I use Partition Master, they do a Home (free) and a Professional version.
Now I haven't needed to use it for over a year (or maybe two) and I seem to recall that may have been due to the software not being updated for Win7/8/10.
But when I had used it, I was impressed.
It could split and merge, but from memory, the merging had to be with adjacent partitions of course.
Since Win7, the inbuilt DISKPART command can do some amazing things now.
Plus I now try to get the partitions right from the get-go so I don't need those 3rd party re-organisers.
Go Luck with the hunt. I'm sure you'll let us know your findings as I'd be curious.
Any suggestions what is a good minimum partition size for the win 7 and win 8 OSs?
if you deactivate the hiberfil.sys and set the pagefile.sys on another partition or hd + install games also to another partition... i have 64 gb used hdspace on w8.1 64 included hiberfil and pagefile (depends on theamount ofinstalledmemory!). --> perhaps 80 gb?
you couldalso turn off the systemrestore,if youdont need them.
Its pretty great and can work with file systems that windows will sometimes have issues with. Just have to be careful because it doesn't have the same safe guards the windows one has. You can literally do anything to the drive with it and you wont get any warnings. But it does work great.
My Win10 only takes up <40gig (OS and programs files).
All other storage is done on the HDD (pagefile, user files) and all system drive accessing/storing services are disabled (prefetch, hibernation, restore points).
Don't forget to factor in Over Provisioning of around 10% if you have/get an SSD.
When you say "accommodate win 7, 8.1 & 10" I assume you don't mean all at the same time.
(memories of your dual boot XP experience flood back)
90gig OK for system? - Absolutely. In fact, way too much.
Windows folder is 15gig, Program Files (x86 and x64bits) total 12gig.
I have those on a SSD and everything else on a separate HDD.
And being a SSD is the only reason I have all those high I/O services disabled, otherwise they are fine to leave on.
But you are right, the answer will vary per user. I've been checking Windows and Program Files folder sizes since XP and they have never exceeded 20gig each.
So really, only a 60gig partition would suffice. And that still allows room for the paging, hibernation and restore point files.
As an exercise, I think all your updating, backing up etc will be a great experience.
Windows built in disk mgmt shows the HDD to be 920 gb with about 867 gb free and 52.7 gb used..
The shrink partition option showed only 457,101 mb of "shrink space" available, so I did that.
Simple volume wizard worked fine.
Now there are 2 partitions, C: at about 473 gb and the new one at about 446 gb.
Shrink partition option says no more shrink space available on C:.
Still boots and works OK, but it is a far cry from the 80 or 90 gb C: drive I would like to have.
Questions.
I didn't change pagefile or hiberfile, didn't delete the restore points or the leftover updates. Would that make the difference?
If I use one of the other softwares to shrink the partition down to 80 gb, will data be lost? Remember its a GPT UEFI system, if that makes a difference.
