I have a recently bought a NAS and am in the process of transferring my photo collection onto it. I probably have over 300GB of pictures (many in various RAW formats). At the moment these are just organized in “old fashioned” file structures but I have am hoping to improve this to a some sort of cross referenced tagging system. So far though I am running into a few problems and any help would be appreciated. I have tried using the following software:


Windows photo gallery - and this appears to rapidly retrieve photos from the NAS based on chose tag words. The main down side that I have found so far is that the windows camera codec does not yet support my S95 RAW files and so they are not visible. 
Picasa – this looks as though it might work well on a local drive (and certainly get good reviews) but I am finding it very slow when scanning the photo library on the NAS (even when left for a number of hours the scan in only approx. 5% complete!). I can live with a bit of a delay when using the NAS but this is unworkable - am I getting something wrong?
Various other photo viewers - Although they allow me to see my RAW files do not appear to support tagging and the development of a cross referenced library. 


I am also considering looking at getting Lightroom but don’t want to shell out the money only to find it is as slow as Picasa.

Finally, my ideal would be to have different layers of tags so for example I could tag all my pictures from the “Lake District” but then also have the option of sub dividing within this category based on the valley etc. Without different levels of tagging I risk winding up with an unwieldy list of tag words. I do not know if this is possible/normal but if anyone has any points about what software packages support this arrangement that would also be appreciated. 


Question: Doing túró at home
Answer: yes it is definitely a way because we are also doing at home.
In my interpretation there are two kind of túró. One is created from milk, this one tastes sweet. The another is created from sheep cheese, and this one is a bit spicy. The second one is traditional food of székely's.  In which one you are interrested?

Update.

Ok, here you go, I asked my girlfriend about how to do both:)

The sweet turó from cow milk(this one for túró rudi and for túrósgombóc).


You have to let the milk for 2-3 days in a warm area, to get acided. 
After that you have to collect the stuff from the top of it.    
Then you put the rest to slow fire and warm it  a bit, not too much.
Then you filter the content from the water.   
Done.


2 Spicy Túró (for túróscsúsza)

For this one you have to get sheep cheese.


You have to cut it to small cubes. 
Then put it into very salty water for a few hours.
Then you have to blend it with flesh bender.
Done.


Hope you will make it very tasty:) Good luck.
