I want to trick windows into thinking my ssd drive has more free space than it does.

An obvious question is why would I want to do that? Well, I do some ark mod developing using the dev kit, which is a UE4 based product. When it updates we can download an update, a patch which might be a few gb in size. But the Epic launch tool that we use to download and apply the patch is brain dead. It checks the drive for the amount of free space required to install the entire application, in this case about 120gb and will refuse to proceed without that much space, despite the patch really only needing about 5gb.

So I have ~100gb free, and cant install 5gb patch and Epic don't think it needs to fix this feature of their brain dead installer.

So, can I trick windows into thinking the disk has more free space than it does?

  • Your saying a 5GB patch won't install because you have 100GB free instead of 120GB. You can't fake disk space. – Ramhound Mar 14 '17 at 21:32

    The best you could do is to create a junction or link with the mklink command to another drive which has more space. – cybernard Mar 15 '17 at 23:28
  • I was already using a link from my HDD C: to my SSD D: but it was only 256gb, I bu the bullet and brought a 512gb to house my 120gb application. – Rob Mar 16 '17 at 6:27
  • I already used mklink /j to redirect application defaults location to other drive, but installer still checks C: free space and does not proceed. I would like to bypass such check... as I have prepared joints link so that it succeeds – Yves Martin Nov 29 '17 at 10:50
