When downloading Rainbow Six: Siege on Steam, it gives me the error "Not enough disk space..."
I tried reinstalling again, but when it reaches 90%, it shows me that error message again, even though I have 120GB free space on my disk drive.
PS : when right-clicking on the game library, and then going to Properties/Browse local files, it redirects me to the the Rainbow Six: Siege game directory, which is empty. If I search the location of the downloaded files during the download, I find that all the downloaded files go to Program Files (86x)/Steam/SteamApps/Downloading
I have already tried:
- Verifying Integrity of game files;
- clearing the download cache;
- repairing the directory folder;
- and reinstalling steam.
What could be the cause for this?

downloadingfolder, before moving everything to the game folder. Are you using Windows 10? Is it an HDD or an SSD you're downloading on? For now, I recommend running Windows' Disk Clean-up, which can be found by searching in the Start menu. My guess is that lots of files are flagged for removal, but not actually removed. – Joachim Feb 12 '19 at 16:38
