Map1.dat
« on: March 31, 2006, 10:51:16 AM »
maps1.dat  This file has gotten very very large on my system.  It takes a long long time to back up.  What would happen if I lost it?  Why is it sooo big?  Right now it is at 364 MEG.  Is it my system?  It has been compressing to back up for over 5minutes now.  It seems that this has only started recently. I have V2.80 but it certainly could have started earlier.  Thanks

Mine is over 250 meg. I have 4 continents worth of maps/landsat in it. Since it stores the tiles from everywhere you have been, that is understandable. I think if you lost it you would have to re-download when you bring up the various maps. Your GPX files are separate, so you would not loose the actual data you ave collected in the form of GPS tracks. I don't backup my program files directory, which is where the maps1.dat resides, (mine is actually maps0.dat - not sure why), since this information is recoverable off the internet. My GPX files are kept in a directory I do back up.

mapsX.dat files store maps downloaded from Terraserver or OnEarth.  They will continually get larger the more areas you look at.

They roll over into ~650 meg chunks.  So it starts at maps0.dat.

You can delete the file(s) with no loss in functionality, you'll just have to re-download all your maps.  Be sure to also delete the file "mapindex.dat" which stores all the pointers into the mapsX.dat files.
