File Extent Size (lxtsiz, fxtsiz)

c-tree Plus V6.x files are limited to a file extension size of under 64KB. The lxtsiz member of the XCREblk structure can be used to define file extension sizes of up to 2 GB. lxtsiz is specified in bytes. The fxtsiz member specifies the first file extension size applied when the file is created and may be up to 2 GB. For example, to start a file with an initial size of 100 MB, and to have the file grow by an additional 10 MB as more space is required, use these values:

fxtsiz

100 * 1024 * 1024 = 104857600

lxtsiz

10 * 1024 * 1024 = 10485760
