Hi, all a shitty 3rd party software I cannot avoid using is stripping the metadata from a lot (but not all) of my files and I want to know if it's possible to re-write the stripped fields based on where they are located and their file name Example E:\Labels\Rekids\2021-01-29 - Immortal Daydream\04. Alan Fitzpatrick - The Underdog.aiff from the above, I can gather the following Label (Rekids) Year (2021-01-29) Album (Immortal Daydream) Number (04) Artist (Alan Fitzpatrick) Title (The Underdog) Is there a way of doing this? Thanks in advance Summy ---

Create an action using GUESS VALUE. The source should be PATH and the guessing pattern is > E:\Labels`\`%publisher%`\`%YEAR% - %album%`\`%track%. %artist% - %title%.mp3 There is no field for label, so I suggest publisher, but you can also use the comment or grouping field. If the _E:\Labels_ part of the path isn't static, you can use something like > %dummy1%`\`%dummy2%`\`%publisher%`\`%YEAR% - %album%`\`%track%. %artist% - %title%.mp3 ---

Fantastic! Thanks, I'll give it a crack ---

There should be a slash between %publisher% and %year%. ---

Is there a similar way I can introduce a file's catalogue number from its path? Path example \*\ANJ022R Super8 - Alba (Maor Levi Remix)\file Catalogue field ANJ022R ---

There is not a %catalogue% field, but you could use a guessing pattern to pick it up and put it into whatever field you want. ---

According to [https://wiki.hydrogenaud.io/index.php?title=Tag\_Mapping#Identifiers](https://wiki.hydrogenaud.io/index.php?title=Tag_Mapping#Identifiers) you could use CATALOGNUMBER or you follow this > [@Help me map Vorbis to ID3v2](https://community.mp3tag.de/t/help-me-map-vorbis-to-id3v2/13664/5): > > ID3v2 has special [TXXX](http://www.id3.org/id3v2.3.0#head-29e37534e169ad913deb6a4fee345028f3db7c3f) (user defined) fields, which allow you to have fields of any name. In Mp3tag, if a name doesn't map to one of its recognized four-letter frame names, then Mp3tag will create a TXXX frame with that description. So you can write things like 'Catalog #' or "Catalog Number'. This is commonly how ReplayGain fields are written to ID3v2 tags - TXXX frames with descriptions of REPLAYGAIN\_TRACK\_GAIN, REPLAYGAIN\_ALBUM\_GAIN, etc.. You can read the ID3v2.3 and 2.4 specs [here](http://www.id3.org/Developer_Information), but th… As @jewahe already told you, there is no standard field for CATALOG in ID3v2.3 or v2.4 It depends on your playing software, if it reads your choosen tag for the catalog content. ---

The Discogs Tag Source uses `CATALOGID` if you're already using that. To actually do that from the example, you'd the converter "Filename - Tag" with a formatstring like `%CATALOGID% %DUMMY%\%DUMMY%` Please note (also @jewahe), that there is no %dummy1% or %dummy2% field. You can reuse the %dummy% field for every part you want to ignore during import. ---
