Multifile feature connection datasets have a file property that defines the dataset type and its format.
The following are some examples of when you should update your field information:
- To verify the correct file type was selected (delimited, shapefile, ORC, parquet)
 - To modify the quote character
 - To modify the encoding
 
Field properties details
Every data type includes a file format type: delimited, shapefile, ORC, or parquet.
Delimited files have additional properties that are not supported for shapefile, ORC, and parquet. The additional properties include the following:
- File extension—The extensions of the delimited file, for example, .csv. This property is not editable.
 - Field delimiter—The delimiter used to split fields. This property is editable.
 - Record terminator—The character used to split lines. This property is editable.
 - Quote character—The character used for quotes within a string. This property is editable.
 - Escape character—The character used to escape quotes. This property is editable.
 - Has header row—If the delimited file has a header row. This property is editable.
 - Encoding—The type of encoding. The default is UTF-8. This property is editable.
 
Changing the file properties for the multifile feature connection dataset does not modify your source datasets.
