# FileGetMimeType

Gets the MIME type for the file path/file object you have specified.

## Method Signature

```
FileGetMimeType(file=[string], strict=[boolean])
```

### Arguments

| Argument | Type      | Required | Description                                                                                                                                        | Default |
| -------- | --------- | -------- | -------------------------------------------------------------------------------------------------------------------------------------------------- | ------- |
| `file`   | `string`  | `true`   | The file path or file object to get the MIME type for.                                                                                             |         |
| `strict` | `boolean` | `false`  | If true, throws an exception if the file does not exist or is empty. If false, returns "application/octet-stream" for non-existent or empty files. | `true`  |

## Examples

### Two PDFs and two text files with and without strict mode

Assume that you have a file named test.pdf in temp directory and test.txt in the same folder, and you want to check the MIME type. Here test.txt is a copy of test.pdf with extension renamed to txt.

```java
<bx:script>
	mimeTypes = "";
	mimeTypes = listAppend( mimeTypes, fileGetMimeType( expandPath( "/folder1/test.pdf" ) ) );
	mimeTypes = listAppend( mimeTypes, fileGetMimeType( expandPath( "/folder1/test.pdf" ), false ) );
	mimeTypes = listAppend( mimeTypes, fileGetMimeType( expandPath( "/folder1/test.txt" ) ) );
	mimeTypes = listAppend( mimeTypes, fileGetMimeType( expandPath( "/folder1/test.txt" ), false ) );
	writeOutput( mimeTypes );
</bx:script>

```

Result: application/pdf,application/pdf,text/plain,text/plain

### Additional Examples

```java
file = filegetmimetype( filepath / filename.EXT );
writeDump( file );

```
