List files that are in the TFS repository but not in the Visual Studio solution - visual-studio

Question

We have big solution(300+ projets), which is evolving since a long time(7 years), and over the time, there has been a lot of refactoring(projects removed, moved, ...). We did notice that sometimes when some projects are deleted from the solution, they are not deleted from the solution, and also that we have some leftover files.
We would like to find all those kind of files in order to delete most of them(not all).
Is there a way to list all those files?
(We have Visual Studio 2015 enterprise)

Answer 1

Check this PowerShell script from this case, which should do what you are looking for. It parses the project file to get the included code files. Then it compares that list to the actual files on disk. The remaining files are your unused/obsolete files.
The script can either delete the unused files from disk or pend them as deletes in TFS.
<#
.SYNOPSIS
Find and process files in a project folder that are not included in the project.
.DESCRIPTION
Find and process files in a project folder that are not included in the project.
Options to delete the files or to add them as pending deletes for TFS. Use TF.exe to pend the deletes and start the check-in process for the files.
This is necessary when trying to delete files that are not currently included in a Visual Studio project.
.PARAMETER Project
The path/name for the project file.
.PARAMETER VsVersion
The Visual Studio version (10, 11, 12). Used to locate the tf.exe file.
.PARAMETER DeleteFromDisk
Just delete the files from disk. No interaction with any source control.
.PARAMETER TfsCheckin
After pending the deletes, open the check-in dialog.

Also, other community members expend this script and share the scripts at:
#Marc Climent: I used this script to create a more detailed one that includes other types of files and does not use TFS: https://gist.github.com/mcliment/d9008a9288cea9d088af
#mikesigs: I too used this file as well as #MarcCliment's to create yet another PowerShell script that takes a .sln file instead of a single proj file. It deletes all files excluded from all projects in the provided solution: https://gist.github.com/mikesigs/3512dbccc1767d447977#file-deleteexcludedfiles-ps1
