Yeah, I'm going to underscore the last part of the MytonLopez posting:
Setting the MIN and MAX amounts to the same value locks in the physical location of the swap file AND it keeps the walls in place as opposed to this beast that swells and shrinks across non-contiguously occupied disk space.
Also, an old trick that has never failed me is to make sure the MIN/MAX value is evenly divisible by eight. That ensures the allocated space isn't sharing disc sector(s) with anything else.
When changing the values, you should go in, set both values to '0' (i.e., no swap file allocation) and then re-boot. Yes, things will move INCREDIBLY SLOWLY but only for a bit. After you're back inside Windows, set those values correctly then re-boot again. This puts your swap file in a physical location that's not prejudiced by the pre-existing swapfile.
If you have multiple drives, (actual drives, not several partitions on the same physical drive) SERIOUSLY CONSIDER spanning the swap file across the physical drives. The boot drive is always going to use/need between 12-20 megs of swapfile space --and Windows will take it, whether or not it's specified. The system drive (if different) will also take whatever it needs to cache data from minimized apps, etc. But a good rule of thumb is to split the swapfile size into fifths and give 3/5 to the boot drive and the other 2/5 to a secondary drive.
