This action reads from a binary file to a variable, or writes from a variable to a binary
file. If you write to the file, the existing information in the file is not moved, it is
overwritten.
This action does not support reading or writing non-ASCII characters (characters with
codes above 127).
Note
When a WiseScript is called by a Windows Installer installation, the Windows Installer
installation does not recognize changes that the WiseScript makes to the destination
computer and will not uninstall them. Therefore, you must provide a way to uninstall or
repair such changes. See Uninstalling Changes Made by a WiseScript in the Windows
Installer Editor Help.
