What it does:

This is a modified version of the same mod for Skyrim Special Edition.

• Runs a modified code of SKSE Co-Save Cleaner at the beginning, deleting excess f4se co-saves if they exist.
• Checks if everything is already backed up from the script
• Creates a "backup" folder along with "old" inside of it.
• Copies the *6 newest saves  to the "backup" folder.
• Deletes previous saves the "old" folder.
• Moves existing saves from the "backup" folder to the "old" folder.
• **It then DELETES the oldest saves until only the *6 newest remain in the main folder.

No data is lost, just moved around and copied.

**To disable that last bit just delete the last chunk, its all annotated.
*You could also change the max save numbers and whatnot to whatever, I just keep it lower

Installation:

Put all the files you download in C:\Users\Your Username\Documents\My Games\Fallout4\Saves

Optional Files:
Here's the readme from the optional file to see if you even wanna download it

Spoiler:  ShowThis script should be able to run from anywhere if properly configured.

I'd recommend leaving "AutoBackup.bat" and "FO4 Save Backuper-er.bat" In your FO4 save folder
for the least amount of file editing

If you keep "FO4 Save Backuper-er.bat" in another folder than your save folder you will have to edit the path in "AutoBackup.bat"
under "rem Run the batch file" to match the location of "FO4 Save Backuper-er.bat"

for example:

    rem Run the batch file
    call "C:\Users\YourUsername\Downloads\FO4 Save Backuper-er.bat"

    OR (My Choice)

    rem Run the batch file
    call "%HOMEDRIVE%%HOMEPATH%\Documents\My Games\Fallout4\Saves\FO4 Save Backuper-er.bat"

I keep "AutoBackup.bat" in my FO4 save folder and use "F4SE+AutoBackup.bat" to open FO4, then the script
keeping it 100% automated and simple.
If you want to use that too youd have to edit the F4SE launcher path and the path to "Autobackup.bat"
