This is fairly simple - it's pretty much a copy and paste job.
- Find the location of where your current launcher is located. Mine is at
C:\Program Files (x86)\Minecraft\
- Copy this
Minecraft folder, and paste it into your new SSD wherever you'd like
- Find where the actual game files are (the
.minecraft file). Mine are located at
C:\Users\Gamem\AppData\Roaming. You may need to enable "Hidden Items" within File Explorer so that you can see the
AppData file. Note that the
Gamem part of the path will be whatever your user name is
- Copy the
.minecraft folder and paste it into your SSD wherever you'd like.
- Launch the launcher from your SSD, and go to "Launch Options."
- Click on the release version, and press the switch to the left of the "Game Directory" to enable the text box
- Paste in the file path of where your
.minecraft file is on your SSD
- Save, and the game should load from here now when you launch it
Note that you shouldn't have to move the launcher to your SSD, just the game files. If you don't want to the move the launcher, skip to step 3. Also remember that if you are copying and pasting (and not cutting and pasting), you will have duplicate files in different locations. This shouldn't matter, but it will take up more space on your disks. So, either delete them after you move them, or just leave them.
