Various forums throughout the Internet have users stating that even though they’ve disabled media indexing the @eaDir folders are still being generated, and even outside the indexed folders.
In order to completely stop the generation of @eaDir folders, it’s necessary to disable the services that are generating them.
Note that after a DSM update, these services may be re-enabled.
To disable these services, log in to your Synology NAS via SSH, then do the following:
cd /usr/syno/etc.defaults/rc.d/ chmod 000 S66fileindexd.sh S66synoindexd.sh S77synomkthumbd.sh S88synomkflvd.sh S99iTunes.sh
After disabling the services, you may want to delete all the created @eaDir directories.
Any feedback on the above is welcome, please leave it in the comments section below. Thank you!
