Description
Silently send file(s) or a directory to the Windows Recycle bin instead of permanently deleting it.
Standard MS-DOS wildcard characters (*?) are permitted only in the file-name position.
The function return value is pushed on the stack. A non-zero value indicates an error.
Note: This code relies on the undocumented fact that the system plugin zero fills &X struct types
Usage
Section "Example" WriteINIStr "$TEMP\testfile.ext" foo bar baz ;We need something to delete !insertmacro SHFileOperation_Recycle "$temp\testf*e.ex?" $0 DetailPrint RecycleError=$0 ;0 = OK SectionEnd
