这是我关于堆栈溢出的第一篇文章。我在笔式驱动器上使用 Server2go 和 Portable Firefox。Server2go 中有一个名为 pms_config.ini 的配置文件。有一行允许您指定要使用的浏览器的路径。无论如何要获取USB的驱动器号，以便我可以将它动态包含在配置文件中？
[Browser]
;--- The browser that is started after server start (possible values: IEXPLORER, FIREFOX, PORTABLEFIREFOX, MOZILLA, DEFAULT, EXTERNAL)
;--- Please take a look at the www.server2go-web.de/wiki pages for a documentation how to use PORTABLEFIREFOX!!!!!!!!
BrowserType=PORTABLEFIREFOX
;--- Browser command options like -k (NOT IN USE AT THE MOMENT)
BrowserCommandOptions=
;--- Path to an external browser that is used instead the browser above
BrowserPath=G:\FirefoxPortable\FirefoxPortable.exe
;--- Specify caption text of Work Offline dialog box. You can use mor than one captions (seperated with ;)
;--- The captions for german, english, french, dutch and spanish are build in by default
WorkOfflineTitle=
;--- The size of the started browser. Can be a pixel dimension (1024x768) or the values MAXIMIZE and KIOSK (Internet Explorer only)
BrowserSize=
无论如何我可以使驱动器号由环境变量识别吗？
提前谢谢你的帮助 ：）。
