3DES

Archived as of 24/08/18

A (simple) homebrew 3ds File Browser written in C

• Top screen - main file Browser
• Upper area of bottom screen - instructions
• Lower area of bottom screen - debug output (look here if, for example, you try to create a directory and nothing happens)

Buttons:

• A - Change to selected directory / Open file context menu
• B - go "up" a directory / go back
• X - CD to /
• L - Create a new directory (brings a keyboard up to type the name)
• R - Delete file/directory
• DPAD/Circle pad up and down control the selection of files/directories
• DPAD/Circle pad left and right go to the top/bottom of the file/directory list
• START to close app and go back to HB menu

Warnings

• Deleting directories uses a recursive function, so if you have a large (very large) amount of subdirectories inside the directory you want to delete, it may end up breaking

Notes (mainly for myself)

Directory stuff | Using escape codes | Explanation of strtok()

• According to Wikipedia, the max FAT32 path length is 255 UTF-16 characters, so size of current_path = 255 * 2 = 510 (because the 16 in UTF-16 means 16 bits = 2 bytes)
• All malloc / realloc statements + arrays create the length needed +1, because there needs to be room for the end character

ToDo

• Finish context menu
  • Copy, Cut & Paste
  • Show file size
  • stat() info
• Add create dummy file option
• Add ability to view file hex / text
• Custom font / font-size (if possible?)
• Add ability to rename file / directory
• Add ability to mark files for multiple deletion and/or copying
• Look into accessing areas other than sdmc:/
