NOTE: This applies to both open source and commercial editions of Chocolatey.

1. Ensure you are set for organizational deployment

Please see the organizational deployment guide

  • Open Source or Commercial:
    • Proxy Repository - Create a proxy nuget repository on Nexus, Artifactory Pro, or a proxy Chocolatey repository on ProGet. Point your upstream to Packages cache on first access automatically. Make sure your choco clients are using your proxy repository as a source and NOT the default community repository. See source command for more information.
    • You can also just download the package and push it to a repository Download

3. Enter your internal repository url

(this should look similar to

4. Choose your deployment method:

choco upgrade finddupe -y --source="'STEP 3 URL'" [other options]

See options you can pass to upgrade.

See best practices for scripting.

Add this to a PowerShell script or use a Batch script with tools and in places where you are calling directly to Chocolatey. If you are integrating, keep in mind enhanced exit codes.

If you do use a PowerShell script, use the following to ensure bad exit codes are shown as failures:

choco upgrade finddupe -y --source="'STEP 3 URL'"

Write-Verbose "Exit code was $exitCode"
$validExitCodes = @(0, 1605, 1614, 1641, 3010)
if ($validExitCodes -contains $exitCode) {
  Exit 0

Exit $exitCode

Finddupe is a tool for quick detecting of duplicate files on a hard drive under Windows. Duplicate files can be detected, hardlinked, or deleted. Finddupe can also search for hardlinked files on your computer.

Finddupe is a command line program. If you arent familiar with the "command prompt" under windows, this program might be a little challenging for you to use.

Finddupe has several possible uses:

Deleting duplicate files
When working thru somebody elses photo collection, or MP3 collection, this tool is useful for deleting the files that are duplicate. Depending on how the media is organized, there can be a lot of duplicate files in a collection.

Freeing hard drive space
Sometimes its intentional to have certain media in multiple places. By running finddupe, and hard linking the identical files, you can keep the files in multiple places, while only having one physical copy on the hard drive.

Detecting changed files for backup
Finddupe is useful for detecting which files have changed and need backing up. Simply back up the media, and then run finddupe to eliminate those files in the copy that are already contained in a previous backup.

Detecting hardlinked groups of files
Unknown to most, the winodws NTFS file system has the ability to hard link files together. If you use finddupe with the -listlink option, finddupe will search for files that appear in multiple places as hard links.

Source code:

try {
	$packageName = 'finddupe'
	$packageVersion = '1.23'
	$url = ''
	$installDir = "$(Split-Path -parent $MyInvocation.MyCommand.Definition)"
	$installFile = Join-Path $installDir "$($packageName).exe"
	Get-ChocolateyWebFile "$packageName" "$installFile" "$url"
	Install-ChocolateyPath "$nodePath" 'Machine'  # Machine will assert admin control
	Write-ChocolateySuccess "$packageName"
} catch {
	Write-ChocolateyFailure $packageName $($_.Exception.Message)

In cases where actual malware is found, the packages are subject to removal. Software sometimes has false positives. Moderators do not necessarily validate the safety of the underlying software, only that a package retrieves software from the official distribution point and/or validate embedded software against official distribution point (where distribution rights allow redistribution).

Chocolatey Pro provides runtime protection from possible malware.
