I got movies that have folder name extras, this contains extra content movie files.

e.g.
Forrest Gump/extras
Shrek/extras


How can I prevent Kodi from automatically scanning certain folders in each movie folder
and adding it to the library?

is there a way to add some sort of $ sign to the folder name?
like the way we can prevent some folders in a shared folder from being seen on a network?

e.g
Forrest Gump/extras$
Shrek/extras$

I'm not at my HTPC to confirm the process, but according to the wiki yes it is possible. Check out set and scan content. If I had to guess, you'll have to go through Files mode and set the exclusion for each folder manually.

If you want an automated mode, then I don't know.

Good luck.

There's an add-on that does this for you, search out VideoExtras from the repository and set the exclusion folder to 'extras' without capitals. If you don't want to run the add-on (very useful I might add) you can use your advancedsettings to add something like this in your video section.

<video>
<!-- VideoExtras: Section Start -->
<excludefromscan action="append">
<regexp>/extras/</regexp>
<regexp>[\\/]extras[\\/]</regexp>
</excludefromscan>
<excludetvshowsfromscan action="append">
<regexp>/extras/</regexp>
<regexp>[\\/]extras[\\/]</regexp>
</excludetvshowsfromscan>
<!-- VideoExtras: Section End -->
</video>
