Part 1. How to Reallocate Disk Space
Part 2. How to Reallocate C Drive Space

"I have 2TB of storage divided into two drives, C and D. I continue to get messages that I'm running out of disk space on drive C (currently allocated at 118 GB), so I tried to shrink drive D (with 1.4 TB of available space) to expand drive C. The process of shrinking drive D worked. But when I went to reallocate the freed space to expand drive C, the "expand" command was shadowed out, and I was unable to expand drive C. Am I missing something in the mechanics of reallocating space? Has anyone experienced a similar problem and, if so, can you share how this can be facilitated?"
