I always understood that using IR will affect the size of any images you also create. This seems logical to me given that the snapshots are saved on your OS drive and will have to be imaged too. Since I used primarily archives on a separate harddrive and only left a stripped down snapshot on the OS the effect of this size increase was limited to about 15 gb. So when I removed IR yesterday I expected the size of my OS to drop accordingly. While I did not check the relevant data before the removal yesterday, I am surprised to see the current size still about the same size as I thought it was before. Is it possible that despite the removal of IR, the snapshot is still in some hidden file and did not get removed at the same time? Where should I look in this case? On the other hand comparing the Macrium image I took before and after do vary by about 5 gb. That seems more than just "normal" shrinkage due to a program removed but less than the original size of the snapshot.
