+An input of `/logs/2022` will only replicate data contained within the specified folder, ignoring the `/files` and `/logs/2021` folders. Leaving this field blank will replicate all applicable files in the remote server's designated entry point. You may choose to enter a [regular expression](https://docs.oracle.com/javase/8/docs/api/java/util/regex/Pattern.html) to specify a naming pattern for the files to be replicated. Consider the following example:
 
 ```
 log-([0-9]{4})([0-9]{2})([0-9]{2})
 ```
 
 This pattern will filter for files that match the format `log-YYYYMMDD`, where `YYYY`, `MM`, and `DD` represented four-digit, two-digit, and two-digit numbers, respectively. For example, `log-20230713`. Leaving this field blank will replicate all files not filtered by the previous two fields.
 
-4. **Most Recent File**: Toggle this option if you only want to sync the most recent file located in the folder path. This may be useful when dealing with data sources that generate frequent updates, such as log files or real-time data feeds. Set to False by default.
+14. Click **Set up source** to complete setup. A test will run to verify the configuration.

+#### File-specific Configuration
+
+Depending on your **File Type** selection, you will be presented with a few configuration options specific to that file type. 
+
+For JSONL, Parquet, and Document File Type formats, you can specify the **Glob** pattern used to specify which files should be selected from the file system. If your provided Folder Path already ends in a slash, you need to add that double slash to the glob where appropriate.
+
+For example, assuming your folder path is not set in the connector configuration and your files are located in the root folder, use a glob pattern like `//my_prefix_*.csv` to specify your file. If your files are in a folder, include the folder in your glob pattern, like `//my_folder/my_prefix_*.csv`.
