How to change the number of workspace history in Eclipse

Sometimes, we are currently working in multiple workspaces, or we want to keep some old workspaces in the Eclipse workspace list.
By default, Eclipse can only keeps track up 5 workspaces.
So there could be problem when we want to open previous workspaces.

To resolve this problem, we can increase the number of workspaces history in Eclipse.


Steps:
1. Start Eclipse
2. Window > Preferences > General > Startup and Shtudown > Workspaces

3. increase the number in the red highlighted box to desired number, eg, 10.
4. remove unwanted workspace (optional).
5. click OK
6. now the workspace history can show more than 5 workspaces.

Done!!
