What is going wrong when Visual Studio tells me "xcopy exited with code 4"

visual studio xcopy
the command xcopy exited with code 2
visual studio post build copy to output directory
exit code 4 c
visual studio post build copy multiple files
xcopy exit code 4 sccm
tox exited with code 4
batch file error code 4

I'm not very familiar with post-build events, so I'm a little confused as to what's going wrong with my program. When compiling in visual studio 2010, I get the following:

The command "xcopy C:\Users\Me\Path\Foo.bar\Library\dsoframer.ocx C:\Users\Me\Path\Foo.bar\bin\Debug\ /Y /E /D
xcopy C:\Users\Me\Path\Foo.bar\ApplicationFiles C:\Users\Me\Path\Foo.bar\bin\Debug\ /Y /E /D
xcopy C:\Users\Me\Path\url\ C:\Users\Me\Path\Foo.bar\bin\Debug\ /Y /E /D
rmdir /S /Q C:\Users\Me\Path\Foo.bar\bin\Debug\.gwt-tmp" exited with code 4.    

The program appears to run fine, despite this error, but I don't want to just ignore this issue and hope nothing bad happens. Strangely, this line started out as only a single command (the first xcopy) but as I continued to compile the project (fixing other problems, mostly references) the error message expanded larger and larger. Any idea what could be going on?

Edit: Here are the postbuild events that seem to be failing --

xcopy $(ProjectDir)Library\dsoframer.ocx $(TargetDir) /Y /E /D
xcopy $(ProjectDir)ApplicationFiles $(TargetDir) /Y /E /D
xcopy $(SolutionDir)com.myUrl.gwt\www $(TargetDir) /Y /E /D
rmdir /S /Q $(TargetDir).gwt-tmp

Xcopy exit code 4 means "Initialization error occurred. There is not enough memory or disk space, or you entered an invalid drive name or invalid syntax on the command line."

It looks like Visual Studio is supplying invalid arguments to xcopy. Check your post-build event command via Project > Right Click > Properties > Build Events > Post Build Event.

Note that if the $(ProjectDir) or similar macro terms have spaces in the resulting paths when expanded, then they will need to be wrapped in double quotes. For example:

xcopy "$(ProjectDir)Library\dsoframer.ocx" "$(TargetDir)" /Y /E /D1

Switch the watch tab to the "ouput" and look for the xcopy command. Sometimes here you find some more message ( the actual xcopy output ) that could help you to solve the issue. If you don't see the output tab, use View-Output menu to show it.

  • Apart from answers below, also make sure to open VS with Administrator privileges. Copy to specific locations require admin rights.
  • Possible duplicate of Command copy exited with code 4 when building - Visual Studio restart solves it
  • As I said, I don't know much about post-build event scripts (and I didn't write these); where do I find this?
  • Go to project Properties > Build Events
  • Try wrapping each command with double quotes ("command args").
  • @Mark Cidade - I don't seem to have "Build Events" anywhere. Listed Common Properties: "Startup Project; Project Dependencies; Debug Source Files; Code Analysis Settings". Listed Configuration Properties: "configuration".
  • @RavenDreamer: If the $(ProjectDir) (and/or similar) has spaces in the expanded path, then it'll need to be wrapped in quotes. For example: xcopy "$(ProjectDir)Library\dsoframer.ocx" "$(TargetDir)" /Y /E /D1
  • And something you can see if you switch to the output window as @FelicePollano mentioned below.
  • this was my case. i used $(TargetDir) which ends with Release\ . Using $(ProjectDir)\bin\Release without the trailing \\ worked for me
