[Suggestion] un-Y2K Screenshots
Ugh, I have 1000 screen shots. 
Don’t suppose we can un-Y2K screenshots? 
When I notice I’m approaching the limit, I just rename the folder and move it to my screenshot archive. (Renaming is enough. I keep my archive on another, more spacious hard drive.)
I was using them all as my background in a slide show. I’m not sure if I can have one ‘set’ of backgrounds in two or more locations?
I wonder, if I mass rename them all to something else, and keep them in the folder, if the new shots would come in? Is it just looking for ‘gwnnn’ with the biggest number and trying to add one to that and bailing if it’s 999? Could I call them all ‘y2knnn’ and then it would start over?
Guess I’ll try that.
For what it’s worth, that worked as hoped. Not being terribly picky about what they are called, I selected all the existing ones in explorer and renamed them ‘a-gw2’, which produced ‘a-gw2 (1)’, etc. Took some new screenshots and it started over with ‘gw2001’.
This way I can keep my background set to use that folder, and it just keeps adding new ones into the mix. 
I usually rename and move screenshots that I want to keep. There are free tools that will do multi-rename.(definitely for Windows, probably for Linux, and maybe for Mac as well) (in my experience)GW1 & 2 will ignore screenshots renamed so that they don’t fit the name format that GW uses.
