Description
The specified file could not be opened. This may be due to incorrectly specifying the path or not having permission to access the data folder. If the file is being accessed by another ArcMap or ArcCatalog session, or another application, it may have a file lock placed on it.
Solution
Check that the file exists and you have correctly identified it. You may also need to check that you have the correct permission and that no other applications are already accessing it.
