You might also try C:\Documents and Settings<username>\Application Data\ and C:\Documents and Settings<username>\Local Settings. A lot of applications use subdirectories based under one or both of those paths for data and cache.
The Google Desktop Search Engine is a program that lets you search for files on your local hard drive. It is MUCH faster than the built in search Windows comes with - on my machine, the search finishes faster than the Windows Search takes to find the first item.
And for the record, my index files are ~125MB, for about 150GB of stuff. Not bad.
Well, mine was 49 MB for 12 GB of data. But I think the type of data you have has a great effect on the index size. If I had 10 gig’s of MP3’s, they would take almost no index space, only the titles and possible ID3 info for each one. If I had 10 gigs of Word documents, however, I bet the index would be huge.
I just pulled that example out of the air, I don’t know which types of documents it even attempts to index, but the concept is valid.
Minor mistake in my disk size counting - I have a 100GB & 80GB drives in my computer, and am using 140Gb, but 20GB is in for my Linux partition. Windows can see about 120GB of stuff, with 35-40 or so gigs left open for Windows. I have a lot of .mp3 files & large movie files, that take up quite a bit of space but are easy to index, and not so many text documents. Google Desktop Search is reporting 37,824 searchable items.
