You'll then see a folder with a little link icon, and it should already be named 'osu', if you doubleclick on it you'll see the osulazer filesnow when your osulazer tries to install songs, it'll actually install in that source folder where you want them to, but it'll think it's doing it in the appdata/local folder which is where it always tries to put it. Then, back to appdata/roaming and right click, Drop As > Junction If you see some Osu Wallpaper HD Download free you’d like to use, just click on the image to download to your desktop or mobile devices.

Then right click that folder and hit 'Pick Link Source' See the best Osu Wallpaper HD Download free collection.

Once that's installed, go to appdata/roaming and cut the osu folder and paste it wherever you want your songs and stuff to actually be saved. First, I'd suggest installing the program here which will make this process a bit easier (don't need to use command prompt, can just right click in file explorer) Just making this post incase anyone else runs into this problem or is a bit confused and finds this post.
