Which command displays the files saved in flash memory along with their sizes?

The command "show flash" is specifically designed to display the contents of the flash memory in a Cisco device. When this command is executed, it provides a list of files stored in flash memory, along with important details such as the size of each file. This information is crucial for understanding the storage capacity and organization within the device.

By using "show flash," administrators can effectively manage the files stored on the device, check for available space, and determine whether new images or files can be added. This command is fundamental in network device management, especially when updating the IOS or storing configurations.

Other commands do not provide the required output. For instance, "show files" is not a recognized command in the context of displaying flash memory contents. Similarly, "display flash" is not a valid command in Cisco IOS, and "show memory" pertains to the overall memory statistics of the device rather than specifically targeting the flash memory files. The unique capability of "show flash" to retrieve detailed information about flash memory files makes it the correct choice for this question.
