Delete a lot of files from the Compact Flash card of a Cisco ASA

Today just out of the box a Cisco ASA 5505 contained a lot of FSCKxxxx.REC files. I saw this when using the show flash command.

ciscoasa# sh flash

Well you see in this example 16 FSCK Files. which could be deleted. To do this you have to issue the following command.
Del disk0/*.REC ( the 0 is a number Zero )

ciscoasa# del disk0:/*.REC

Delete filename [*.REC]? 

Delete disk0:/FSCK0000.REC? [confirm]

Delete disk0:/FSCK0001.REC? [confirm]

Delete disk0:/FSCK0002.REC? [confirm]

This way helps you to delete all these REC files in one time. When you Show Flash you see that all teh REC files are gone.

ciscoasa# sh flash
