There is a copy to clipboard action in action chains plugin. It allows you to define a template to determine what metadata to copy to clipboard for selected books. For example, if you want to copy the path (containing folder) of selected books, use the following template:
Code:
program:
paths = formats_paths();
fmt_path = re(paths, ',[A-Z0-9_]+:.*', '');
path = list_item(fmt_path, 1, ':');
dir_path = re(path, '(.+)[/\\].*', '\1')
Note: I tried the above on linux, have not tested it on Windows.
Or, if you want the path to a specific format e.g. epub, use this
Code:
program: select(formats_paths(),'EPUB')
