I also cannot rename files and get the following error:
If I try to re-import the project from TFS I get this error:Operation Rename failed: All specified files must reside in the same workspace. Workspace XXXXXX contains C:\Users\FirstNameLastName\Desktop\ProjectFolder\Content\Operations\system-guides\HRC User Guide
Can't find Project.flprj - C:\Users\FirstNameLastName\Desktop\ProjectFolder\CRL2016
