I have a plug-in for creating my blog posts currently operating with my PS on a laptop. I want to move over to CC but I don't know if the plug in will work. Will it and how do you maintain plug-ins in something that isn't physically there on your computer. I have the same question about LR. I use VSCO films with it currently, can I use them in CC?
What do you mean " isn't physically there on your computer."? That doesn't make any sense, and doesn't seem to be related to the rest of your question about plugins.
If your plugins are compatible (some will need updates) then they should work fine in Photoshop CC.
