How to delete big files in Windows 11/10/8/7?

After having a basic understanding of reasons for big files deletion, what you concern most must be how to delete unwanted files in windows 11. Basically, there are three options for you to clear large files in Windows 11 and other Windows systems. Let's see them one by one.

Way 1. Via File Explorer

The first one is using Windows File Explorer, which is the traditional way to manage your files on the hard drives. The detailed steps are as follows:

Step 1. Press "Window + E" keys to open File Explorer.

Step 2. Click "This PC" to open the target hard drive and find the large files you want to delete, right-click it and select "Delete" from the drop-down menu.


Please make sure you have closed the files you plan to delete, otherwise, the system won't allow you to delete out of data safety consideration.
The biggest problem is that you need know where the to-be-deleted large files exactly are, or you will waste a lot of time finding them out.

Way 2. Via Command Prompt

The second method is to use Command Prompt, which is a more advanced Windows built-in tool to manage your disks as well as files on it. Let's see how to delete big files on Windows 10 or 11 with Command Prompt.

Step 1. Type "cmd" in the Windows Search box and right-click on it to choose "Run As Administrator".

Step 2. Open your file explorer and go to the target folder or file and copy and paste the folder path from the top bar. Eg. c:\sample\mydoc.

Step 3. In cmd box type "cd path" and press "Enter". Eg. cd c:\sample.

Note: Please note the space between cd and the path. If you miss it, the command line won't work.

Step 4. Now, your directory will be changed to your folder. You can put the following command:

del filename.extension.

Eg. del test123.docx.

Then the target large file will be deleted.

The same as using File Explorer, using Command Prompt also requires you to know the specific location of the target large files. Moreover, if you delete large files on your Windows 11 via CMD, you must type the correct commands, otherwise, the operation will fail or the wrong files will be deleted.

Way 3. Via a third-party file deletion tool
