Folders in Interface removed V8.1
 

32 removed with 8.1 : ACHIEVEMENTFRAME, ... .
But why?
Can I use the old folders from 8.0 or should I remove them?
Are the old folders no longer useful?

Answer please ;)

The folders were removed because they provided a sub standard skin, and just served to mask that fact. Additionally, many textures were changed in 6.0 so those would have looked buggy.

Are u going to update them for WoD or the latest Patch?

no, they will not be updated.

Is there a link to these texture replacements? I dont remember when I obtained all of mine inside the interface folder (actually have been wondering where for a week now) but I guess they came with RealUI at some point or something?

There is MiirGui Texture Pack and Aurora: Missing Textures and an outdated version of AI-Art. Thats all texture replacements packs I know...
You may only use the texturs you need :)

Ooh! It was the aurora missing textures! Thank you so much! Finally updated it :)

Also, the old 8.0 version of RealUI is still archived in the Other Files tab. This will still have the replacement textures.
