This is the first version of the Hollow Knight Save Manager, ill try to update it and create a fresher looking app rather than this 2010 style app
Click the green "code" button and download the app, then run the .jar file to open the app
The app will create a settings file, so i recommend placing it in a new dierectory
Go to your Hollow Knight save directory (is usually something like this C:\Users\user\AppData\LocalLow\Team Cherry\Hollow Knight), copy the rute and paste it into the box "Select a directory", then hit save. I recommend relaunching the app after saving, it works fine but the names from the list does not copy into the box when an item list get selected.
Select a user from the list, each user represents a profile from the game. Then hit the save buttond.
Select a file from the list, select the user where you want to copy it and hit the load save button.
Select a file from the list, then hit the delete button.
Select a file from the list, change the name in the box and hit change save name
