No, you are right. Logasm tell Networker no matter is this file open or
not ie other program add or remove content to the particular file.

This message file size changed is Linux/Unix machines way to tell "I
cannot backup openfile in right manner" It's not may be consistent. In
Linux/Unix Networker take backup from opne files it's first check size,
backup and check size again, if same backup is consistent, if different
backup isn't consisntent. It means if this file is important you should
backup it again.

In Windows Networker refused take backup a openfile without Module for
Windows Applications.
