All you need to certify yourself

While upgrading my IOS, I was getting the error message that there is not enough space available for the new IOS. I was issuing the following command:
Certhacker#copy tftp flash: Address or name of remote host [192.168.1.1]? Source filename [c2600-i-mz.121.T.bin]? c2600-i-mz.121-1.T.bin Destination filename [c2600-i-mz.121-1.T.bin]? Loading c2600-i-mz.121-1.T.bin from 192.168.1.1 (via Serial0/0): ! %Error copying tftp://192.168.1.1/c2600-i-mz.121-1.T.bin (Not enough space on device) Certhacker#
The solution to this problem is to delete the existing files residing in the flash. To see the items in flash, issue the following command:
Certhacker#dir flash:
If you want to backup the files currently residing on flash, issue the following command:
Certhacker#copy flash tftp
This command will ask for the file name which you want to copy to tftp server.
When you’re done with the backup, issue the following command to delete all the files in flash:
Certhacker#erase flash:
This will delete all the files in flash and you’ll be able to install the new IOS without the error message which you were previously getting.
