使用Java的JNA获取窗口正在访问的文件的文件路径

Question

I am using JNA with Java to find some properties about open windows on a Windows machine desktop. I am trying to find a way to get the file being accessed by an arbitrary windowed application. For instance, say I get information regarding the window of an open pdf document in adobe. I want to be able to get the filepath of the pdf document displayed in the window.

I know about the GetWindowModuleFileName() method, however this gets you the filepath of the executable of the application, ie 'javaw.exe'. If you have 'my.pdf' open in adobe, I'd like to get the filepath of this document, ie 'C:\\...\\my.pdf'.

I've done some searching around (on this site and others) and haven't found anything yet on this in particular.

thank you for your time, -Kevin

Answer 1

If you know the process ID, you can get the list of all files currently opened by the process using Handle utility. However, it depends if adobe reader continues to keep the file open or closes it after reading it completely.
