如题~!
File[] files = File.listRoots();
用这个可以得到系统盘符:如:c、d盘等
javax.swing.filechooser.FileSystemView; 这个类也看了,好像还是不可以哦。
如何得到呀 大家帮忙看下哦~!!谢谢啦就像这个样子的系统目录,说白了就是按Windows键+E建 出来的左边的那个目录。- Desktop
+ My Documents
- My Computer(展开中)
+ WinXp(C:)
+ Programs(D:)
+ Backup(E:)
+ DVD-RAM Drive(F:)
+ Control panel
+ Shared Documents
+ Roger's Documents
+ My Network Places
+ Recycle Bin

请问???应该是什么,Desktop ?不是,我试过了,这样不行,那么应该是什么呢,我不知道了。
