Comentários
This enumeration is used by the connection manager for validation purposes. For example, if the connection is being used to delete a file, and the connection is pointing to a folder, it fails validation. In addition, this enumerator indicates to the connection manager whether ambiguous names are files or folders. For example, "C:\ABC" could be the name of a new folder, or it could be a new file in the C:\ directory. This enumeration indicates if it is a file or folder.
Exemplos
The following code example creates a package and adds a FILE ConnectionManager. The DTSFileConnectionUsageType enumeration describes the FileUsageType property as being an existing file by specifying the FileExists value.
