Placeholder install sheet: brackets mark values nobody has recorded.

Warns when the drive letter the install expects has been taken.

pathchief drive --check --letter S
letter S taken by \\fileserver\apps$

Note from the shelf row: none recorded

Before you install

• Runs on: Windows. the application must be 4.0.7 to 4.1.6.
• Space: about 640 KB for the download, plus [WORKING SPACE] while it runs.
• Rights: an ordinary user account; no elevation needed
• Know first: [PREREQUISITE] — what has to be true before this tool will run at all.

Download and verify

Take the build for your platform from the [SHARE] and check it against the digest on the shelf row before you unpack anything.

certutil -hashfile pathchief-3.0-win64.zip

Expected: 964755ea4710. The shelf row carries the same digest.

Install

Copy it into place and put it on the path. Nothing here installs a service or a scheduled task.

Windows

Unpack the zip, then:

xcopy pathchief-3.0-win64 C:\Tools\pathchief /E /I
setx PATH "%PATH%;C:\Tools\pathchief"
pathchief --version

Check it worked

Check the version first, then run the one command the tool exists for:

pathchief --version
pathchief drive --check --letter S
letter S taken by \\fileserver\apps$

Expected output is the line shown above; anything else means [TO DO: write the failure list].

Removing it

Delete the folder and drop the path entry. The tool keeps no state of its own.

rmdir /s /q C:\Tools\pathchief

If it goes wrong

• [KNOWN FAILURE 1] — the usual fixes for this tool have not been written down yet. Add them the second time somebody hits one.
• Wrong error number or a fault you cannot name: run the tool's own diagnostic first (shelf row).
• Before any repair that writes to a store, take the export — backoff is the tool for it.
