Set the FTP Transfer Type to Binary

Demonstrates the Chilkat Ftp2.SetTypeBinary method, which sets the FTP representation type to binary (TYPE I) for subsequent transfers. It takes no arguments.

Note: The local paths are relative to the application's current working directory. Absolute paths may also be used. Supply the paths appropriate to your own environment.

Background: Binary mode transfers bytes verbatim and is the correct choice for essentially every file, text included. Chilkat already defaults to binary, so no call is needed to use it — this method exists to switch back explicitly after a prior SetTypeAscii. The alternative ASCII mode applies line-ending translation that corrupts binary files, so binary is the safe default to keep in place.
