Title: UNloading Map Data
Post by: KenF on November 11, 2007, 02:43:42 PM

Having used TF for quite some time I have accumulated LOTS of map data and am running low on space on the disk where I have it stored. There is much of that map data that I only used briefly and could happily delete. Is there any way to downsize the data files by selectively deleting/unloading only data that is no longer useful?
If not,  can I simply delete some of my .DAT files?

Right, I'm surprised no one has brought this up before, although these days disk space is pretty cheap.

There's no way (in the program) to delete downloaded maps.  You can't safely delete *some* of the .dat files either.  You can only start over fresh, which wouldn't be too bad idea since you could then use DXT1 compression for lower memory usage and faster map display.

I suppose you could imagine drawing a box over an area and asking it to remove all maps.  It's a possible feature addition.

Thanks.

Just as an observation of a way to avoid the situation I find myself in - I have occasionally changed the designated data path to a location that is only used temporarily.  After use,  the data path can be changed back to its original setting and the "temporary" data files deleted. Unfortunately, I have not been meticulous in doing that and have ended up with the excess data I now wish to remove (not really a huge amount).  

Oh well, reloading everything will not be that difficult, especially with the "load maps" function since I have some fairly well defined areas that I want to keep on hand.  

Thanks for pointing out the DXT1 compression option. I will give that a try since I sometimes get a bit frustrated with map display speed, especially when waiting for TF to catch up when I zoom in or out (using a mouse scroll wheel) and overshoot  the goal.

Wow! Using the compression option is great! It really tames the awkwardness of slow display when zooming.
