What are ID3 tags?
Because of the huge success of MP3s, it needed ID3v1 and ID3v2 tags are standard ways of embedding additional information directly in an MP3 file.
The descriptive information is known as a ID3 "tag". Dapyx MP3 Explorer will read that information (if available) when it builds the database.
The ID3v1 tag
consists of Artist/Album/Title/Category & Track number only. In addition, the maximum length of any of the fields is 30 characters (the entire tag is only 128 bytes long). This makes the ID3v1 tag a bit of a pain to use, but it is very fast.
The ID3v2 tags let you enter a lot more information, but only a few programs support them and it is also a little bit slower.
Dapyx MP3 Explorer fully support the ID3V2 to read and write. Because ID3v2 can provide more information than ID3v1, Dapyx MP3 Explorer assumes that ID3v2 will provide better information than ID3v1 -- but there are a few cases where people (or auto-taggers) have entered more complete information into ID3v1 but kept an ID3v2 tag with limited information.
