Defining file extensions for Document Library documents

Issue

• Is it possible to define what file extensions are allowed to upload into Document Library?

Environment

• DXP 7.1+

Resolution

• This configuration is done through UI :

Control Panel -> System Settings -> Documents and Media -> SYSTEM SCOPE -> Service -> File Extensions sections

• Every file extension is defined with 'dot'[extension string] Some examples:
  

  .gif

  .jpg

  .odt

  .pdf

  .png

  .ppt

  .pptx

  .rtf

  .tiff

  .tgz

  .txt

  .vsd

  .xls

  .xlsx

  .xml

  .zip

  .jrxml

   
• You can save and export the configuration. It will be available in com.liferay.document.library.configuration.DLConfiguration.config

file with all options syntax. This way, you can apply this configuration to others environments.

• There are two additional file extensions configurations besides, for Web Content and Blogs:

Control Panel -> System Settings -> Web Content -> SYSTEM SCOPE -> File Uploads -> Allowed File Extensions sections

Control Panel -> System Settings -> Blogs -> SYSTEM SCOPE -> File Uploads -> Allowed Blogs Image File Extensions sections
