First, thanks for the wonderful software. I've been using it for a very long time.

Under Tag Panel's default values, we are presented with a scroll-down list of 3 choices: <blank>, <keep>, and <enter>.

Very often I name the file folders on my PC according to the album names. I suspect many people do the same. I wonder if you could add an additional choice of <folder> to the list, so that the folder name is used as one of the selectable values for the album tag.

After implementation, the scroll list would look something like:
<blank>
<keep>
<folder>
<enter>

For instance, if I have a list of mp3s inside this folder on my pc: c:\music\donald duck songs\
I could simply use <folder> as the tag for 'album', and 'donald duck songs' would be used as tag for the mp3s' album.

This is what the converter Filename - Tag is used for: just import the folder name to the album field by using a format string like
Kind regards,

Thanks! I didn't know that the filename-to-tag converter could be used to capture the folder name as well.
Wow, this opens a whole new world. I could load many folders, or subfolders, and easily convert them all at once!

Thanks again.

Hi,

Thanks, that helped me too.

But suppose the song is in a folder...

"H:\Entertainment\Songs\English\Avril Lavigne\The Best Damn Thing"

and I want the album tag to be like 'Avril Lavigne - The Best Damn Thing'

what should be the syntax then?

As the converter could not import a variable (like %album%) and a literal at the same time (which ist the hyphen in your example) you are stuck with a "format tag field" action.
If you can do without the hyphen, though, then the syntax would be:
%album%\%album%

But you should import artist and album separately with the mask
%artist%\%album%
and then format the tag field album:
Format tag field ALBUM
Format String: %artist% - %album%
