You should always have large files enabled for your database. Large file support allows you to support extent sizes in excess of 2 gigabyte (GB), up to a maximum size of 1 terabyte (TB), provided that the operating system supports large files. On UNIX, you need to enable operating system support for large files on each file system where the database resides. In Windows, a file can fill the entire volume. By default, large file support is enabled for all databases created in OpenEdge 12.0 under Enterprise license. All databases created in OpenEdge 12.0 under sub-Enterprise license will have large file support disabled by default.
