Kim, An external drive can host the cache. I currently use a 1 TB Iomega eGo USB 3.0 small and portable hard drive for this purpose, but there are many others (WD My Passport, Toshiba Canvio, etc.) If your laptop takes USB 3.0 by all means get a drive for that. It is much faster the USB 2.0
Let's say the laptop denominates it drive E. In your CN2 preferences you make that drive the cache recipient. For example:
As you can see above, I created in that external drive a folder named 'CNX2' and a subfolder named 'Cache'.
What this does is leave the main disk drive in your laptop (C) free to do just the processing, and not the storage of intermediate steps and monster-size TIFF images. This also reduces the fragmentation of your main disk data, which usually and eventually cripples its speed.
You don even need to create the subfolders if the only purpose is to use it as cache. I use the drive also for critical files backup, before they go into my main PC, hence the need for specifically named folders.
In yet another external drive are my newest images and all changes and additions, later to go into one of the disk drives at my main PC, frequently, and into a full images backup disk.
I also use an external drive for cache on my main PC that, with 32GB RAM, is instantaeous for processing and post-processing images. Attachment#1 (jpg file)
