# Options tab
In the **Options** tab, you can define properties for the file output.
| Option | Description |
| ----------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Compression** | Specify the codec to use to compress the Parquet Output file:
No compression is used (default).
Using Google's Snappy compression library, writes the data blocks that are followed by the 4-byte, big-endian CRC32 checksum of the uncompressed data in each block.
Uses a compression format that is based on the Deflate algorithm.
|
| **Version** | Specify the version of Parquet you want to use:
|
| **Row group size (MB)** | Specify the group size for the rows. The default value is 0. |
| **Data page size (KB)** | Specify the page size for the data. The default value is 0. |
| **Dictionary encoding** | Specifies the dictionary encoding, which builds a dictionary of values encountered in a column. The dictionary page is written first, before the data pages of the column. Note that if the dictionary grows larger than the **Page size**, whether in size or number of distinct values, then the encoding method will revert to the plain encoding type. |
| **Page size (KB)** | Specify the page size when using dictionary encoding. The default value is 1024. |
| **Extension** | Select the extension for your output file. The default value is parquet. |
| **Include date in file name** | Adds the system date to the filename with format `yyyyMMdd` (`20181231` for example). |
| **Include time in file name** | Adds the system time to the filename with format `HHmmss` (`235959` for example). |
| **Specify date time format** | Specify the date time format using the dropdown list. |
