The indicated property's value resolved to a folder which appears to point to the root of a drive or network share, is a well-known folder such as My Documents, is the root project folder, or is a parent of a special folder or the project folder. If used, this would cause all files and folders in that location to be erased which is probably not what you want.

Set the property's path to a different location that is safe to erase without warning (i.e. a subfolder under the root project folder) or reset it to the default value which will result in a safe path. If your project file is stored in one of the folders noted above, move the project file and its related files to a safe location such as a sub-folder under My Documents or a sub-folder of the Visual Studio project folder to which it relates. See the help topic for the indicated property for more information.
