推荐答案

高级别，听起来用于生成文件的代码没有关闭文件，因此生成文件的方式是将文件保持打开状态。没有看到你的代码，但建议学习如何处理用于生成
文件的对象，这并不多说。

High level, it sounds like the code used to generate the file has not closed the file so how you generated the file is leaving it open. Not much to say without seeing your code but would suggest learning how to dispose of the object(s) used to generate the file.
