问题描述：
今天碰到鬼了，上网用的好好的，下午吃完饭就打不开了！！！！
其中我有2个工作空间分别是
D\:\\Workspaces\\MyEclipse 6.5\\sitech和D\:\\Workspaces\\MyEclipse 6.5
我上班用的是D\:\\Workspaces\\MyEclipse 6.5\\sitech这个工作空间，在打开无果的情况下 我进入第二个工作空间 居然可以进去，就是sitech 的这个进不去。
后来在网上查找资料 指出 有2个文件需要改动：
1、D:\MyEclipse 6.5\eclipse\configuration\.settings org.eclipse.ui.ide.prefs 文件
2、D:\MyEclipse 6.5\eclipse\configuration config.ini文件
D:\MyEclipse 6.5\eclipse\configuration\.settings org.eclipse.ui.ide.prefs 文件

D:\MyEclipse 6.5\eclipse\configuration config.ini文件
# Eclipse runtime configuration file# This file contains a number of key/value pairs that are merged into the # System properties on system startup. The values control the way the # runtime is structured and runs.# Note: Only platform:/base/ and file: URLs are supported. In general the # URLs given may include a version number (e.g., .../location_1.2.3). # If a version is not specified, the system binds# to the location which matches exactly or to the versioned location with the# latest version number. If a version number is given then only exact matches# are considered.# The URL for the runtime entry point. The default value is# platform:/base/plugins/org.eclipse.osgi #osgi.framework = platform:/base/plugins/org.eclipse.osgi# The classpath for the framework found at the osgi.framework location. This # comma-separated list contains either URLs or simple element names. Simple# names are assumed to be relative to the framework's install directory. # Typically this value need not be set as it is initialized by the framework itself.# Version match searching is not done for URLs listed here.#osgi.frameworkClassPath =# The comma-separated list of locations to search for the splash screen file (splash.bmp).# For each list element a subdirectory structure based on the pattern nl/<locale> is searched.# The system binds to the first matching file.

以上我没有任何修改完全正确的，根本就不需要网上说的那样改这改那的。
当然这只是我遇到问题的出来结果的经验告诉我的。
我的解决办法只是：选择空间的时候别马上点击下一步，要你选择工作目录的时候 有个seting--->下面有2个选择项 , 勾上就行!!!---------------------
这是MyEclipse8.5 的：
osgi.instance.area.default=@user.home/Workspaces/MyEclipse 8.5
这是MyEclipse6.5 的：
osgi.instance.area.default=@user.home/workspace
下面是我改后注释掉的：
#osgi.instance.area.default=D\:\\Workspaces\\MyEclipse 6.5\\sitech
更改工作空间
将其修改为：
osgi.instance.area.default=E\:\\Workspaces\\MyEclipse
其中E:\Workspaces\MyEclipse为期望的默认加载工作空间
但在ini文件需要写成E\:\\Workspaces\\MyEclipse
保存重启！over
下面还看到这种配法，file\我没遇到过，只是看到了，如果这样也可以的话，请告诉我。
#osgi.instance.area.default=@user.home/Workspaces/MyEclipse 8.5
osgi.instance.area.default=file\:/D:/workspace
