Hi,
You want to free some space on your flash, is that so?
870 routers can go up to 52 MB of flash and 256 of SD RAM. Can you tell us how much you got with show ver output.
If you are 95% of flash I don't think this will impact performance as the IOS is copied into RAM at startup but if you want to implement
features needing files installed in flash you may be missing some space.The more memory you got the better and anyway some features need a lot of RAM to work.
I f you want to free space on flash then you can put IOS on tftp or ftp server and boot from there.
Regards.
