I work with multiple projects, and I want to recursively delete all folders with the name 'bin' or 'obj' that way I am sure that all projects will rebuild everything (sometimes it's the only way to force Visual Studio to forget all about previous builds).
Is there a quick way to accomplish this (with a .bat file for example) without having to write a .NET program?
This question is related to

from Using Windows PowerShell to remove obj, bin and ReSharper folders
very similar to Robert H answer with shorter syntax
paste and run below script
dir .\ -include bin,obj,resharper* -recurse | foreach($) { rd $_.fullname –Recurse –Force}
I wrote a powershell script to do it.
The advantage is that it prints out a summary of deleted folders, and ignored ones if you specified any subfolder hierarchy to be ignored.
Is 'clean' not good enough? Note that you can call msbuild with /t:clean from the command-line.
Considering the PS1 file is present in the currentFolder (the folder within which you need to delete bin and obj folders)
$currentPath = $MyInvocation.MyCommand.Path
$currentFolder = Split-Path $currentPath
Get-ChildItem $currentFolder -include bin,obj -Recurse | foreach ($_) { remove-item $_.fullname -Force -Recurse }
Nothing worked for me. I needed to delete all files in bin and obj folders for debug and release. My solution:
1.Right click project, unload, right click again edit, go to bottom
2.Insert
<Target Name="DeleteBinObjFolders" BeforeTargets="Clean">
<RemoveDir Directories="..\..\Publish" />
<RemoveDir Directories=".\bin" />
<RemoveDir Directories="$(BaseIntermediateOutputPath)" />
</Target>
3. Save, reload project, right click clean and presto.
To delete bin and obj before build add to project file:
<Target Name="BeforeBuild">
<!-- Remove obj folder -->
<RemoveDir Directories="$(BaseIntermediateOutputPath)" />
<!-- Remove bin folder -->
<RemoveDir Directories="$(BaseOutputPath)" />
</Target>
Here is article: How to remove bin and/or obj folder before the build or deploy
I found this thread and got bingo. A little more searching turned up this power shell script:
Get-ChildItem .\ -include bin,obj -Recurse | ForEach-Object ($_) { Remove-Item $_.FullName -Force -Recurse }
I thought I'd share, considering that I did not find the answer when I was looking here.
This is my batch file that I use for deleting all BIN and OBJ folders recursively.
@echo off
@echo Deleting all BIN and OBJ folders...
for /d /r . %%d in (bin,obj) do @if exist "%%d" rd /s/q "%%d"
@echo BIN and OBJ folders successfully deleted :) Close the window.
pause > nul
This worked for me:
for /d /r . %%d in (bin,obj) do @if exist "%%d" rd /s/q "%%d"
Based on this answer on superuser.com
Very similar to Steve's PowerShell scripts. I just added TestResults and packages to it as it is needed for most of the projects.
Get-ChildItem .\ -include bin,obj,packages,TestResults -Recurse | foreach ($_) { remove-item $_.fullname -Force -Recurse }
Here is the answer I gave to a similar question, Simple, easy, works pretty good and does not require anything else than what you already have with Visual Studio.
As others have responded already Clean will remove all artifacts that are generated by the build. But it will leave behind everything else.
If you have some customizations in your MSBuild project this could spell trouble and leave behind stuff you would think it should have deleted.
You can circumvent this problem with a simple change to your .*proj by adding this somewhere near the end :
<Target Name="SpicNSpan"
AfterTargets="Clean">
<RemoveDir Directories="$(OUTDIR)"/>
</Target>
Which will remove everything in your bin folder of the current platform/configuration.
We have a large .SLN files with many project files. I started the policy of having a "ViewLocal" directory where all non-sourcecontrolled files are located. Inside that directory is an 'Inter' and an 'Out' directory. For the intermediate files, and the output files, respectively.
This obviously makes it easy to just go to your 'viewlocal' directory and do a simple delete, to get rid of everything.
Before you spent time figuring out a way to work around this with scripts, you might think about setting up something similar.
I won't lie though, maintaining such a setup in a large organization has proved....interesting. Especially when you use technologies such as QT that like to process files and create non-sourcecontrolled source files. But that is a whole OTHER story!
I think you can right click to your solution/project and click "Clean" button.
As far as I remember it was working like that. I don't have my VS.NET with me now so can't test it.
For the solution in batch. I am using the following command:
FOR /D /R %%G in (obj,bin) DO @IF EXIST %%G IF %%~aG geq d RMDIR /S /Q "%%G"
The reason not using DIR /S /AD /B xxx
1. DIR /S /AD /B obj
will return empty list (at least on my Windows10)
2. DIR /S /AD /B *obj
will contain the result which is not expected (tobj folder)
This Works Fine For Me: start for /d /r . %%d in (bin,obj, ClientBin,Generated_Code) do @if exist "%%d" rd /s /q "%%d"
Command line tool that finds Visual Studio solutions and runs the Clean command on them. This lets you clean up the /bin/* directories of all those old projects you have lying around on your harddrive
I use .bat file with this commad to do that.
for /f %%F in ('dir /b /ad /s ^| findstr /iles "Bin"') do RMDIR /s /q "%%F"
for /f %%F in ('dir /b /ad /s ^| findstr /iles "Obj"') do RMDIR /s /q "%%F"
I use a slight modification of Robert H which skips errors and prints the delete files. I usally also clear the .vs
, _resharper
and package
folders:
Get-ChildItem -include bin,obj,packages,'_ReSharper.Caches','.vs' -Force -Recurse | foreach ($_) { remove-item $_.fullname -Force -Recurse -ErrorAction SilentlyContinue -Verbose}
Also worth to note is the git
command which clears all changes inclusive ignored files and directories:
git clean -dfx
A very quick and painless way is to use the rimraf
npm utility, install it globally first:
> npm i rimraf -g
And then the command from your project root is quite simple (which can be saved to a script file):
projectRoot> rimraf **/bin **/obj
To optimize the desired effect you can leverage the project event targets (the one you could use is BeforeRebuild
and make it run the previous command) which are specified in the docs: https://docs.microsoft.com/en-us/visualstudio/msbuild/how-to-extend-the-visual-studio-build-process?view=vs-2017
I like the rimraf utility as it is crossplat and really quick. But, you can also use the RemoveDir
command in the .csproj if you decide to go with the target event option. The RemoveDir
approach was well explained in another answer here by @Shaman: https://stackoverflow.com/a/22306653/1534753
On our build server, we explicitly delete the bin and obj directories, via nant scripts.
Each project build script is responsible for it's output/temp directories. Works nicely that way. So when we change a project and add a new one, we base the script off a working script, and you notice the delete stage and take care of it.
If you doing it on you logic development machine, I'd stick to clean via Visual Studio as others have mentioned.
I use to always add a new target on my solutions for achieving this.
<Target Name="clean_folders">
<RemoveDir Directories=".\ProjectName\bin" />
<RemoveDir Directories=".\ProjectName\obj" />
<RemoveDir Directories="$(ProjectVarName)\bin" />
<RemoveDir Directories="$(ProjectVarName)\obj" />
</Target>
And you can call it from command line
msbuild /t:clean_folders
This can be your batch file.
msbuild /t:clean_folders
PAUSE
Have a look at the CleanProject, it will delete bin folders, obj folders, TestResults folders and Resharper folders. The source code is also available.
You could actually take the PS suggestion a little further and create a vbs file in the project directory like this:
Option Explicit
Dim oShell, appCmd
Set oShell = CreateObject("WScript.Shell")
appCmd = "powershell -noexit Get-ChildItem .\ -include bin,obj -Recurse | foreach ($_) { remove-item $_.fullname -Force -Recurse -WhatIf }"
oShell.Run appCmd, 4, false
For safety, I have included -WhatIf parameter, so remove it if you are satisfied with the list on the first run.
Something like that should do it in a pretty elegant way, after clean target:
<Target Name="RemoveObjAndBin" AfterTargets="Clean">
<RemoveDir Directories="$(BaseIntermediateOutputPath)" />
<RemoveDir Directories="$(TargetDir)" />
</Target>
I actually hate obj files littering the source trees. I usually setup projects so that they output obj files outside source tree. For C# projects I usually use
<IntermediateOutputPath>..\..\obj\$(AssemblyName)\$(Configuration)\</IntermediateOutputPath>
For C++ projects
IntermediateDirectory="..\..\obj\$(ProjectName)\$(ConfigurationName)"
