If you don't want to do it the way Iconography said, you can do it like this: BACK UP YOUR GTA V FOLDER! Just in case.Exit Steam and copy the GTA V directory and paste it where you want the install to be. For me that would be my SSD so I'd move my "Grand Theft Auto V" folder from C: > Program Files (x86) > Steam > SteamApps > Common to my SSD (which is F Drive) F: > Steam > SteamApps > Common. If it's just making a mess on your SSD you should create the Steam, SteamApps, and Common folders manually.Go back to where GTA V is installed and to the SteamApps folder, and find and copy appmanifest_271590.acf. Now copy that over to your new SteamApps folder you just created.Open up Steam and hit "Delete Local Content" on GTA V. Wait for it to uninstall and then click install but select your new Steam folder you created on your SSD, Steam will detect the GTA V files are already there and skip the download. Enjoy GTA V!
