Added or deleted files should be handled without causing problems for the application. However, if an existing file is modified in place, there is a small risk for other types of exceptions that can't be properly handled. Therefore, never modify an existing data file; remove the old and create a new file with a new name instead.

Also, copying a large file into the data directory may take some time. Until the copying is complete, monitoring applications will see a half-written file, and are likely to generate errors when trying to read it. These errors should be handled automatically, and on a following scan when the file is complete, it will be added to the dataset. But the errors will show in the Carmenta Engine log, and will also fire a lot of unnecessary Runtime.StatusChanged events. Therefore it is recommended to first copy large data files into a temporary directory on the same disk, and then just move the files into the data directory.
