From GameBrew

CTRXplorer is an open source SD file manager for the 3DS. Its design is based around the UI functions of the ctrcommon library by Steveice10. So, if you have been a FBI user in the past, it may look familiar to you. It's goal is to be a simple, functional tool for managing your files without any unneeded bloat.

Note from developer:

This is a fully capable file manager, and as such per definition a powerful tool. While its implementation tries to prevent you from accidental/reckless acts, it still assumes you know what you're doing. For example, nothing (except from a quick confirmation prompt) will prevent you from just deleting the Nintendo 3DS folder. While being thoroughly tested and in daily use by a number of users, please understand that the homebrew is not entirely bug-free and use it responsibly.


  • Delete single/mulitple files.
  • Rename files.
  • Copy single/multiple files.
  • Move single/multiple files.
  • Create directories.
  • Generate dummy files.
  • Display and edit files in a hex viewer.
  • Display files in a text viewer.



Available in CIA, 3DS and 3DSX formats.

  • 3DSX - Copy the CTRXplorer folder to the 3ds folder on your SD card and launch it via Homebrew Launcher.
  • CIA - Copy .cia to your SD card and install it with the CIA manager of your choice.
  • 3DS - Copy .3ds to your SD card.


Requires devkitARM and citrus to build. On Windows you will also need info-zip in your PATH.

User guide


Q. Why is copying files so slow?

The 3DS internal hardware doesn't allow for more speed.

Q. Why can't I receive/manage files via network?

ftBrony offers exactly that and it is unlikely that CTRXplorer will ever get any network functionality.

Q. Why can't I view videos and images and/or listen to audio?

An internal media player goes beyond the scope of CTRXplorer, which has the goal to be just a simple, no-bloat file manager.

If you absolutely must have media play capabilities, it is suggested to take a look at Sunshell.
