Decompressing ESM/ESP

Decompressing plugins.txt

Editing master files is generally dangerous so proceed with caution, i won't be responsible for your broken games and load orders.

1. Back up your plugins in case something goes wrong
3. Run FNVEdit with -AllowMasterFilesEdit -IKnowWhatImDoing -IKnowIllBreakMyGameWithThis arguments
4. In Module Selection window, load everything from your load order
5. When FNVEdit finishes loading, press Ctrl+A in the left window
6. Click right mouse button - apply script
7. Select new script in the dropdown, paste the script below in the window and click OK
8. Press Ctrl+S to save decompressed plugins when it finishes applying the script
9. Close the program

This should help with loading times and cell loading stutter as decompression is the most performance intensive part of 
loading.
