File systems on different operating systems can use different size addressing. Most current file systems use 32-bit or 64-bit addressing. The operating systems/file systems using these two sizes are listed in the links below.
The File Handler is configured to work with either 32-bit or 64-bit addressing by setting the FILEMAXSIZE configuration option. It is vital that all applications sharing a file use a File Handler that is configured in the same way, otherwise data corruption can occur.
You can configure the File Handler to use 32-bit addressing in a file system that uses 64-bit addressing. In this case, all files will be safely limited in size (to 32-bit addressing) by the File Handler.
