检查文件状态并将其删除（Windows中映射的Linux驱动器）

I have written a small application to archive historical data from a set of weather station. My program does the following:

我写了一个小应用程序来存档来自一组气象站的历史数据。我的程序执行以下操作:

• Check if input file exists

检查输入文件是否存在

• Check if input file is open by another program (probably, the application sending data from the weather stations).

检查输入文件是否由另一个程序打开(可能是应用程序从气象站发送数据)。

• Append all the contents to an archive file.

将所有内容附加到存档文件。

• Delete the input file (will be created again next time there is new data from the weather stations).

删除输入文件(下次有气象站的新数据时将再次创建)。

The Java program is running on a Windows machine, and if accessing a local file everything runs smoothly (I can check whether the file exists and whether it is in use). But when we started using a Linux drive mapped onto the Windows machine, I started getting false negatives on the exists-check and false-positives on the in-use-check.

Java程序在Windows机器上运行,如果访问本地文件,一切运行顺畅(我可以检查文件是否存在以及是否正在使用)。但是,当我们开始使用映射到Windows机器上的Linux驱动器时,我开始对使用中检查中的存在检查和误报进行错误否定。

Any ideas on what I can do to make it work?

关于我能做些什么才能让它发挥作用的任何想法?

Here is my code:

这是我的代码:

File originalFile = new File (currentPath +  "\\" + line[1]);
if (originalFile.exists()) { 
    boolean fileIsNotLocked = originalFile.renameTo(originalFile);
    if (fileIsNotLocked) {

        /* WORK WITH THE FILE TO COPY ITS CONTENTS ETC */

        if(originalFile.delete())
            System.out.println("Successfully deleted file at = " + originalFile);
        else
            System.out.println("Could not delete file at = " + originalFile);
    }
}
