How to change the maxlength to allow more Library File extensions

  • Updated

When attempting to add more than 255 characters to the library file extensions field, the system throws the following error: The file type has not been added. Please see administrator.


If you need to add more file extensions to the library, please use the following steps.


  1. Make a backup copy of workarea\library.aspx
  2. Edit the workarea\library.aspx file
  3. Look for the following line
    maxlength="255" value="" runat="server"/>
  4. Change the maxlength property from 255 to 1024
    maxlength="1024" value="" runat="server"/>
  5. Save the file and you should now be able to add in more library extensions.

Please see the following KB for other issues related to adding library file types.
