There are few different ways you can move installed games from one hard drive to another without having to re-download them. The method I used involves manually moving the game folder to a new location and then creating NTFS Directory Junction to trick U-Play into thinking the game is still in its old location. I used this to move U-Play game Assassin’s Creed Syndicate, but the same method should work with Steam, Origin and other games.

• Locate the original game install directory and move everything to a new location.
  In my case I moved directory “D:\InstalledGames\Uplay\Assassin’s Creed Syndicate” to “C:\InstalledGames\Uplay\Assassin’s Creed Syndicate“. Basically I was moving the game to an SSD drive to benefit from faster load time while I was actively playing the game.
• Launch elevated command prompt and run following command:
  mklink /J “D:\InstalledGames\Uplay\Assassin’s Creed Syndicate” “C:\InstalledGames\Uplay\Assassin’s Creed Syndicate”
  J – instructs mklink to create a directory juction.
  “D:\InstalledGames\Uplay\Assassin’s Creed Syndicate” – Junction location (path where the game was installed originally).
  “C:\InstalledGames\Uplay\Assassin’s Creed Syndicate” – Target location (path where you moved the game).
• Check “D:\InstalledGames\Uplay” to make sure the directory junction was created. It’s icon looks like a normal shortcut, but if you double click on it you won’t be simply redirected to the target folder, instead you can browse inside the target as if it still was in its original location.

That should be it. If you did everything correctly, U-Play will not notice any changes and the game will launch just fine from its new location.
