My Laptop's HDD drive died and Curry's Tech staff doesn't want to even diagnose my PC.
I managed to copy my school works and Steam screenshots, but not the saved files 0A0!!!
Some games do have Steam Cloud function (eg. We Happy Few), but Shadow Corridor doesn't.
So, ALL my unlocked items and stages are gone 0_0ii.

I have asked Thankyou/39 san(a loyal supporter of this game since early days on Freem) on what to do during one of his Live stream (see link below). It took him awhile to locate the right version on his PC, but here it is:
C:\Users\name\AppData\Local\Kageroh\Saved
He told us to copy the Saved File to an external Portable drive(or any drive that has sufficient empty space). P.S. The ''name'' folder inside the address location should be your PC's nickname.

But, it depends on luck. No one can tell how long your PC will last and when is it entering its final days (Mines is Lenovo YOGA 2015-ish, with HDD and SSD).

My husband took out the burnt HDD off my PC, and inserted a new SSD. He says that, it lasts longer than HDD, and doesn't generate loud noises.
