 | OPTION 2: wildcard<br>- wildcardFileName | The file name with wildcard characters under the given folderPath/wildcardFolderPath to filter source files. <br>Allowed wildcards are: `*` (matches zero or more characters) and `?` (matches zero or single character); use `^` to escape if your actual file name has wildcard or this escape char inside.  See more examples in [Folder and file filter examples](#folder-and-file-filter-examples). | Yes |
 | OPTION 3: a list of files<br>- fileListPath | Indicates to copy a given file set. Point to a text file that includes a list of files you want to copy, one file per line, which is the relative path to the path configured in the dataset.<br/>When using this option, don't specify file name in dataset. See more examples in [File list examples](#file-list-examples). |No |
 | ***Additional settings:*** |  | |
-| recursive | Indicates whether the data is read recursively from the subfolders or only from the specified folder. Note that when recursive is set to true and the sink is a file-based store, an empty folder or subfolder isn't copied or created at the sink. <br>Allowed values are **true** (default) and **false**.<br>This property doesn't apply when you configure `fileListPath`. |No |
-| deleteFilesAfterCompletion | Indicates whether the binary files will be deleted from source store after successfully moving to the destination store. The file deletion is per file, so when copy activity fails, you'll see some files have already been copied to the destination and deleted from source, while others are still remaining on source store. <br/>This property is only valid in binary files copy scenario. The default value: false. |No |
-| modifiedDatetimeStart    | Files filter based on the attribute: Last Modified. <br>The files will be selected if their last modified time is greater than or equal to `modifiedDatetimeStart` and less than `modifiedDatetimeEnd`. The time is applied to UTC time zone in the format of "2018-12-01T05:00:00Z". <br> The properties can be NULL, which means no file attribute filter will be applied to the dataset.  When `modifiedDatetimeStart` has datetime value but `modifiedDatetimeEnd` is NULL, it means the files whose last modified attribute is greater than or equal with the datetime value will be selected.
