Unable to copy file - access to the path is denied

Question

I am using Visual Studio 2005  After taking code from version control first    the c  net application runs correctly  But  after doing some modifications  when I build I am getting the following error      Error  383 Unable to copy file     root leaf Bin Debug test Resources xml  to        Bin Debug test Resources xml   Access to the path  Bin Debug test Resources xml  is       denied  li rollmodel   Does anybody know why this issue is occurring   Edit I can see that my entire project source code folder is Read-only  and I am not able to remove the read-only property   First  can anybody tell me how to remove the Read-only property for this folder  I have tried removing it but the read-only property persists  I tried from the version-control side also and that did not work  either

Old post  but this zombie is hitting VS 2017  I haven t dug into why it s just  some  projects   In this case  it s not user permissions  rather IIS Express process is still using the files    You ll see the icon in your task tray    Right Click Exit You should be able to rebuild without this annoying  permission denied  message    This is also why  restarting Visual Studio  will  fix  the issue  Doing so  stops IIS Express   Hth

I created this problem when I added a new setup project to the solution  and then added files directly from the  bin release folder of the main application project to the application files folder of the setup project   The source control of the setup project was consistently blocking me from completing a build of the main application project   Solution  create a separate dump folder outside of any of the projects that will contain all the files to be included in the install  and add them from there   It s a pain because now I have to remember to copy all the files for each new install package   I might see if I can do something with post-build actions our an automated build to make the process smoother

I solved this problem by deleting the contentious files from bin folder and rebuilding the project

User · Answer

For me the issue was that another project in the solution had the same  dll file which had been checked in more recently     Manually copying the more recently checked in version of the  dll from the other project bin folder to bin folder in the project that was generating the error fixed the problem   A longer term fix for our solution would be to use the same exact  dll for all projects in the solution instead of having the same  dll file in multiple projects but I didn t feel like tackling that so the quick-and-dirty solution was to just copy over the newer version

Check Task Manager and make sure you don t have a devenv exe process hanging  Kill the runaway process and try again

User · Answer

You aren t supposed to change the folder attribute to not-readonly  The reason you are seeing this error message is that source control assumes that you only store your miscellaneous files somewhere other than bin folder  for it it reserved for files that are automatically created by  Net and it doesn t want to add them to source control   I suggest instead of using Environment CurrectDirectory  which I assume you are using currently   you create a folder named  MyProjectName  in  appdata  address and then use   System IO Path Combine Environment GetEnvironmentVariable  appdata    YourProjectName

Most of the answers I have seen are objectively exploring possible issues with the environment  which is probably correct for 99  of the people running into this issue  unable to copy file from     to     access is denied   I thought I should share my experience for the 1  who ran into this problem due to misc reasons  I wrote a batch file renaming program that i use to act on tens of thousands of files  and my AntiVirus interpreted it as trojan and auto quarantined it  Having this path sit in my AntiVirus  blacklist  visual studio can never copy the   exe into the bin folder  hence resulting unable to copy  exe  My resolution is to whitelist this path and the issue is resolve  Cheers

Had the same problem  but restarting Visual Studio every time was no option for me  as the issue occurs sometimes very often   I handled it by installing Unlocker  tries to install any toolbar at installation  so don t forget to uncheck this   this application gives me fast access to rename delete a locked   xml -File  I know that this only a workaround too  but for me it was the fastest solution to solve this problem

I use Visual Studio 2013  I faced this problem 2 times    On first occasion  I was running Visual Studio without Administrator rights  So  I closed VS and started it using  Run as administrator  option  This solved my problem  On second occasion  I restarted VS many times  every time making sure that I am running it as an administrator  Also  I rebuilt solution many times  But  in spite of that I was getting error   After that  I removed the concerned file from the target location  the file was already present may be from the previous build at the location where it tries to copy to  and rebuilt the solution  After that  error went away and everything ran smoothly

I had the same issue  To resolved this i had checked done several things  What Didn t work  1  Read write permissions were given to directory  2  Restarted visual studio 3  Tried deleting visual studio temp files   What worked at last  Just paste the command given by Fred Morrison into the  Package Manager Console    Get-Process   Where-Object -Property Name -EQ  VBCSCompiler    Stop-Process -Force -Verbose   Note  Just an observation Restarting Visual studio might not work in this case but restarting system can because stoppin process  VBCSCompiler  was the solution so we can do it either way

This can be a strange by-product of loading source initially from source control  TFS etc   where all files and folders are write protected   Go to the top level directory and check the properties and you could find the Read-only attribute checked   Uncheck that and the system should ask you if you want all the dirs under the top level to be set the writable  This should fix it

Can any body know why this issue is coming    Looking at your response that you resolved your problem by manual copying  I would say that the code you were working on was made by some other user  with administrator privileges too  so it was locked to you  By performing copy --  paste  you made your OWN copy of the source with all access you required  The only thing to notice is that  in this case if this other developer will need to work on your copy  he she will jump in pretty same problem you got before

Just make sure that the folder is NOT Read-Only and rebuild the solution

User · Answer

I stepped into this problem too   First go and check if you have mapped your bin and obj folder to the Source Control program   This may be turning your files from binaries folders into read only archives  which make impossible to visual studio to overwrite them when it compiles the code   Go and remove the mapping from these folders  check the changes and try again   My problem occurred using TFS Team foundation server  and Visual Studio 2010   Hope this helps someone

I tried everything here  somehow deleting all the bin and obj folders in my project didn t work  Releasing the folders from other processes did nothing  Restarting did nothing  Removing read only from every file by unchecking it on the main folder didn t help   Every dependency ended up adding themselves to the problem  Building directly in the dependencies  folder worked so I was confused  I was going to duplicate this question but I found something that worked   You know what worked   dotnet clean

This has reared it s head again in Visual Studio 2017  in this case the cause is the Application Insights process ServiceHub DataWarehouseHost exe   There is a workaround discussed in the thread warning MSB3026  Could not copy  obj Debug netcoreapp1 1 src pdb  to  bin Debug netcoreapp1 1 src pdb   which is to add a pre-build event to the project to kill the process every time the project is built   Quoting from that link         Right click properties on project    Choose properties    Build Events   Pre-build event command line       taskkill  IM ServiceHub DataWarehouseHost exe  F 2 gt nul 1 gt nul Exit 0         Save and build
