While compressing text files blank spaces are removed. In the compressed mode, since the data is compressed, there are many advantages to increasing the throughput. Main bytes include 16-bit values and 8-bit description subcodes.

The file is transferred as a block, and the block has its own 3-byte header. However, in case the file is divided into records EOR and EOF are required. There is no need to specify EOF while closing data. the data is divided into segments by TCP. Stream modeĭata is transmitted as a stream of bytes in the default settings of FTP. Transmission methodįTP transfer mode has 3 modes, namely streaming mode, block mode, and compressed mode. Random access or sequential access can be performed. The page structure file is divided into pages, each page has a page number and a page title. The structure record file is divided into records for text files and is marked with EDR at the end. Non-structured files are byte streams and are usually marked with EOF at the end. File organization and Data structuresīoth structured and nonstructured files can transfer via FTP. This will avoid double conversion from ASCII to EBCDIC and vice versa. As for EBCDIC transfer type, well it is recommended for exchanging files between systems that support EBCDIC. Binary files are programs and other non-text files saved in the format of the application that created them, or in the format of archived or compressed files. These files can be without extension or with a. There are two main types of files used when transferring files using the FTP protocol: ASCIIĪnd binary. Below we have gathered the main features of the FTP protocol. However, the list of its features covers more than that. The main purpose of the FTP protocol is to provide fast data transfer.
