How to uninstall TeraCopy on Windows

TeraCopy keeps its copy history, ignore list, scripts and options in your profile, and none of it matters to the files you copied, which stay where you put them. Back up %APPDATA%\TeraCopy if you want your options and history after a reinstall. This guide covers TeraCopy installed machine-wide with the vendor's installer from the CodeSector.TeraCopy winget manifest. That installer registers two things: the TeraCopy program itself, a Windows Installer (MSI) product in Program Files\TeraCopy, and a small per-user package, TeraCopy Shell Extension, that adds TeraCopy to File Explorer's right-click menu.

Quit TeraCopy first

Let any running copy finish, then close the TeraCopy window. Check Task Manager (Ctrl+Shift+Esc) for any TeraCopy.exe still listed before you uninstall. TeraCopy added no startup item in this test.

Remove the app with its own uninstaller

Go to Settings › Apps › Installed apps, find TeraCopy, and choose Uninstall, or run:

winget uninstall --id CodeSector.TeraCopy

The Windows Installer product was installed for all users, so it asks for administrator access. Afterwards check that the shell extension package is gone too (see below); if it is still registered, Mole lists it as TeraCopy Shell Extension.

Where the data lives

These locations were observed in testing while TeraCopy was installed.

Location	What it holds	What to do
`Program Files\TeraCopy`	Program files and the bundled updater	Left to the TeraCopy uninstaller; this test did not run it, so check afterwards
`%APPDATA%\TeraCopy`	History, ignore list, scripts and `Options.ini`	Back it up if you want the same options; otherwise remove it
`%ProgramData%\Code Sector\TeraCopy`	Data the installer keeps for all users	Safe to remove once TeraCopy is gone; leave `Code Sector` itself if another Code Sector app is installed
`%LOCALAPPDATA%\Packages\TeraCopy_dh7b2k9690c90`	Data container of the shell extension package	Goes with the package
`%USERPROFILE%\.obs64`, `%APPDATA%\Obsidium x64` and `HKCU\Software\Obsidium x64`	License protection data written by TeraCopy's copy protection	Only the entries this install wrote are TeraCopy's; another program protected the same way writes there too, so look before removing
`HKCU\Software\Caphyon\Advanced Updater`	Settings of the updater TeraCopy ships	Caphyon's updater is used by other apps as well; leave the `Caphyon` key alone

Check the result

Run these read-only commands after the uninstall finishes:

Get-Process TeraCopy -ErrorAction SilentlyContinue
winget list --id CodeSector.TeraCopy
Get-AppxPackage -Name TeraCopy
Test-Path "$env:ProgramFiles\TeraCopy"
Test-Path "$env:APPDATA\TeraCopy"
Test-Path "$env:ProgramData\Code Sector\TeraCopy"

No output from Get-Process only means this query observed no matching process; a suppressed error leaves the running state unknown.
A completed winget list query with no match means the TeraCopy entry is gone; a matching row means the uninstall did not finish.
If Get-AppxPackage succeeds without suppressed errors, no output means the shell extension package is gone; a result means it is still registered for your account.
Test-Path "$env:ProgramFiles\TeraCopy" returning False means the program folder is gone; True means files remain there.
The last two returning True mean your options and history, and the shared data, are still there, which is expected unless you removed them yourself.

What Mole lists

For TeraCopy installed machine-wide with the vendor's installer:

The shell extension package appears as its own app, TeraCopy Shell Extension. Its data container goes with the app row, and Mole removes the package for your account without an administrator prompt.
Program Files\TeraCopy, %APPDATA%\TeraCopy, %ProgramData%\Code Sector\TeraCopy and the Obsidium entries were not listed in this test.
Machine-wide registry keys and the checksum file types TeraCopy registers under HKLM are never listed.

What this test covered

Tested on 2026-09-28 with TeraCopy 4.0.3.2 installed machine-wide from the vendor's installer in the winget manifest. Mole's list showed only the shell extension package at the time, so this test removed that package and its data container; the TeraCopy program and its Windows Installer entry stayed installed. Not verified: removing the main program through Mole, a licensed install, or an x64 PC.
