RemoveLocalOneDriveFiles.ps1

<#
.SYNOPSIS
    Removes local copies of OneDrive files while keeping them online.

.DESCRIPTION
    This script goes through your OneDrive folder and removes the local copies of files by marking them as "Online-Only" using the `attrib` command. This frees up disk space without deleting the files from the cloud.
