By default, the File Handler can handle files that are up to a maximum of 2 Gigabytes in size. However, if you need to create larger indexed files, you can set the IDXFORMAT parameter in the File Handler configuration file to 8 to create IDXFORMAT(8) files. These files comprise a single file (as opposed to the usual .idx and .dat files) and can be up to 32 Terabytes in size.
Many operating systems have a limit on file size. To enable you to create large files on these systems, a striping option is provided. Striping splits a large logical file into as many physical files as are required (up to a limit of 256).
