Performing batch operations
A batch file comprises a set of executable commands. Executing a batch file is the same as executing the
commands one by one. However, execution of a batch file does not guarantee successful execution of
every command in the batch file. If a command has error settings or the conditions for executing the
command are not satisfied, the system skips this command.
You can edit a batch file on your PC, and then upload or download it to the device. If the extension of
the file is not .bat, use the rename command to change it to .bat.
