Class
C flash file systems. For more details on supported flash file systems, see Using
CompactFlash Memory Cards.

Step 3 dir flash:
Use this command to display the layout and contents of flash memory:
Router# dir flash:
Flash CompactFlash directory:
File Length Name/status
1 6458208 c38xx-i-mz.tmp [deleted]
2 6458208 c38xx-i-mz
[12916544 bytes used, 3139776 available, 16056320 total]
15680K bytes of ATA CompactFlash (Read/Write)
Step 4 From the displayed output of the dir flash: command, compare the number of bytes available to the
minimum flash requirements for the new system image.
• If the available memory is equal to or greater than the new system image’s minimum flash
requirements, proceed to the
“Copying the System Image into Flash Memory” section on page 10.
• If the available memory is less than the new system image’s minimum flash requirements, proceed
to
Step 5.
Step 5 From the displayed output of the dir flash: command, compare the number of bytes total to the size of
the system image to which you want to upgrade.
• If the total memory is less than the new system image’s minimum flash requirements, you must
upgrade your compact flash memory card. See the hardware installation guide for your router.
• If the total memory is equal to or greater than the new system image’s minimum flash requirements,
proceed to
Step 6.
Step 6 dir /all flash:
Use this command to display a list of all files and directories in flash memory:
Router# dir /all flash:
