I am trying to make my C Drive bigger. I successfully shrunk my D Drive by 20GB. I created a new volume and called it E: It is empty and sitting next to D:

When I go to C: to extend it, the option is greyed out. I can shrink it, and am def the Admin, but Extending it is not an option.

Everything looks fine otherwise as per the attached image.

Do I need a third-party app?

What is a safe app to do this. Ideally I want more, but I thought I'd play safe and try this with 20GB.

I have just installed Band In a Box 2022 and it has eaten up every bit of space I had left.

I welcome any suggestions, thanks

Sorry, the C: drive is on a different physical disk to D:/E:, and which has no available space to grow into. This is why the option is greyed out.

Unfortunately, you can't grow the C: drive using space from another physical disk.

Thanks James. That sucks. It says I only have 3GB of free space.

I guess I'll have to uninstall something, but I don't have much left. Maybe Nortons.... *jokes

If the program must be installed on C:, you could use NTFS junction points. It works like a shortcut.

Or you could uninstall and reinstall the program this time onto another drive with free space.

For move to NTFS junction points, if your program was installed to the C:\bb folder, first move the folder and its contents to say D:\bb or E:\bb, then in command prompt run mklink /j C:\bb D:\bb (or E:\bb) (the format is mklink /j <link> <target>)
You may need to elevate to Command Prompt with Administrator privileges if you working with C:\
Don't forget to use double quote marks if the path contains spaces.

Junction points can be removed when no longer needed using the rmdir (or simply rd) command. e.g. rmdir C:\bb Here the shortcut C:\bb is removed. The target folder/files are preserved.

Shuffle your drives about...

For resizing partitions I use EaseUS Partition Master.

Edit: I just looked at your Disk Management screenshot - as @jamesrt said you only have 1GB of available space to extend into, so the question is moot.

Or alternatively if your personal folders (Documents, Downloads, Music, Photos, Videos) are using a significant amount of space, use Properties / Location / Move to move them to your D drive

Treesize is a good bit of sofware to find out what is hogging space

Windows 10 and a few apps would likely use only 80 to 100GB of C: drive.

What you might be best to do is uninstall band in a box, and reinstall it, but tell it to install to D:

Similar thoughts here.... but we don't know the performance of the OP's drives...

I was thinking of splitting the D: drive0 into 2 500GB partitions.... moving the data to second half and then cloning the C: drive1 onto the first half of drive0.... many ways to approach it....

Hopefully the OP has got good backups before he restructures his computer 😀

If you are using OneDrive, a significant part of your storage is user data on OneDrive and the OneDrive is pointing to C:, you can use OneDrive On-Demand to set the folders to store on the cloud and only download if needed.

Thanks folks, I'm going to have to come back to this in a couple of days.

Mauricio, I already had that selected but most of my files on Onedrive are data on my D Drive, particularly photos and videos, so I assume they don't have a footprint on C:

As to the suggestion of moving Band in a Box to D, or another partition, I thought programs had to run off C Drive. Has this changed?

Band in a Box must be huge. Your best bet is to re-install it to your existing D: drive or run it from and external hard drive.

If you were to re-arrange partitions and move Windows, your BIOS/EUFI can can be made to boot off any partition.

Once in Windows the Computer Management/Disk Storage that you have used can re-assign drive letters and C: drive for the new Windows partition.

Can be tricky to re-arrange....

If it gives you an option to change directories during install. You can put the application anywhere you want.
