Using VMware vCenter Converter

As an alternative to previous methods, you can use VMware vCenter Converter Standalone to extend virtual disks and adjust disk partition size on VMware VMs running on ESXi or VMware Workstation. Prepare enough free space because a new VM is created by VMware Converter, and data on the source VM is copied to the destination VM.

In this example, I expand a virtual disk of a Windows VM from 18 GB to 22 GB with automatic resize of a system partition (disk C:). As a result, I have V2V (virtual to virtual) conversion in this example.

Open VMware vCenter Converter Standalone, and click Convert machine.

Source System. Select the type of the source VM. You can select a VMware infrastructure VM (a VM residing on an ESXi host in vSphere) or a VMware Workstation VM. A source VM can be powered on or powered off. I select a powered-off Windows VM residing on an ESXi host. If you select a VM on an ESXi host, enter the credentials of the ESXi host or vCenter Server that manages the ESXi host with the VM. Hit Next at each step of the wizard to continue.

Source Machine. Select the source machine whose virtual disks you want to expand by using VM conversion.

Destination System. Select the destination VM type – a VMware Infrastructure virtual machine or VMware Workstation virtual machine. Select the VMware product for compatibility. Enter the virtual machine name and location.

Options. Click Edit data to copy to expand disk options. In the drop-down menu, select volumes to copy and hit Advanced. In the following table, select the needed virtual disk, partition, and set the destination size. Select the Create optimized partition layout checkbox to extend the partition to fit the size of the expanded virtual disk.

Finish the wizard, and wait until a copy of the VM is created by VMware Converter. Then, if everything is correct, you can delete the source VM.

Method 3. How to Extend C Drive Space with DiskPart CMD Commands

“Virtual Disk Service error: There is not enough usable space for this operation”.

In this case, you have two options: 1. Revert to Method 1 and extend C drive space using EaseUS Partition Master; 2. Delete the adjacent drive behind C drive to get an unallocated space.

If you prefer the 2nd option, remember to back up all useful data to another location first. Now, follow the steps below to extend C drive for free:

2 Delete Junk Files by Storage Sense

If you have a Windows 10 #1903 (released on May 10, 2019) or a newer version, then you can also take the assistance of Storage Sense. It is an inbuilt Windows Utility tool that can help you free up space on C drive automatically.

While working on your Windows system for a while, chances are that you might end up accumulating a lot of temporary data.

The best way to clear the C drive is by cleaning its temporary data at regular intervals by using the Disk Cleanup Utility.

1. There are multiple ways to access the Disk Cleanup app. One of the easiest ways is to look for it from the start menu.

4  Empty Recycle Bin

If you are a regular Windows user, then you must be familiar with the Recycle Bin. Ideally, when we delete something from the system, it is moved to the Recycle Bin, where it is stored temporarily. Therefore, you can check the Recycle Bin storage and clear it to free up space on C drive. While doing so, just make sure that you don’t get rid of any important file.

1. There are different ways to empty Recycle Bin. For instance, you can just select its icon from the desktop, right-click, and choose the “Empty Recycle Bin” option.

In this way, you can keep your files to another location separately without losing them from your system.

1. Simply connect the second hard disk or an external hard drive to your system and wait for it to be detected.

2. Now, go to My Computer > C Drive and browse the data you wish to get rid of. Cut it from here and paste it on the hard drive.

3. If you want, you can also right-click the file/folder you wish to move, go to the “Send to” option, and select the connected hard disk as a source. This will directly send this file/folder to your hard drive.

6 Disable Hibernation in Windows 10/7

A lot of Windows users put their system on hibernation to save power and time. Though, it can backfire – since the feature creates a dedicated system file (hiberfil.sys). During the hibernation, the file would store all the vital details of the system so that you can start from where you left off before. Ideally, it is not recommended to turn off hibernation, if you are used to it. Nevertheless, if you wish to learn how to clean C drive, then you can give this option a try.

1. To turn off the hibernation feature, you need to launch the Command Prompt first. Go to the Start menu to do it. Just make sure that you launch Command Prompt as an administrator.

2. After when the Command Prompt is launched, simply type and enter the “powercfg –h OFF” command.

3. Alternatively, you can also type the “powercfg /hibernate off” command and press enter. This will automatically disable the hibernation mode on your system.

In the latest Windows systems (like 7, 8, or 10), there is an option to restore the system files after an unwanted crash. While most of the experts would recommend keeping the feature enabled, it can end up taking a lot of space on your drive. Therefore, you can consider disabling this only if the C drive is running short on free space. To know how to increase C drive space by disable the System Restore option, follow these steps:
