When working on Cisco devices, sometimes you have to delete files from the device. It’s moreless the same on all Cisco devices. While there are other file systems available to you on your device (see first command listed), Cisco devices use “flash:” as their default file system. My examples will also use the default “flash:” but note that the commands will work the same on any other available file system, such as “usb0:“.
