I followed the wonderful advice in the Everything FAQ about "set "Everything" to use an external file manager". I have succeeded on 3 machines. I simply did what it told me which was
Add the following 2 lines to the bottom of the ini:
open_folder_command=$exec("ExternalFileManager.exe" "%1")
open_folder_path_command=$exec("ExternalFileManager.exe" "$parent(%1)")
However on my newest machine I just cannot get the edits to stick. Everytime I open everything it reverts to the original everything.ini and my edits are lost.
My system
Windows 7 64bit and I am an administrator
