know" which apps to use for which files?  Sorry if the 
question is obvious.  TIA.

Sincerely
Jose Alburquerque
