As @s3m4ph0r3 points out, you’ll get FileNotFound exceptions from UPX if you cut and paste the the command shown in step 10. The problem is the quotes are not the ASCII ” character, but rather are the Unicode UTF character codes for “ and ” which are quotation-mark-left-double-reversed comma and quotation-mark-right-double comma respectively. The correct command is:

for %v in (*.exe *.dll components\*.dll plugins\*.dll) do upx "C:\Program Files\Mozilla Firefox\%v"

Using this got rid of all but one UPX error. The remain one was that it couldn’t compress one file. I thought that would be OK, but Firefox 3.6.6 would crash when starting afterwards.

I’m not going to purse this any further, but would suggest that you back up your “C:\Program Files\Mozilla Firefox” folder before trying this tip to make it easy to restore things if it doesn’t work for you…

@jad: In a nutshell, the command compresses the Windows executables and Dynamic Link Libraries in the current and listed subfolders using the UPX utility.

I believe the idea is that they will then all load faster because of their new smaller compressed file sizes.

i did not understand the meaning of ” for %v in (*.exe *.dll components\*.dll plugins\*.dll) do upx “C:\Program Files\Mozilla Firefox\%v” and hit Enter. ”
what do you mean by this?

I kept getting FileNotFoundExceptions.

I had to use the following command for it to work.

for %v in (*.exe *.dll components\*.dll plugins\*.dll) do upx C:\Progra~1\Mozill~1\%v
