Drive visibility

Catch disk-full outages before they catch you

Query every drive, volume, and partition on any remote Windows machine — size, free space, free %, file system, and label. Spot the C: drive at 95% capacity before it crashes a production server or breaks a user's day. Run it on demand against one machine or your entire fleet, and act with hard data instead of guesswork.

From download to first result in five simple steps. No complex configuration, no firewall rules, no additional licensing.

  1. 1

    Install Free Windows Admin Tools

    Install the bundle on your admin workstation. Lightweight, no license key required, and ready to use in under two minutes.

    Requirement: Install only on the admin's machine — target computers need nothing installed.
  2. 2

    Open Disk Space Detector from the sidebar

    Click Disk Space in the left sidebar of the unified console. The tool loads instantly alongside the other 14 utilities.

    Tip: Bookmark this tool for your weekly capacity audits.
  3. 3

    Pick your Windows domain

    All domain-joined computers populate automatically from Active Directory — no CSV imports, no IP lists to maintain.

    Multi-domain? Start with your file servers — they're usually the first to fill up.
  4. 4

    Single PC or bulk audit

    Pick one machine for a focused check, or Ctrl-click multiple computers for a fleet-wide storage audit in a single operation.

    Best practice: Audit your entire 'Servers' OU before quarterly capacity planning.
  5. 5

    Identify drives needing attention

    Sort by free % to surface critical drives. Plan cleanups, upgrades, or migrations based on hard data instead of guesswork.

    Going further: For automated low-disk alerts and storage analytics, see Endpoint Central (free for 25 endpoints).

Built for real IT admin scenarios

Server capacity planning

Audit your file servers, application servers, and database hosts on a schedule. Plan upgrades before users start complaining about slow saves or failed writes.

Identify users whose drives are choking on temporary files, downloads, and old profiles. Target your cleanup efforts where they matter.

Pre-migration storage audit

Before a cloud migration or hardware refresh, baseline storage across your fleet to size new infrastructure accurately — no over- or under-provisioning.
