Purpose

Chsize will alter/change the size of a file on the disk.

It can either expand (add to) the size of the file with hex 00's, or truncate (decrease) the size of the file.

If the file is truncated, truncated data is lost.


top

Operation

When expanding the size of the file, Chsize adds nulls (hex 00) to the file to establish the final requested size of the file.

When truncating the file, data at the end of the file is lost.

Options
