Common Files

I was wondering if it's in any way 'unsafe' to keep files here. For example I use Audacity and keep the Lame/FFMPEG files here. But also it's a convenient place to keep other stuff like Sounds for certain apps like KkMenu, as well as Roms and VST collections. Rather than keep them in the Documents folder where they aren't ever really needed to be accessed directly puts them 'in the way.'

Currently I've created a directory called - Common Files - but would rather use the existing one if it's ok to do so.

Thanks
