MC automatically imports any embedded tags it finds in the files. It also imports metadata information in MPL files and the special JRSidecar.xml files it makes for video files.
If you want to make it import metadata from directory and filename structure, there are two options:
1. Use the
Right-Click > Library Tools > Fill Properties from Filename tool. This requires you to select the files, but you can do large batches at a time. This tool is powerful and flexible, but is manual. It is best suited to get "large groups" of files situated (where once you are done, you are done).
2. If you want to add rules that are applied by folder that happen automatically at import-time, you can use the
Tag On Import system. You can certainly add rules, similar to those in the Fill Properties from Filename tool, automatically parse a strict directory and filename structure. Details are in the thread linked above.
Keep in mind, that MC itself can organize the files. Once you get your initial import done, you may find it faster and easier to just import everything into one central "junk" directory (mine is M:\Incoming\) and use the tools in MC to get the files tagged, and then push them to their "final destination" using the
Right-Click > Library Tools > Rename, Move, and Copy tool.
MC can handle the meticulous task of organizing the files into those subdirectory structures. You don't have to do it manually. The best use for Tag On Import rules is to automatically recognize structures that are pre-defined and automated in an external application that downloads or creates the files.
