Windows 10: C Drive storage space doesn't make sense?

My C Drive has 180 GB of storage; out of which 104 GB is being used by installed apps and 13GB by system but calculating manually only 16 GB is actually being used by the installed apps. I tried cleaning up but it's still the same I don't understand what is happening.

extend c drive storage space

Hi, I'm , an Independent Advisor.

Disk Management is a Windows built-in tool that supports to increase partition size with its "Extend Volume" feature. However, the program has some limitations in increasing disk space:

- Extend Volume only works on NTFS and RAW partition. FAT32 and other file systems are not supported.

- The Extend Volume will grey out if there is no adjacent unallocated space behind the target partition.

So, the ways to increasing C drive with or without adjacent unallocated space are different. Open the Disk Management, and follow the right tutorials listed below to extend the local disk C drive on your own now:

#1. Increase C Drive Space with Adjacent Unallocated Space

Step 1. Right-click This PC/My Computer, click "Manage", select "Disk Management" under Storage.

Step 2. Locate and right-click on the local disk C drive, and choose "Extend Volume".

Step 3. Set and add more space to your system C drive and click "Next" to continue.

Step 4. Click "Finish" to complete the process.

Note that if that unallocated space on your system disk is not behind the C drive, you can't extend C drive in Disk Management.

Hope this helps. Let me know if I can help you further!

 

Storage Sense and Compressing drive C?

Thanks for the many useful links. Having had a 'small storage device' for a few years I have checked / used many things to reduce demands on the C drive, including removing Windows.old (I thought it was uninstalled automatically after 10 days anyway?); and Hibernation has never been activated (as is common with Tablet PCs). I use Disk Cleaner almost every day, now most often via Cleanmgr+ which is meant to replace it. Incidentally, the most effective cleaning app among several I use such as BleachBit and CleanSpace7 in addition to CCleaner (enhanced), is part of SystemUtilities ---not so well known I think.

Yesterday I decided to try the Compress option in Storage Sense, as it can be reversed if necessary. The 'bad news' is that it only saved about 2 GB, not the 10 GB suggested in Storage Sense which is still showing 10 GB to be available. The 'good news is that I have not (yet) found any negative consequences of compression, if it has slowed the system down it is not noticeable to me ---- I would not know drive C is compressed were it not for the changes it makes to folder icons. Which means that while 2 GB gain is not what I expected it is still worthwhile.

Also, Storage Sense still reports 8 GB to be available in Downloaded files with no sign that it is cleaning them when set to do so. So I still have more to find out about the failure of Storage Sense to do what it is supposed to do. It looks like I may have some time before the attempt to install the May update.
