Re: [Easytag-mailing] copying on save

["Jérôme COUDERC" <couderj agf fr>]

Hi,

I've got the same behaviour when I add an ID3V2 tag at the beginning of the
file: the number of  inodes changes. This occurs also when you add more data
to the id3v2 (more than padding), because audio data are moved in the file.

But the problem comes from id3lib which manage the writing of the tag. I
don't know exactly how it works to add data at the beginning of the file,
but I suppose that it creates a new file, writes id3v2 tag, copies audio
data from the initial file to the new one, and then deletes the older
file...

Moreover you can test it with the program id3tag (supplied into id3lib
package after compilation). You will get the problem...

I recommend you to post a message into the mailing list
id3lib-devel lists sourceforge net to report the problem with hard links.

If this problem disturbs you, can can into desactivate the writing of id3v2
tag into EasyTAG. But before to create links, the initial files musn't
contain id3v2 data, else you will get the same problem.

Sincerely,
Jerome
