UltraTagger is a user-friendly tool that can be used to manage the tags found in MP3 files (ID3 v1 and v2), encode, decode, rename MP3s and more.

Here are some key features of "UltraTagger":

· Supports ID3 tags version 1.0, 1.1, 2.2, 2.3, 2.4
Note: v2.2 tags can only be removed, modified tags are saved in their current version when possible and new v2 tags are saved as v2.3. No support for encrypted and compressed v2 frames (almost never used). Can read unicode v2.3 and v2.4 tags.
· Get album details from freedb
Connect to a freedb server through the Internet to download tag information about a complete album of mp3s. Can retrieve artist and album names, number and title of each track, genre and album year. When this is done you can automatically save ID3 tags version 1, 2 or both.
· Rename files using tags
You can easily rename many files at once using any tag version. Choose one of the popular predefined formats or create your own.
· Guess tag fields
Automatically get missing fields from the file name using the specified format.
· Encode and Decode MP3s
Using the freeware LAME encoder, UltraTagger can produce high quality sound files.
· Save and Open playlists
Use playlists to open all their files at once and create new playlists, supports "m3u" and "pls" types.
· Generate file name when creating playlist
Automatically generate the file name of your new playlist using your own predefined format.

· Open folder
Recursively open all files under a certain folder.
· Edit multiple tags
By selecting many files you can change some or all tag fields for all of them.
· Play files
Listen to open files using the built-in player.
· Capitalize tag fields and file names
Quickly change song title, artist and album name to title case (the first letter of each word capitalized) or rename files in lower case, upper case, title case and sentence case.
· Remove tags
Delete all tags in multiple files without effort.
· MPEG file information
View information like bitrate, mpeg version, frequency, mode, etc.

Using the menu you can copy a whole tag version and paste it in another file or the other tag version.
