The original script was taken from the forum and I added comments and tweaked the script a bit.

1. Create a new folder Macros in EmEditor installation folder (C:\Program Files\EmEditor\Macros)
2. Download the macro file and put it into the folder
3. In EmEditor, select menu Macros -> Customize...
4. Select New and choose the macro file
5. Select the macro and select Runs at Events
6. Select Events... and then select Before Saving
7. All done!
