https://stackoverflow.com/a/64219885. But 4.5GB is rather small compared with Windows itself and some popular application on Windows (such as Ms Office), so i wouldn't bother move it.
It's an undersized Windows partition I am afraid to make bigger (or even join) because MS decided to make a recovery partition between my two useful ones from the (rather small) SSD.
And.. yeah, LibreOffice is moved long ago, some other things too; I've even moved pagefile.sys.. so I was a bit desperate.
I've installed that app with chocolatey, ran the command line, got some warnings, but went through. Now that Debian is successfully moved to HDD, I don't even mind if it's slower.
All in all, that link is pretty much a life saver;
Thank you.//OP, sorry for the off-topic//
