Solved What's taking up my hard drive?

[mercurius]

Just happened to check my hard drive this morning and was shocked to discover that out of the total disk size of 1TB there's only about 80GB free. I have done a folder by folder check and can only account for 340GB.

I did create a system image some time ago, but thought that was saved to my back up drive.

Any suggestions as to how to identify what else is on there?

Hello Mercurius, and welcome to Seven Forums.

You might see if using the tutorial below may be able to help ID what's using your hard drive space, and then be able to free it up if you like.

Hope this helps for now,

Hi Shawn,

Thanks for this help,

I've just run WINDIRSTAT and it is showing that there's only 389GB on the drive. But there's nothing to show what's taking up the other c500GB.

Do you use Avast anti virus program?

If you could completed your system specs it would also be helpful.
This tutorial by Brink will be helpful to get you started.

Take a look at Brinks specs and mine and it will give you a idea of helpful information that can be put in My System Specs.

Hi Shaun,

Just clicked on 'Show Unknown' in Options and it's now showing 425GB as 'Unknown'.

Any idea how to find out what this is?

 

[mercurius]

Yes, I do. Thanks for the tutorial. I have updated as much of my profile info as I can using the tool you suggested.

See if WizTree can show you where the unknown is used.
They have a Portable Zip available, no install needed.
Antibody Software - WizTree finds the files and folders using the most disk space on your hard drive

Check your max space used for System Restore.
Avast has a known bug to set this to 50%.

Hi DavidE,
Ran WizTree and it has identified 75 files in System Volume Information with a total size of 454GB. From the format they look like some form of back up file. I wonder why they are here and not on my back up drive.

 

[Brink]

It sounds like it's restore points using the space.

 

[Layback Bear]

Their are problems all over this forum and the web about Avast creating unwanted Restore Points.

I believe most of the members with this problem went to the Avast forum and found a cure.
Basically what is happening is Avast is moving your amount of disk space for restore points to 50% and just keep adding restore points and filling up the disk.
I will find a member that had this problem and ask her to help.

H Layback Bear,

Ah, so that's the problem! Thank you very much for the offer of help. That's very kind of you.

 

[Lady Fitzgerald]

I ran into the same problem a short while back and several of the guys here, most notably DavidE, were able to walk me through how to fix it for now. Look at this thread, starting with post #6.

 

[Layback Bear]

Thank you Lady Fitzgerald for answering my call for help.

 

[mercurius]

Hi Lady Fitzgerald,

Thanks for the link. Some of the talk in the thread though is above my technical competence. I don't follow how to delete existing restore points. Any chance you could talk a non-technical user though that?

Thanks in advance for your help.

Many thanks DavidE. That worked for me! I followed Option 1 to delete them.

Will they stay deleted or will I have to keep doing this every now and again (I am carrying on with Avast Antivirus Free version).

Just another point on that, I also selected the option 'Turn off system protection', thinking that this was the way to stop restore points being created again in future. Now I'm wondering whether this was the right thing to do. Could you please advise what the implications of this are?

Secondly, do you have a tutorial on best practice for backups and what the difference is between taking back ups and making system images? I've just wiped my back up drive and need to set it up again, but want to know what the best thing to do is.

Finally I would like to say to everyone who has responded to my query, thank you very much for all your kindness and help!

 

[Brink]

Mercurius,

Turning off system protection would just mean that you will no longer have any restore points available to be able to do a system restore if needed in the future.

If you would like to keep having restore points, then you could turn system protection back on for the C: drive, and limit the space used for restore points to what you want instead.

If you keep good updated system images, then you should be fine though.

A system image is an image backup of everything (all system drives). A Windows Backup is only a backup of folders you selected to be included in the backup.

If you like, Macrium Reflect Free is a good 3rd party option for system images. It's a bit more flexible and reliable.

If you have turned off system protection, you can't do a System Restore. You'll have to watch your hard drive free space to see if Avast continues to chew it up.

Some people have trouble with System Restore and are glad to have it turned off. I've had no problems with it. System Restore in my experience runs as expected perhaps 97% of the time. It can be a quick way of returning your system to the way it was a day or a week or a month ago. That can be useful when you've installed something you wish you hadn't or when you have unexplained problems that you can't quickly resolve. For the 3% of the time that it fails to solve your problem, you have to resort to some Plan B.

Plan B can be manual trouble-shooting or restoration of a system image.

System images are a proper "backup" of an entire partition, unlike System Restore.

I use both. If System Restore doesn't bail me out, I restore an image. I've only had to restore images twice in 5 years, but I was glad to have that option when the time came.

Best practices would dictate the use of imaging--with something like Macrium or Aomei. You'd make a new image periodically, perhaps weekly or monthly.

You have to store the images and they can take up considerable space, depending on exactly how much space is used on your imaged partitions--maybe 15 to 50 GB each.

But no reason you can't use System Restore as a first line of defense. Just have the image fallback as a last resort.

Look for a Macrium tutorial on this site by member WHS.

 

[Lady Fitzgerald]

Macrium Reflect Free (here is a good tutorial on how to use Macrium Reflect).

Imaging is the best way to backup system files (OS and programs) but is too slow, space consuming, clunky, and inefficient for backing up data (other than a tiny amount). For backing up data, I prefer a folder/file syncing program, such as FreeFileSync. To use a split system like that, one should have their system files on their own drive or partition and the data segregated to its own drives or partition.

You're welcome and glad to hear you have the problem solved for now.

It's a bug that should be fixed in June/July, so you should keep an eye on disk space to see if the problem happens again.

Now that we know you have Avast FREE, you shouldn't have the option that would cause this problem.
It's caused by Avast NG, aka Avast Secure Virtual Machines, aka Avast Sandbox.
They have changed the name for this "feature" making things more confusing and difficult.

Go to Control Panel > Programs and Features.
Select the Avast program.
Click on Change.

If you see Secure Virtual Machines (aka Sandbox or NG) checked, uncheck it and continue to uninstall it.
Reboot.

Here is a screen print example of what you should see if you want to change Avast options:
I only have the basic protection installed, no optional components.
