File manager - portapack-mayhem/mayhem-firmware GitHub Wiki

Used to manage files on the SD Card.

Controls

  • Use the encoder or up and down buttons to move between items.
  • Use the select (center) key enter a folder or to select an item to take an action on.
  • Use the right button to select a folder to take an action on (e.g. rename a folder).
  • Use the left button or select the ".." folder to go up a directory.
  • click on "-->" to get to next page, you will generally find it at the bottom of the list
  • click on "<--" to get to previous page, you will generally find it at the top the list

A small, blinking arrow on the right indicates that there are more items if you scroll down.

Pagination

When there are too much elements, the sorting is disabled (not enough memory to do it) but the pagination is turning on, allowing to view a lot more elements.

On pagination buttons lines and in place of the size, there will be a page number indicating to which page you will be going.

File type handlers

Selecting certain types of files launch a viewer for the content. Use the right button to enter the toolbar for these file types. Exiting the viewer when launched this way will return back to Fileman.

  • BMP files will open in the Splash viewer. If the file is of the correct size and type, it can be set as the splash screen.
  • TXT files will open in Notepad
  • PPL and C8 and C16 files will open in Replay in the correct mode.
  • PNG file will open the Screenshot viewer (this can only view screenshots generated on the device). When viewing a screenshot, press any key to return back to Fileman.

Known Issues

  • items are listed unsorted after a fixed number of element (hardware limitation, no enough memory to sort all the files).
  • Copy & Paste does not work on folders. (Note that Cut & Paste is now supported on folders.)
  • Folders must be empty in order to be deleted (use the Clean button to empty a folder first).
  • Cut/Copy/Paste does not work with "partner" files.

Tip: Use the SD-over-USB utility for more advanced file and folder editing via an attached computer.
