Step 1 Enter privileged EXEC mode:
Router> enable
Password:
<password>
Step 2 Enter the copy flash:[partition:filename]{slot0: | slot1:}[partition:filename] command. Replace
partition with the partition number and filename with the name of the file, for example:
Router# copy flash:2:TESTFILE slot0:3:TESTFILE
PCMCIA Slot0 flash directory, partition 3:
No files in PCMCIA Slot0 flash
[0 bytes used, 4194304 available, 4194304 total]
Verifying checksum for 'TESTFILE' (file # 1)... OK
