Could change Finder icon solution be problematic???

I was successful in changing my Finder icon!!! Now I just hope to confirm that the actions I followed will not be problematic down the road?
Going to upgrade to Snow Leopard (finally) and so if I get the green light I'll repeat this process after my erase and install.

The main reason I ask is because I am unaware of the content of the two files deleted. I just went for it. Were these files ok to delete?

From a post on AppleDiscussions by UtahMacTech, edited and tweaked for accuracy by myself, here are the actions taken:


Replace your finder.png:
Macintosh HD/System/Library/CoreServices/ (control click on) Dock/ (open) Show Package Contents/Resources/finder.png

From here I just edited my original .png file using Seashore (I pasted the image I wanted over it) but you could probably use any .png file. Name the new file "finder.png" drag it into the Resources folder, "do you want to replace existing file"? Yes

Then do the following:

1) While in Finder type: shift and command and g (for Go To Folder) and search for:
/private/var/folders/

open the first folder labeled "z7" (on my computer), open the next folder labeled something long and abstract, go to the "-Chaches-" folder and delete the file called:
com.apple.dock.iconcache

2) Delete "com.apple.dock.db" in your Home Folder/Library/Preferences.

3) Restart into safe mode by holding down the shift key during restart.

4) Empty trash after restart

5) Restart the computer as you normally would

 

Awesome! Thanks
