BENEFIT OF PORTABLE EDITION
Just extract the setup to any location to any drive/USB etc ,so that you can run it from those desired place.
It’s per-activated , since portable it doesn’t have any background services.
No need to install again & again like usual installation procedure even if you format your system.
CONS: Since it’s portable PSD files can’t be opened while it’s closed , means to open a PSD file you’ll need to start Photoshop first, then you can open PSD.
