Setting the Default File System

You can specify the file system or directory that the system uses as the default file system by using the cd filesystem: privileged EXEC command. You can set the default file system to omit the filesystem: argument from related commands. For example, for all privileged EXEC commands that have the optional filesystem: argument, the system uses the file system specified by the cd command.

By default, the default file system is flash:.

You can display the current default file system as specified by the cd command by using the pwd privileged EXEC command.
