When should I upload in binary or ASCII mode?
Binary mode and ASCII mode refer to two ways an FTP program can transmit files. Certain kinds of files are better suited to each mode.
Fortunately, most FTP tools include a third mode: an "auto" or automatic option, which decides for you which mode to use when uploading a file, so you don't have to think about it.
If your tool does not include this option, you can decide which mode to use based on these guidelines:
- Use ASCII mode for files that contain all text (such as HTML or text files).
- Use binary mode for images and other media files, such as videos.
NOTE: As of February 19, 2013, Yahoo Small Business has completed the transition from supporting FTP to FTPS. To avoid any connection issues, please make sure you have updated your FTP client to use your FTPS settings.
