Deleting file from batch file giving error

I am facing error when i try to delete a file using a batch file. For example say the file i want to delete is "C:\test\a.dll"

i get the folder "c:\test" from regist开发者_如何学JAVAry and then i try to append the file name using and delete it using the following command

del /s %WPINSTDIR%\a.dll

where i get WPINSTDIR from registry and it would be "C:\test"

however when i try to run the batch file i get a error saying network path found and this is the command that is executed. del /s "c:\test"\a.dll

By setting a environment path variable i found that the problem is with the 2 slashes in "c:\test" and the quotes. Anyway to get around this problem.

Thanks

Try using

pushd %WPINSTDIR%
del /s a.dll
popd

This restores the former directory.

You can remove quotes around your environment variable with the following:

%WPINSTDIR:"=%

So the following might work:

del %WPINSTDIR:"=%\a.dll

It will fail, though, if the path contains spaces.

You can also use the following:

call :del_file %WPINSTDIR% a.dll
goto :eof
:del_file
del "%~1\%~2"
goto :eof

which should work even with paths containing spaces. The ~ in %~1 removes surrounding quotes.

This might do:

set current=%CD%
CD /d %WPINSTDIR%
DEL /s a.dll
CD /d %current%

EDIT
Edited to use CD /d and the "%CD%-trick".
