Do group actions tag as they go, or only at the end?

[ohrenkino]

There is no variable called

@ehead

FOLDER_NAME

of if you use it, then it is a user-defined one.
Which would also mean that the file itself has to be touched each time as the variable is sought in the tag data.
And then it could be that the tag data has to be re-written as the padding is not big enought.

If you really refer to the variable %_directory% which references the current folder name then this is a call of OS functions which really only manipulates the folder name - and that should be done fairly quickly.

Also, see here:

Format Directory than Format Filename

Using format directory to move files to new location, than trying to create Disc Folders using format filename in the newly created directory location however: Format Directory - moves folder to new location Format Filename - generates Disc folders but pulls files back to original location to do so? Why is that and how can I achieve my end result without having to pull the new directory folder into MP3tag and than run the format filename?
