How to delete multiple files from a Cisco router flash memory

Question

I have filled up my router's flash with voice files and folders and wanted to remove them. I there a script that can delete all files in flash except for the IOS image?

Answer 1

delete flash:<file> is the command here. Depending of how are named your files, you can either to use a joker :

Router#delete flash:*.bak
Delete filename [*.bak]? 
Delete flash:/test.bak? [confirm]y
Delete flash:/rhgreg.bak? [confirm]y

If this doesn't work, you could try to write a TCL script, but I won't be able to help here.

Last option, copy the IOS image to a ftp/tftp server and delete /recursive flash:
