Get FIle Size using PowerShell

We can make use of the Get-Item cmdlet from the Microsoft.PowerShell.Management module to get the size of a file.

Let's take a look at a few one-liner examples.

Example 1: For a File

(Get-Item 'data_2023.csv').Length

16147

Example 2: For a File with Absolute Path

(Get-Item 'D:\documents\annual_report.xlsx').Length

1211234

Example 3: Convert File Size from Bytes to KB/MB

"{0:N2} {1}" -f ((Get-Item 'sharepoint.png').Length / 1MB), "MB"

0.02 MB

Example demonstrated on macOS with Powershell version 7.2
