Files can be transferred in two different modes: ASCII or binary. Auto mode follows a predetermined rule and transfers selected file types in desired mode.
Always transfer pure text files, e. g. .txt, .html, .htm, .cgi, in ASCII mode.
WARNING: Transferring a binary file in ASCII mode may damage the file.
Always transfer image files, executable files or ZIP archives (.bmp, .jpg, .exe, .zip) in binary mode. Also use this mode for unknown file types, or such extensions not registered under Windows.
If Auto is activated: WISE-FTP checks whether the file extension is listed under Options: File Types.
If listed, file is transferred in ASCII mode.
If not listed or if file has no extension, file is transferred in binary mode.
If Auto is deactivated: File is transferred in desired mode (binary or ASCII).
