+## Parsing File Tags
+
+The Textarea fieldtype supports the use of file tags in the format `{file:XX:field}` where `XX` is the file ID and `field` is any field associated with that file, such as `url`, `filename`, `title`, etc.
+
+When the content of a Textarea field is parsed for display, these tags will be replaced with the corresponding values from the file model.
+
+For example, if you have a file with ID `5`, and you want to insert its URL into the Textarea content, you would use the tag `{file:5:url}`. When the content is rendered, this tag will be replaced with the actual URL of the file.
+
+The supported fields for file tags include:
+- `url`: The absolute URL to the file.
+- `file_name`: The name of the file.
+- `title`: The title of the file.
+- `description`: The description of the file.
+- `file_size`: The size of the file in bytes.
+- `mime_type`: The MIME type of the file.
+- `location`: Where the photo was taken
+- `credits`: Photo credits
