* Ubuntu Linux requires ExFAT packages to run on the ExFAT format Filing System. Operating System and File System Compatibility There are several software packages that allow Windows, Linux, Apple & Android to read different file system formats, but these are technical and some are complicated to set up, so for the purposes of ease of use we have kept this cross-compatibility guide to reflect the standard Operating Systems limitations (unless specifically annotated). Here is a simple chart showing the cross-compatibility of Operating Systems and File Systems as they come ‘Out Of The Box’. Each operating system has limits to what it can read and write to, in terms of compatibility. There are many operating systems (like Windows, Mac OS X and Linux) that use different ‘file systems’ that organise programs and the storage of data.
