DoesPackageExist FAILED: '/Content/MAP_QTYB>>>>>>> ' is not a standard unreal filename or a long path name. Reason: Name may not contain the following characters: '> '

Hello everyone,

When I trying to cooking my game it fails. And Output Log is:

UATHelper: Packaging (Windows (64-bit)): LogInit: Display: LogPackageName: Error: DoesPackageExist: DoesPackageExist FAILED: '/Content/MAP_QTYB>>>>>>> ’ is not a standard unreal filename or a long path name. Reason: Name may not contain the following characters: '> ’

And there is no MAP_QTYB>>>>>>> in Content .

Any help appreciated!
