i have three partitions on my computer which are

  • C - 80GB
  • D - 166GB
  • F - 204GB

I need to increase the C: as to transfer the F partition capacity to C:. Can that be possible and how without rebooting.

  • Are these three partitions all on a single hard drive? What operating system is your computer running? (Be as specific as possible.) Feb 6, 2013 at 8:01

It's not possible without rebooting, as C: likely contains your operating system (Windows).

Assuming F is empty (or mainly empty), i.e. you can't shrink partitions if they contain data, I'm assuming that 3 partitions are in the same order as the letters, i.e. C: is the first partition, and F: is the last.

So you need to boot (via a CD) into a partition editor to do it, the tool you use might have a wizard to do this, but they didn't when I last did this.

The manual steps are:

  1. Shrink F: by the amount of space you want to add to C:
  2. Move F: to the end of the disk(creating a space between D: and F:)
  3. Move D: to be next to F:
  4. Expand C: to fill the gap.

Steps 1-3 can be very time consuming if the disk is heavily used and near capacity. I would recommend running a full defrag on each drive before starting.

An alternative approach: find a usb disk of 500gb or more. Move contents of D: and F: to it, then you can delete D:, F: partitions and resize C: and then recreate.

GParted is a free partition editor, or there is the commercial Arconis DiskDirector.

  • Gparted i would only remove F, move D to last position and then grow C. (from 'transfer the F partition capacity' i would assume F is no longer needed). Another funny approach could be to move a large directory from c to f and create a junction to that directory on C

    what do you mean "non of those two works", the apps certainly do work. I would do what Offler suggested, delete F, shrink and move D to the end and then expand C.
