Windows 10: 256GB C OS SSD drive nearly full. Its folders total only total 90GB ?

I have a 237GB SSD C drive which is showing it only has 16 GB of storage remaining.

I have added up the storage space of all its folders and miscellaneous files which total less than 90 GB.

It would seem that there should be 147 GB of storage left

What am I missing???

Upgrade SSD drive from 128Gb to 256Gb

IDK about the 128Gb SSD, it's considered old and outdated. I'm putting it on the Wall

and framing it.

LET's Keep focused on the newly installed 256Gb SSD Only, please.

The newly installed 256Gb SSD :

The C: SSD shows 118GB with 29.7GB free &

another 118GB unallocated.

Should not I expect or be able to have All of the SSD total amount

to be assigned to C: only?

Ty,

P.S. I can remember the good ole days of MS-DOS 3.3 when I had total Control.

It was simple days... less headaches.

 

Discrepancy between 'Used Space' on C drive and total of actual folders/files

According to 'Properties' in Windows Explorer, my C drive (one of four partitions on my primary drive) has 296GB 'Used Space' and 272GB 'Free Space', giving a total partition size of 568GB. However, if I add up the total space occupied by all the folders
and files on C drive that are listed in Windows Explorer they come to roughly 44GB. (The largest folder is Windows (19.5GB), followed by Users (9GB) and Program Files (5.8GB). The rest of the folders are smaller than this.). Nearly all my applications, data,
photos, videos, backups etc are on the other three partitions on the primary hard drive or on a secondary internal hard drive.

Can anyone suggest what accounts for the HUGE discrepancy between the reported 'Used Space' and the total of the actual folders/files? I first noticed this when backing up my C drive using Acronis TrueImage, which yields a back up file of 218GB - presumably
the 296GB with some compression. A few months back I recall that the Acronis backup files were sized at around 60-70GB, so there's something funny going on! If there is some giant folder or file that is lurking on my C drive, what could it be and why isn't
it showing up in Windows Explorer?

 

Windows 10 Displaying Incorrect Total Size of Drive. [Fixed: Was problem on Mac OS displaying incorrect total size]

Hi, I currently use a MacBook Pro and am Dualbooting Windows 10.

The problem I noticed with Windows 10 is that it doesn't seem it display the correct size or free space of the drive.

My SSD is 256GB, I understand that it shouldn't display the full 256GB. On Mac OS it recognises the drive as having 250GB.

But on Windows it shows that the drive is only 233GB.

When I was partitioning space for boot camp, I partitioned 100GB for Windows, and 150GB for OS X. In OS X it says the Windows Partition has a total space of 98GB and 148GB for the Mac OS partition.

However on Windows 10, the Windows Partition only shows a total size of 93GB, and only 140GB for my OS X Partition.

This is a huge discrepancy between the two, and I was wondering how I can get Windows to recognise the FULL SIZE of the drive, and the partitions.

Thanks.

Update: It seems that Mac shows storage differently... I have a total space of 251,000,193,024 bytes, which IS 233GB but Mac shows it as 251GB...
