I play "uma musume" and it store about 300mb in my E drive(my set drive to store steam games) and about 6gb in appdata/locallow in C drive. My C drive free space is low so i uninstall the games, before uninstall i have around 11 gb free, and after uninstall i have 16. But after i restart my pc, my C drive only have 9gb free left, so i try to figure out what happen and i found this:

1. If i reinstall the game and has it update the 6gb to the locallow file then restart, i will have 11gb free again.

2. I use windirstat to check, then i found out that whenever i uninstall the game then restart, a file called "pagefile.sys" will appear and take up about 8gb of my free space, when i reinstall the game it'll disappear.

I search on google about this file and find that it's not safe to delete this file. So i try to set it to be clear after shutdown but it's doesn't work.

So do anybody have an idea why it only appear after the uninstall? And how can i uninstall the game and have my free space back?
