# File Upload

The file upload question generates a question with a [file upload](/form-management/form-designer/answers/answer-types/file-upload.md) answer type to let you respondents upload a file. You can add as many file upload answers as you wish in your questions or survey.

Once uploaded you may use the [file manager](/form-management/reports/files.md) to download the files or you may also download the respondent files on each [individual respondent report](/form-management/respondents-management/respondent-details.md) page. 

## 🔅 File upload properties

You may manage all file upload properties from the [answer properties](/form-management/form-designer/answers/answer-types/file-upload.md) of your file upload answer.

* **`Max. file upload number`** maximum number of files that the respondent can upload.
* **`Max. file size`** maximum size allowed file for the file.
* **`File type filter`**restricts the type of files that the respondent can upload.
* **`Save a copy to Google Drive`**saves the uploaded file to one of your Google Driver folder provided that you have linked a [Google Service account](/installation-setup/system-settings/google/service-account.md) to your [ngSurvey account](/personal-account.md).

{% hint style="info" %}
The file type filter uses mime type specifications to filter out the content. You may check following [list of mime types](https://developer.mozilla.org/en-US/docs/Web/HTTP/Basics_of_HTTP/MIME_types/Common_types) that you can use to filter out content. If you would like to filter out multiple types of content you can do so by separating each mime type by a **;** char
