You can place restrictions on upload fields (= fields in which documents can be uploaded and saved). For example, applicant upload fields can be restricted to the standard PDF format. With this setting, you can limit the available upload options to ensure that a consistent file format is always used, thus eliminating the laborious task of converting files from one format to another.

Please note:

  • When uploading files, your Umantis solution performs an automatic check (in the background) to ensure that each file is valid. To set up a file format restriction for uploads, take note of the information provided in the following sections. A list of file formats available for restrictions is given below.
  • If an MP4 file has the MIME type quicktime, the upload is not prevented. In general, the MIME type should always match the respective file extension.

Restricting the file formats permitted for uploads

For file uploads, you can specify which file extensions / file formats will be accepted in the upload fields. This means that these fields are “restricted” to uploads of these file formats. A common use case is restricting document uploads to allow PDF files only. This is often used for job applications, for example. To achieve this, the administrator specifies in the global security settings which file formats are allowed when uploading files. Restrictions for individual upload fields can then be set up in configuration mode An error message informs the user if the file to be uploaded is not in one of the permitted formats.

Use case for useful restrictions on file formats

Example: Restricting an upload field in an application form to the PDF file format:

  • Modify the global settings for file extensions in the security settings. Select “Portable Document Format file” (PDF):

  • Click on and scroll down to “Error correction during entry”, where you will then select “check MIME type”:

  • If an applicant now attempts to upload a file in a non-permitted format, an error message will be displayed.
