System Folders

RetroArch stores its data in several folders. Here are some that might be useful when working with DOSBox Pure:

System/BIOS

This folder contains system files. Place SoundFont files or ROM files for the Roland MT-32 here if you want to enable MIDI emulation. It also stores system disk images used by DBP for installing an operating system.

Configuration Files

This folder is where DBP saves its settings. It also stores game-specific configurations for DBP.

Save Files

This folder contains save data created by the games themselves.

If you run a game from an archive or disk image, archives with data written to the C: drive by the game will be created here. See also Save and Load.

Additionally, files with changes made to the C: drive will be saved here for an installed operating system if you use the Save Difference Per Content mode.

Save States

This folder stores game states saved through the RetroArch Save / Load State feature.

Cores

This folder contains emulator cores used by RetroArch (see Installing DOSBox Pure).

Video Shaders

A folder for additional shaders to enhance graphics.

File Browser

This folder is the default location RetroArch will open when you select Load Content. You can place game archives here.

The exact location of these folders depends on your device, operating system, and how RetroArch was installed.
You can check their locations under the Settings / Directory section, where you can also change their paths.

Once you’re familiar with system folders, you can proceed to configuring graphics in RetroArch.
