BLOG: Determine and modernize Filesystem Deduplication

"Map workloads that create many small or rapidly changing files"

Q: I have a received the question: How can I identify the workload size and inventory?

A: On Windows Server / Windows Server Core I trust using a third-party solution named JAMSoftware TreeSize.  Please consider the license terms for business use.

You can install Treesize on a management host (privileged access workstation) to remotely access the file systems of different servers. 

Treesize provides swift reports and diagrams. It provides detailed information on the number of files, sizes, potential space hogs and unexpected archives, as well as parameters such as the last access date and last change. A free version is available through the Winget repository and the Microsoft Store.

PS C:\Users\username> winget search treesize
Name          Id                        Version Source

TreeSize      XPDDXV3SD1SB5K            Unknown msstore
TreeSize      JAMSoftware.TreeSize      9.6.2   winget
TreeSize Free JAMSoftware.TreeSize.Free 4.8.1   winget

Of course one can achieve similar via PowerShell, yet I found the GUI output and reports overly helpful.
