I have been trying to imagine which part of the library management could beslow with file and directory approach. Yes, it would be slow if we load all the components at program start up. But we can use laziness mechanism which will load only necessary components (in tree style). Thousands of files problem could be overcome by better category. I'm sure we have to store thousants of file in a single directory with current category style. This category style is somethings that i don't like in eagle and, sorry but, even worse in kicad. By using category style (as i proposed) like many component distributors (farnell, rs, etc), browsing through the library can be easier especially for a beginner (I still remeber the day i used ideal opamp in the design and confused with the real component). Another situation where file could be slow is searching. This can also be overcome by indexing which should be simple.

This discussion also remind me something when i first switch from eagle. Atthe time, I did still work with kicad in eagle way. I converted all libraries and modules from eagle and tried to load them all with my first kicad project. This freezed kicad and took minutes (yes, minutes) for kicad to load on a dual core machine. Imagine when the size of libary in kicad grows tothe same quantity of eagle and the same library database is still used.

With pre-structured (what also have be done in database), the directory would not be that complicated. Syncronizing, merging, editing ,deleting ,creating inheritance and creating categories are simpler and version control can be applied to each component using availiable tools such as cvs or svn. I also can see a lot of benefits using file anddirectory instead of database.
