32-bit 2Gb file limitations

Nov 14, 2011 at 3:41 PM

I am not sure how they do it, but in one of my GIS applications, their internal files are able to be used to any size. I once had an native image file of 100Gb. This could be very advantageous, but probably not too worthwhile to be a high priority presently. Something to think of though.

What file format was that image? ECW perhaps?

We'll add this to the TODO list as well.

Do you still have access to that 100GB file for testing?

Hi Paul

It is the internal file format of Microimages. It really is something interesting as any vector/raster can be any size up to the limit of the hard disk (i think as i have never gone that high before).

I don't have that specific file anymore, however I can always create one again if need be. It is an rvc internal file format which i assume they have written.
