Saving folder size (where album is) and total album length

Hello!

I'm export my collection to Excel files as Album per line. I use tags like ARTIST, ALBUM, YEAR and so on. Is there a chance to export total folder size where the album is located? I know we have _FILE_SIZE tag. Is there any chance to create something like FOLDER_SIZE? :slight_smile: Or maybe there is a script that can count total size of directory where exporting files located?

The same thing with LENGTH tag, would be great to get TOTAL_LENGHT or something like this? :slight_smile: Is it possible?

Thank you in advance for your attention, guys!
