Key Points

Establish a standardized PowerShell workflow for auditing file server storage capacity, identifying duplicate files, and assessing access control list (ACL) configurations.
Assessed disk usage, recorded access denials, and identified redundant files using cryptographic hash comparisons.
Audited permissions and identified broken access inheritance structures using the Get-Acl cmdlet.
Constructed CSV reporting routines and established safety procedures for applying permission changes via icacls and Set-Acl.
Automated the extraction of capacity metrics and duplicate file candidates across enterprise directory structures.
Identified permission discrepancies and broken inheritance hierarchies across audited file trees.
Defined a structured change-control methodology to prevent permission corruption during Set-Acl and icacls executions.

Abstract

A practical procedure for taking inventory of a file server with PowerShell. Covers capacity analysis and recording access denials, listing old files and extracting duplicate candidates by hash, permission auditing with Get-Acl and detecting broken inheritance, producing CSV reports, choosing between icacls and Set-Acl, and a safe change procedure for Set-Acl.
