How To Identity Large Files Using DiskUsage Command?

Lack of storage space is one of the most frequent issues faced by all PC users. You can refine the data displayed in DiskUsage based on file size. Therefore, you can configure it to ignore smaller files if, for instance, you only want to include files larger than 500MB. To identify large files and sort them, we can use the following commands using the DiskUsage tool.

Step 1: You must add the minFileSize option to the command if you want to only include files larger than a particular size.

DiskUsage /minFileSize=6553600 C:\Users\Username\OneDrive\Pictures\Screenshots /h

Step 2: Only files greater than 500MB will appear in the result. You might need to use an online conversion tool to convert MB to Byte because the file size value must be provided in bytes.

Step 3: Add the “/u=10” command to list the top ten largest files in a particular folder.

DiskUsage/minFileSize=6553600 C:\Users\Username\OneDrive\Pictures\Screenshots /h /u=10


The Command Prompt window will now provide a list of the 10 largest files in the Screenshots folder.
