最近MyEclipse8.5不知怎么了，一打开工作空间不让选择，直接默认为 C:\Documents and Settings\Administrator\Workspaces\MyEclipse 8.5，因为用着不方便，所以通过实践找到了修改默认空间的方法。
若希望在启动MyEclipse时就进入我们所设置的工作空间，有一种设置办法是通过修改如下配置文件来解决该问题：找到MyEclipse 8.5的安装位置，找到config.ini文件。
该目录为MyEclipse的安装根目录下configuration目录下的config.ini文件。使用EditPlus打开该文件。 文件内容如下

在第6行有如下内容： osgi.instance.area.default=@user.home/Workspaces/MyEclipse 8.5 将其修改为：
osgi.instance.area.default=G\:\\MyEclipse 8.5\\Workspaces
其中G\:\\MyEclipse 8.5\\Workspaces为期望的默认加载工作空间 保存文件，重启MyEclipse即可！
