Platform limits on files

Note:

There are platforms that limit the size of files that they can read. For example, a 32-bit operating system typically has a smaller addressable memory than a comparable 64-bit operating system and consequently limits the size of a file there.

If you have created a problem file on one platform, and you find that you are unable to read the problem on another platform, consider whether the platform where you are trying to read the file suffers from such a limit on file size. IBM ILOG CPLEX may be unable to open your problem file due to the size of the file being greater than the platform limit.
