14/1/ · Image mode and Binary mode mean the same thing in FTP. This command tells the server that the transfer is going to involve a file with a binary data type and hence to prepare for a binary mode transfer. The download proceeds as before.

FTP Binary and ASCII Transfer Types And The Case of Corrupt Files
There are two different modes for transferring files with FTP: "ASCII" and ftp option binary mode. The reason for the two different modes is that there are two distinct means of representing the end of a line in a text, or ASCII, file. On UNIX machines, the end of a line is represented by the character. This character is a control-J. Ftp option binary example, if you have a UNIX file named "foo":, ftp option binary. This is a control-M followed by a control-J.
In FTP, if you specify "ASCII" mode, if you are sending a file from a UNIX system to a PC, ftp option binary, a control-M will be added before every control-J in the file.
Conversely, if you send a file in "ASCII" mode from a PC to a UNIX system, the combination control-M control-J will get changed into a control-J. File size will decrease by one byte per line when sending from a PC to a UNIX system; file size will increase by one byte per line when sending from a UNIX system to a PC.
When sending between two PCs -- or two UNIX systems -- files send in "ASCII" mode will be unchanged. Files sent in "binary" mode are sent from one system to another with no modification.
The file size will always be unchanged on a binary transfer, ftp option binary. If a binary file is sent between a PC and a UNIX system in "ASCII" mode, the contents of the binary file will be modified such that it will no longer be readable; the file will have to be re-sent from the originating system in binary mode.
Typically, this is the source of the problem when a customer sends us TAR or compressed files that are not readable on our machines. Additionally, everyone should remember that since our ftp site is an NT server, the default transfer mode is ascii. Our typical customer is a UNIX sys admin. Ftp option binary are used to sites that default to binary. When asking them to put files on our site, remind them that it defaults to ascii and that they will want to set binary mode.
