Max File Size Limit (mxfilzhw, mxfilzlw)

The mxfilzhw and mxfilzlw members of the XCREblk structure permit a maximum file size limit to be specified for a 4-byte or 8-byte file. The file size is specified in bytes.

• For files over 4 GB, mxfilzhw must be a non-zero value.
• For each multiple of 4 GB, add one to the mxfilzhw member.

For example, to limit the file size to 8 GB, set the (mxfilzhw, mxfilzlw) pair to (2, 0). To limit the size to 8.5 GB, use the pair of values (2, 2147483648). To indicate no file size limit, set both values to zero.
