Large Data And Java Memory

Ranges can now handle huge files, the largest being raster files used to define habitats and to use as background maps.

64 bit operating systems can use essentially limitless amounts of computer memory. If you are running 64 bit Windows or Mac OS, you can run Ranges so that it also has access to the huge amounts of memory that your state-of-the-art computer has.

The Ranges fatch file

The Ranges batch file (<Ranges installation folder>\ranges.bat) can be tweaked to run Ranges with any amount of memory less than that installed in you computer. Open this file in a plain text editor such as notepad to see the following:

<code>

::ranges-largememory.bat : starts up java GUI with DOS command window
::adjust the -Xmx setting to run Ranges with more RAM if your computer has it
::
::e.g. to run Ranges with 4GB of memory use
::
::java -Xmx4096m -jar ranges.jar 
::
::note that the maximum available to 32 bit Windows operating systems is about 1.4GB

java -Xmx1024m -jar ranges.jar 

exit
