I am looking for a way to compare Folder A to Folder B in this way:
- For all files/subfolders in Folder A that are not in Folder B, copy them to Folder B
- For all files/subfolders in Folder B that are not in Folder A, delete them from Folder B

What I'm trying to do here is make it easier to copy my music from my computer to my phone's SD card. I am constantly adding and deleting music from my computer, and I want to be able to run a script that will just make the music on the SD card exactly the same as the music on my computer.

It takes a long time to copy the amount of music I have over, so I can't just delete all the music from the SD card and copy the whole music folder from my computer. Hence why I need a script which will actually compare the contents and only delete the files which I've deleted from my computer, and add the files I've added.

Does anyone have any ideas on how I would do something like this? Alternatively, does anyone know a way to do something like this without AutoHotKey?

It can be done in AutoHotkey, but I use and recommend FreeFileSync for things like that. Use Mirror sync option.

Another alternative is the freeware Allway Sync. It has simple UI yet powerful. It also has portable version.

I can recommend SyncBack, I use it for managing my backups. It has free version, easy to use and has lots of options for managing files.
