I read a number of threads with great suggestions on how to free up memory by deleting unnecessary files. However, I'm having a hard time locating the .cod files that I'd like to delete or BlackBerry.alx to edit.

When I go to... C:\Program Files\Common Files\Research in Motion I have 5 folders, but none called "Shared" or subfolders called "Loader Files" or "Java" where the .cod files are supposed to be. The only folders I have are AppLoader, BBBI Drivers, Modem Drivers, RIMDeviceManager, USB Drivers.

I'm sure I did something wrong, but no clue what it is. I installed the Desktop Manager that came with my 8130. And I downloaded the OS to my PC from this site: BlackBerry® Software Updates

I have done what I can to clear memory from the device itself without using my PC, but I'm still looking to free up additional space. Any help would be appreciated.

This thread does a great job of step by step removing files to freeup memory. one thing though, make sure you backup your device AND any cod files you want to remove just in case

Here's what my folder is called:
C:\Program Files\Common Files\Research In Motion\Shared\Loader Files\8820-v4.2.2.169_P2.4.0.67\Java

Try using the Windows Search facility and look for: net_rim_bb*.cod

I forgot to mention in my original post that I referred to these instructions, but somehow still ended up with the result that I described.

"Search is complete. There are no results to display."

Grrr.

Do you have Desktop Manager installed?

Yes, I installed this from the CD that came with my BlackBerry.

I just realized I have the same problem on my PC. I did the initial install on my pc and cannot find the shared folder or any of the others. But on my laptop I downloaded and installed the 4.3 OS. My laptop has the shared folder and the rest of them and thats where all the files are at.
So the only thing I can think of is something happened when you installed the OS to your PC and it didnt work. Try installing the OS again and see if it works.

When the "Shared" folder is missing that usually means that the Device Software (OS) has not been installed to the PC.
