The file browser is provided as a simple way to manage files on your DS. To cycle through available modes, tap the &l; or &r; buttons. When viewing hidden files is enabled, pressing &x; will hide or unhide the selected file. On applicable files, pressing &y; will perform the alternate action (viewable on the top screen).
The text editor currently supports .txt and .ini file editing, with syntax hilighting on .ini files.
The image viewer currently supports .bmp, .jpg, .gif, .png, and some .bin formats for raw NDS data viewing.
The sound player currently supports .wav, .mp3, .ogg, .pls (for streaming), and module files.
Naitive file launching is currently only supported on the GBAMP and SuperCard, although the MightyMax launcher does work on some other cards.
