TFS: How can you Undo Checkout of Unmodified files in a batch file

We use a batch file to generate code, and it automatically checks out the generated files from Team Foundation Server (TFS) so that it can regenerate them. The majority of these files are not modified, but the generator does not know this ahead of time.

The "tfs undo" command undoes the checkout, but prompts if some have been modified (which we don't want to do). We also do not want to check in the generated files right away.

Is there a command (or series of commands) to undo checkout of all unmodified files without prompting the user?

Note that manually undoing all changes with the expectation of choosing "No to all" when prompted about files that have changed will not work correctly, as it will undo ADD changes without prompting (see Ray's answer).

Take a look on Undo Unchanged command of the Team Foundation Server Power Tools August 2011

c:\myProject> tfpt uu . /noget /recursive

Thanks Matt Florence for link update.

Thanks Ray Vega for actual syntax.


This should be edited / merged to contain the usage information as part of the answer content.
You really want to read this post: aaubry.net/undo-checkout-on-unchanged-files-tfs.html
hmm, somehing that almost everyone does several times daily: "Lets put it in a separate installer called Power Tools"... sigh
@Mike Chaliy you would think. I'm trying out TFS right now, and was searching on how to do this and ended up here.
It doesn't work if your changes are merges. It seems tfpt uu always considers a merge to be a real change, even if there is no file change, and there's no option to flip that behaviour. It's ok as a default behaviour, but sometimes it's not what you want.

Install Team Foundation Server Power Tools and run the following from the command line using tfpt.exe at the root of your project's workspace directory:

c:\myProject> tfpt uu . /noget /recursive

Including /noget is highly recommended since it prevents a forced 'get latest' of all your project's files which depending on the total number can take a extremely long time.


This should be the accepted answer, it has all the relevant details (as proved by the higher score).
Cool. Also, why not add this as a permanent 'External Tool' to Visual Studio. Taking this as an example: blog.kurtschindler.net/post/… Command: [your installation dir]\TFPT.EXE Arguments: uu . /noget /recursive Initial directory: $(SolutionDir)
The question specifies doing this operation without the prompt, but none of the answers seem to address this. If you need this, the additional /noprompt is the option you're looking for. The PowerTools documentation is missing this! It lists this option for a few of the commands, but not this one (UU). Beware!
@user20358 either cd to where your workspace directory is (for example, mine was c:\myProject) or explicitly include it after uu (replacing the period . with it)
Does this have a force switch, like /Y or /force? I'm always asked if really want to undo it, and I'd like to have that automated. Put /Y there, but it tells me The Option Y requires a value.

Thank you @mike & @ray,

I wish to make it easier.

In VS, at Tools menu, click on "External Tools".

Click Add.

Enter title.

Command: tfpt.exe

Arguments: uu . /noget /recursive

Initial Directory: [you can choose from the arrow button].

Two new command are added to Tools menu.

Use them when needed.

Enjoy,

Ofir


Very cool. You can go one step further too and add a shortcut. Note how far down your added command is (e.g. it may be the fourth). Then to to Tools -> Options -> Environment -> Keyboard -> and type in the 'Show commands containing' textbox "Tools.External" and assign a shortcut. For instance I selected Tools.ExternalCommand4 since my newly added undo command was the fourth one down. I then assigned shortcut keys Ctrl + Alt + U, Ctrl + Alt + U
Could we please have an updated version of this? If found tf.exe but what is uu command? it tells me Unrecognized command: uu. Thanks for help
@Shay : Works for me in VS2015 with the latest TFS power tools installed.

Right-click on your project Select undo checkout, then just click okay, or whatever confirmation is left... Then, while undoing checkout, for every file that has REAL changes in it, a prompt will ask you to confirm the check out for that file... simply click "No to All"

Visual studio will know if the checked out file has changes or none.

WARNING: This method also removes new files, i.e. files that are not yet checked in to TFS. If you want to keep these files then simply exclude them from the set of files you "undo".


Be aware that this method also removes added files that are not yet checked in from TFS. ... yeah, that's a pretty immediate disqualifier.
It works for mine Baseless branches merge. Thanks. Usually in this case VS marked All files in solution as changed.
this is a hell when nuget do checkout for a 10000 files that are not required to be updated.

Updated this question with an answer when working with TFS2017 and VS2017/VS2019 only.

The power tools does not exist for TFS 2017 and the old ones can't work well together with it, but apparently most of the functionality has been moved to VS2017 itself or plugins (see below).

Visual Studio 2017/2019 Extension

Some actions like undo unchanged files have moved to an

extension for VS2017

extension for VS2019

"Undo Unchanged" button location:

Known bug

You have to open the 'Source Control Explorer' (and leave it open) so that the 'Undo Unchanged' is displayed in the Action menu of the Pending Changes view. reported here.

Windows Shell Integration Extension

Also, you can still set up Windows shell integration through an separate installer which is no longer linked to TFS Power Tools.

The windows shell integration do not work exactly the same as the powertools before, but the most important actions worked for me.


I noticed in the question, that they want to script it, for that I don't have a solution, I'm afraid
I can't find the "Undo Unchanged" option in VS2017 after installing the linked extension. Did I miss something ?
I haven't used it very much. When I used it to test it for my customer, I had to click around a bit in Team Explorer and make sure that there were changes to undo. It's possible that it only appears when you only have pending changes queued for a commit that this option appears. ( or one branch changes only)...
@Erzékiel The option appears only when Solution Explorer is open and ready.
This extension works sometimes and its presence is linked to having the TFS Source Control Explorer open and not Solution Explorer (as some wrongly pointed out) - do not mix up the two different control windows. However; when I say sometimes, its because it comes and goes. Right now I dont have it, I did a month ago. Its a tiny bit buggy and I fear other extensions is the culprit, such as Resharper and the like.

If you simply check all the files back in again that you checked out, TFS is smart enough to figure out which ones changes and only include them in the changeset that is recorded on the server.

TFS does this by comparing MD5 hashes of the files contents before and after check-in.

This is all assuming that your generation process is purely updating the same set of files, i.e. you will never have the case where a file that was generated in a previous generation is not needed in the next generation (i.e. you would want to pend a delete for that file) or that the files change name.

If your process could potentially need files deleting, the your best bet might be to look at the Team Foundation Power Tools command (tfpt) and use the tfpt online command that will only check out the files that have changed, and will be smart enough to pend deletes for any files that are no longer needed or changed name and pend adds.

Good luck,

Martin.


Thanks for that, however we do not want to check in the modified files at that time. The modified ones should not be checked in till the feature is done, but the unmodified ones should be removed so the dev can review the changes.
@RobertWagner If you have a gated build, then you can cancel (if it doesn't abort upon identical file detection) when you get the popup alert that the changes have to be built first.

Beware that TFS undo will not revert back the File System's "Date Modified" value. This is very frustrating especially if you use tools like robocopy to sync up remote machines. Even after you undo your check out, if you saved the file thereby updaing the "Date Modified" value, that updated value will stick around even after an undo checkout.


Either use robocopy or a VCS, using a mixture is always going to give inconsistencies. Much better would be to populate each machine from VCS directly.

There are a couple of points regarding the uu option for tfpt (recommended in most of the other answers) that were not clear to me at first. Firstly, this is the command line help that can be accessed with the command tfpt uu /?

Undoes redundant pending changes. If the state of an item with a pending change is the same as on the server, then the change is undone. Usage: tfpt uu [/changeset:changesetnum] [/recursive] [/noget] [filespec...] /changeset Compare the workspace to item states at the changeset version specified instead of the latest version filespec... Only check the listed filespecs for redundant changes /recursive Check the specified filespecs with full recursion /noget Do not run get before checking The /changeset option may not be used with filespecs or /recursive.

Now let me break down the command that is recommended in the other answers.

tfpt uu . /noget /recursive

tfpt uu specifies that we wish to use the 'Undo Unchanged' command.

. indicates (I guess) that the current working directory should be used as the filespec.

/noget ensures that 'get latest version' is not called before undoing the unchanged files.

/recursive ensures that not just the filespec will be considered but all recursive child folders and files. This seems to be dependent on the filespec - if there is none provided then the whole workspace is processed.

So there are a couple of things to note here regarding the command from above...

It is dependent on the working directory.

It does not process the entire workspace.

I have found that the following command works best for me - it will process the entire workspace.

tfpt uu /noget

Note that it is still dependent on the working directory in that tfpt uses it to determine which workspace should be processed. But as long as you provide a path to a file or folder within the workspace, you are good to go.

I can see Ray LionFang's approach above. Can't comment there since I don't have the rep. While I like this approach since there's no changes required to Tools etc........

Right-click on your project select undo checkout, then just click okay, or whatever confirmation is left... then, while undoing checkout, for every file that has REAL changes in it, a prompt will ask you to confirm the check out for that file... simply click "No to All" Visual studio will know if the checked out file has changes or none. Be aware that this method also removes added files that are not yet checked in from TFS...

.......there's a problem with that approach in that hitting "No To All" retains a few files which are not modified. It seems to do something like Undoing unmodified files until it hits the first file that's actually modified and then ignores the rest of the unmodified files, if that makes any sense. I've only seen this effect once in a while.

A potential work-around is to follow the above process but instead of hitting "No To All", hit "No" for each file. Since this can take a while depending on the number of files you're working with, what I normally do is to hold down "ALT + N", and it just speeds through all the files while undoing ALL unmodified files.


please be advised as this cannot be emphasised enough. Newly added files to the project are also removed with this approach. This is mentioned on serveral of the other answers as well.

As far as I understood, in TFS if you checkout a team project, the whole project is checked out and you do not have control of which files are brought down. If you want to prevent checkins to certain files, you can lock them.

At work, we all hate TFS.


We can check out individual files, and locking it would not allow the developer to check them in.
Was going to down vote, but "At work, we all hate TFS." saved it.
