From the developer:
Tag Database Tool (TDT) is a replacement for the software provided by iRiver for creating the tag database file, iRivNavi.iDB, which is slow and only supports MP3 tags. TDT is much quicker and supports WMA, WAV (with ID3v1 tags), ASF and OGG files as well as MP3 (ID3v1 and ID3v2 tagged) files and also supports features to customise the database.
You may want to check out more software, such as StreamXpress, which might be similar to TDT.
