This is such a computer specific issue that I have hesitated to ask, but maybe it is a more general question than I realize.
After 4 years in this job I have accumulated 260,000 cached Google Earth .png tiles covering my county. That amounts to 45GB of images in one folder. Statistically those files account for 23% of all files on my computer. In that time Google Earth has posted 2 different sets of tiles, so these are doubling up on each other. Also in that time we have changed from dial-up Internet speeds to a fiber optic connection with 30Mbps download. When I launch or save a Manifold 8 file, it seems to spend a long time "Analyzing image files." Is it analyzing these .png files? Today it took over an hour to open a 239GB file. Once it is up and running all seems fine. What might happen if I deleted the cache of .pngs and changed to not cacheing the tiles? Would M8 load faster?
I'm thinking of deleting the cache of .png files and either starting over or changing the setting so as to not cache data between sessions. Before I do anything rash, like delete these .png files, are there other ways to speed things up? I seem to remember something about having one folder with thousands and thousands of files could slow your computer, but it also seems to me that that problem has been overcome.
Again I realize the problem could be very specific to this computer, but if it is not, then I'm exploring alternative solutions for speeding up M8.
