Removing a project from P4 control
To remove a project from P4 control, right-click the project and choose Team>Unmanage. To verify that the project is no longer under P4 control, right-click the project and choose Team. The only option displayed for an unmanaged project is Share Project...
Although P4 is no longer configured as the SCM provider for the project, its files remain in the depot and in your workspace. If you have any project files open in changelists, they remain open in the changelist (and can be submitted). To put the project under P4 control again, proceed as described in Putting a project under P4 control . Be advised that, if you have made changes to the project after removing it from P4 control, your changes will be overwritten if you sync (retrieve) the project files using a different P4 client application (for example, P4V).
