Why does the size of a file change after the file is uploaded through FTP on to an S series switch

For S series switches (except S1700 switches), the FTP protocol supports two file transfer formats: binary and ASCII. The ASCII format is used to transfer text files, and the binary format is used to transfer compressed files, databases, system software, and other program files. When the ASCII format is used, some content of files is automatically converted during file transfer. Therefore, the file size changes after it is uploaded to switches.
