I am wondering if we can delete the file by opening it with FILE_FLAG_DELETE_ON_CLOSE, and immediately close it again. The semantics should be clear if we let the OS delete the file after the last handle on it is closed ? Until all handles are closed another process can still open it with FILE_SHARE_DELETE (according to docs), but not without the flag. This seems to be what we want. http://msdn.microsoft.com/library/default.asp?url=/library/en-us/fileio/ fs/createfile.asp If this fails (see the loop in dirmod.c) we could try to move it to the recycle bin with SHFileOperation with FO_DELETE. It seems the win unlink is not implemented correctly and we need to replace it. I don't feel easy with the ignore EACCES idea. Should I try to supply a patch along this line ? Andreas
