Dealing with VERY large numbers

BlitzPlus Forums/BlitzPlus Programming/Dealing with VERY large numbers

I'm trying to create an application to find the sizes of various files/folders to display a pie chart showing a percentage of space that each file/folder is using. The problem is that when adding up file sizes (especially large video files) the byte sizes can go out of the range of BlitzPlus integers. Does anyone have a way around this problem? I'm sure there is another way of handling this. Thanks.
