The fedora partition is the 2nd partition and sizes are as follows:

$ fdisk -l /dev/sda
Disk /dev/sda: 931.5 GiB, 1000204886016 bytes, 1953525168 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 4096 bytes
I/O size (minimum/optimal): 4096 bytes / 4096 bytes
Disklabel type: dos
Disk identifier: 0x0004ccd9

Device     Boot      Start        End    Sectors   Size Id Type
/dev/sda1  *          2048   84033535   84031488  40.1G  7 HPFS/NTFS/exFAT
/dev/sda3         84035584 1919970735 1835935152 875.5G 83 Linux

I want to move sda3 start position some 32GB to the right, thus 
shrinking it by 32GB.
sda3 is the fedora boot partition and formatted and mounted as ext4.

P.S: Notice that sda2 is missing - because it was a tiny remnant 
partition of windows
restoration utils (about 100 meg), which had proved to be useless to me, 
since I use backup
and restore which completely obviated those tools. So, I expanded 
windows partition into what was
sda2. Of course, I had first deleted sda2 in order to use windows 
storage gui to expand
C: drive into the space that was sda2.
But still, windoze needs a little more room, as it is running out of 
swap area.
