I had nearly 100 GB of free space on my hard drive. After editing 3 different events from an external hard drive totaling 40 GB, it appears that they have been moved to my computers hard drive as I now only have 53 GB of space available. I have my Adobe Lightroom Import settings at Add so I assumed that it would be doing the work from external hard drives. Can anyone explain why my computers hard drive seems to be losing space every time I use Lightroom?
For some detail on 'Where to Store and Find your photos', read-
So first step- discover where your photos really are.
Second- if your Catalog is on the computers Hard-drive then it will have the Previews folders in the same location. The Previews can get large if you have many files and more so if you create 1:1 previews and Smart Previews.
And have you searched the drive to find what has occupied that 47 GB of space?
