How can I identify (and delete) tracks already played?

You need to create a tagnavi_custom.config file to create a custom search in the database. Check the wiki, can't tell you off the top of my head how it works (and have a look at the default tagnavi.config)

DrRemulak:
Hmmm.... well I thought I was able to successfully create the custom tagnavi but it didn't work.

I created the file similar to what's listed here for Example 3:
http://www.rockbox.org/twiki/bin/view/Main/DataBase#Examples

However, I don't think the runtime stats are ever getting updated on my player.  I did enable 'Gather Runtime Data' in the database settings but maybe I'm missing something else. 

The reasons why I don't think the runtime stats are being updated
1. The 'Recently Played Tracks' view (which is already in Rockbox, not something I created) doesn't show anything even after I play a few tracks.
2. I tried to backup the runtime stats by performing Export Modifications in the Database settings menu.  It created a small file with no stat data in it.

Any ideas why the runtime stats are not being updated?

Thanks.

You may need to restart your player (or at least wait until a re-buffer has happened), in order to ensure that the data has been committed to the database.

Tried those.  No change.  Not sure why I can't see runtime updates. 

EDIT1: OK, I tried again and now it's working.  The only thing did differently was to take it out of shuffle mode.  Maybe that was the issue.  Will try again later.

I created the playlist of tracks that had been played and saved it as an m3u file.  Then I edited it to be a batch file to delete the tracks.  It worked!  I will probably write an AutoIt script to automate the process of deleting the files once the playlist file has been created. 

Thanks!

EDIT2: Here's the AutoIt script to delete files from a playlist generated by Rockbox:
--- Code: ---;Delete already played files by using playlist generated by Rockbox
;
$message="Choose playlist file containing tracks to be deleted"
$var = FileOpenDialog($message,@ScriptDir,"All (*.*)", 1)
If @error Then
    MsgBox(4096,"","No File(s) chosen")
    Exit
EndIf
$file = FileOpen($var, 0)
; Check if file opened for reading OK
If $file = -1 Then
    MsgBox(0, "Error", "Unable to open file.")
    Exit
EndIf
Global $microdir = ""
While 1
    $line = FileReadLine($file)
    If @error = -1 Then ExitLoop
    $line = StringReplace($line, "/", "\")
$microchk = StringLeft($line,12)
if StringCompare($microchk,"\<microSD1>\")=0 then
  $line = StringTrimLeft($line,12)
  if StringLen($microdir)=0 then
    $microdir=FileSelectFolder("Choose drive folder containing microSD1 card.","")
  endif
  $line = $microdir & $line
endif
    If FileExists($line) then
       FileDelete($line)
    else
       MsgBox(4096,"",$line & " does not exist")
    endif
Wend
FileClose($file)
$answer = MsgBox(4,"Delete?","Delete playlist file?",20)
if $answer=6 then
   FileDelete($var)
endif

--- End code ---

EDIT 3: Modified script to delete files from microSD card.  Obviously the card has to be out of the player and inserted as a drive on your PC (e.g. via USB adapter.)

Also note that you must use AutoIt 3.2.4.0 or greater because of UTF-8 support.  Rockbox saves the playlist in UTF-8 format and previous versions of AutoIt would only use ANSI, thus choking on the playlist text.
