| pathPrefix | string | The path prefix. Must not be null. Must be a valid path and may ends with a prefix for the file name itself. |
| fileSuffix | string | Suffix for the file name. Must not be null. Typically an extension (like ".txt"). |
| time | System.DateTime | The time that will be used to create the file name. It should be an UTC time. |
| content | byte | The bytes to write. Can be null or empty if the file must only be created. |
| withUTF8Bom | bool | True to write the UTF8 Byte Order Mask (the preamble). |
| maxTryBeforeGuid | int | Maximum value for short hexa uniquifier before using a base 64 guid suffix. Must between 0 and 15 (included). |
