Post Win 7 install, I find my 40 GB partition is virtually full. This is a clean, naked install. Check each of the folders on the C drive and nothing approaches the size the drive is reporting. I've run Disk Cleanup and did a CHKDSK at startup. What is taking up that much space and how can that be recovered?
Mac mini, OS X El Capitan (10.11.3), 16 GB RAM/240 GB SSD
Two very large files are automatically created by Windows, and the size is based on installed memory (RAM). Here is an example. See the highlighted entries which take up 28GB disk space.

Thanks. I booted back into El Cap and looking at the drive revealed exactly that. I'm guessing deleting those files would cause havoc so leaving them alone. I'm now in the process of using Camptune from Paragon and bumping up the partition size. I bought the 3-in-1 Mac bundle w/ the NTFS driver for Mac and the HFS driver for Windows. I just wish there was some more documentation on this as a minimum size should be closer to 50-60 GB given the size of these files.
Oh, while I'm on a roll, it would certainly be nice if Apple Stores had a Boot Camp class to assist users if they wanted to venture on the Other Side. Apple basically says Windows installs are a Microsoft problem and MS says it's an Apple problem when Macs don't boot Windows correctly. Maybe Apple should just buy Parallels & build in a Windows compatibility layer like the whispered Red Box from when NextStep was getting ported and relabeled as OS X.
I suggest you do not use any third-party software for resizing. It is a new installation, just remove it, and install with a larger size. I would recommend 80-100GB to start with.
Boot Camp Partition Nearly Full
