It might be time to clean up this folder of older Cisco documentation.
Why do I have this ?
Because Internet access wasn’t guaranteed in the early to mid–2000’s. More than once I was in a location where the network was down and no access to documentation. Having the PDFs on my hard drive got me out of a tough spot in rural Ireland where the only internet connection was several miles away after clearing a security checkpoints. (Hotspots on 3G phones were just a dream).
Its not worth keeping in the era of the Internet.
