Where can I change the default workspace in Eclipse?
Open a command prompt. Change to the eclipse home directory and type "eclipse -clean" e.g. C:/eclipse>eclipse -clean
This will ask for the workspace selection. It will also force to set it as the default workspace.
Then, go to eclipsehome-->configuration-->settings folder.
open org.eclipse.ui.de.prefs in a notepad.
set this property to true from false.
SHOW_WORKSPACE_SELECTION_DIALOG=true
You will be asked for a workspace selection everytime.
On Ubuntu I went to
~/.eclipse/org.eclipse.platform_4.3.0_1473617060_linux_gtk_x86_64/configuration/config.ini
and added this line at the bottom
osgi.instance.area.default=@user.home/workspace
and changed workspace to the dir path from my home to where I put my workspace.
I combined @Frank answer with @Ronan Quillevere's comment
If you mean "change workspace" go to File -> Switch Workspace
