reso is an AudioCoverArt object that provides the size property which returns a FileSize object. This object's fmt property looks useful.
Putting it all together: reso.size.fmt.

Note 
, I had already seen fmt in many scripts but I never thought it would make that big of a difference, grateful for more!
I can't believe it, the script is almost ready, now I just assign the functions to the buttons.
I would really like to understand how these events work, for example, I have a "btn_save" button, and the name of the dialog is "Mp3TagFile", what would the code be so that when I press the button, all the changes made in the dialog are saved?
if (msg.event == "click") {
switch (msg.control) {
case "btn_guardar": Mp3TagFile(dlg);
}
}It's not as quick as you might think... you need to read all the values from the object and write them to the file with SetAttr META.
I understood, I will work based on that.
Somebody help me please. How do I have to do so that, when clicking on a button with the name btn_guardar, the following command is applied?
cmd.RunCommand('SetAttr META "title:' + dlg.Control("titulo").label + '"');
if (msg.event == "click") {
switch (msg.control) {
case "btn_guardar": cmd.RunCommand('SetAttr META "title:' + dlg.Control("titulo").label + '"');
}
}
It is in the docs, topic: "Interacting with Dialog Controls"
Looks okay. If it's not working it's probably because FILE= is missing from the command.
Thanks @Xyzzy, but that example is in VBScript, different from JScript. I have searched a lot in the manual and in the forum but nothing applies at all, and on Google it is worse, a thousand different programming languages 
Thanks @lxp, so the code structure (syntax) is ok? That is the part that worries me the most, the one related to SetAttr META I understand better.
I'm going to try, hopefully it works:
cmd.RunCommand('SetAttr' + ' FILE="' + item + '"' + ' META "title:' + title_name + '"');
I continue to have problems with the buttons, they do not respond, I asked for help outside the forum and they told me that I should reevaluate the variable in the following line switch (msg.control) {, but I can't correct that, can someone help me?

The script is already starting to have life, weak breathing, but it is already breathing
When I run the script, all the modifications I make are saved correctly when I press the "Save" button, except those in the "Genre" field (Combobox), which sometimes saves the value "-1", other times "Jazz+Funk", etc
Regardless of whether I modify the "Gender" field or not, every time I press the "save" button, after saving the changes the following error is generated.
I would also like it if pressing the "btn_guardar" button would close the window; and that when pressing the buttons, "btn_eliminar_caratula" and "btn_eliminar_todo", their respective values will also be deleted in the window and not only in the file.
Try to see if you can help me with those things, for my mental health, I'm going to go crazy with this script
For genre you need to use
dlg.Control("genero").value.name
Please study Control to understand why this is different from the others.
This was some good advice, too good to ignore:

Don't think that what I don't achieve here is due to lack of study because I dedicate a lot of interest and effort to everything that you guide me or recommend, it's just that for me it is very difficult, they are two completely unknown languages, English and programming, apart from that we do not all have the same abilities.
Getting back to the topic, now the gender is set correctly, but when I open the file a second time, the gender displayed is not actually the one it has, but rather the first one in the list.
Could you also please show me how to remove the value of a text field from the window? Thank you so much.
Set the field to an empty string, e.g.:
dlg.Control("titulo").value = '';

Now I have the problem with the "btn_anadir_cover" button, it allows me to select a new cover, but immediately afterwards generates an error and restarts Opus.
case "btn_anadir_caratula":
var coverart_usuario = dlg.open("Carátula");
dlg.Control("caratula").label = coverart_usuario;
break;
And if I change dlg.Control("caratula").label = coverart_usuario;
for dlg.Control("caratula").label = Script.LoadImage(tmpFile);
The image is not updated, it always shows the old one, which is normal.
Try
dlg.Control("caratula").label = Script.LoadImage(coverart_usuario);
