推荐答案

如果文件由另一个进程以独占模式打开，则不能-Windows不会允许您.在这种情况下，最好的办法是等待其他进程关闭文件然后将其删除，或者使用

If the file is opened by another process in exclusive mode, you can't -- Windows won't let you. In that case, the best you can do is to either wait for the other process to close the file and then delete it, or have it be deleted at the next reboot by using MoveFileEx() with the flag MOVEFILE_DELAY_UNTIL_REBOOT and a destination location of NULL.

如果通过另一个进程非专有地打开了文件，则可以仅调用 DeleteFile() 通常(假设您有权这样做).该文件将在另一个进程打开时保留，但是一旦另一个进程关闭，它将被删除.

If the file is opened non-exclusively by another process, you can just call DeleteFile() normally (assuming you have permission to do so). The file will remain while the other process has it open, but it will be deleted as soon as the other process closes it.
