The difference between SecureCRT and SshClient in linux and windows is that SecureCRT does not have a graphical file transfer tool, but does not affect it. If you use commands to implement SecureCRT, it will be much easier and faster. Method 1: to upload a file, you only need to enter the command "rz" in the shell terminal simulator to select a file on the local disk from the pop-up dialog box and use Zmodem to upload the file to the current path of the server. To download a file, you only need to enter the command "sz file name" in the shell terminal simulator to use Zmodem to download the file to a local directory. You can use "File Transfer" to modify the default download path to your local device. Set the default directory: options --> session options --> file transfer. Method 2: Use sftpsecurecrt to press ALT + P to start a new session for ftp operations. Enter the "help" command to display all commands provided by the FTP: query the directory of the linux host (that is, the remote host directory) lpwd: query the local directory (generally the directory of files uploaded by windows: we can view the "session options" in the "option" drop-down box, and we know that the local upload directory is: D:/My Documents) ls: query which files are stored in the directory of the current linux host lls: query which files are stored in the current local upload directory LCD: change the path of the local upload directory cd: Change the remote upload directory get: download files from the remote directory to the local directory put: upload files from the local directory to the remote host (linux) quit: disconnect the FTP connection
