thx for the answer
I've organised my music by artists folder in which i put all the music (don't really care about album information)
Picardz & lastfm plugins allowed for really nice information tagging.
Now my idea is to use Windows NTFS hardlinking capabilities to duplicate all this music in other folders by genre, décades, genre deacdes, décades genre and in each folder two subfolder with files named as title - artist & artist title.
So ultimately i'lle be allowed to browse generic search criteria from "basic" Windows folder structure to easily fill any mp3 player queue list.
Using hardlinking even if the files appear 5 or 20 times in different subfolder it's still using the same disk space as was occupied originnally.
The "batch" is to recreate all the criteria folders structure easily once in a while from original artist/file when i've added some new files (copying files wouldn't create hard link)
Well i must say that first tests were working lie a charm I join the script if you want to have a look.
Then i realised that using the "main" genre was quite limitating and was wondering if i could add main_genre & full_genre folders with tests like:
$ifgreater($strstr(%genre%,'Rock'),0,mklink /h "C:\antoine\tst_mp3\tri\tris\Rock_full\Titre - Artiste\%title% - %artistsort%.%_extension%" "%_folderpath%%_filename_ext%",)
for that either I browse all files with each "genre" test or I find a way to work all genre as I'm looking at a file.
Well sorry was a bit long.
Anyhow i've found a workaround, I just use mp3tag export habilities to browse all genre &... to create a mp3tag export mte file with all the hardlinking I want.
So workaround found don't bother
and thx for the support, mp3tag is really helpfull for batch processing/conversions.
