You can create a list of file names that cannot be uploaded by users in FileCloud 19.1 and later.

For security reasons you may want to create a set of rules for the working environment where many users have access to a central resource, such as files and folders in FileCloud Server.

  •  You can create a list of restricted file names that will stop a file from being uploaded if it contains the name. 

To understand how to create a list of file names, use the examples below.

(warning) If you leave an empty space in your list:

  • In the User Portal, all files will be blocked from being uploaded.
  • In the Sync client, it will ignore checking for restricted names.


(warning) If you add an extension to the file name, then only the combination of name + extension will be restricted.

(lightbulb)  To manage file extensions ONLY, you can either create a list of file extensions to restrict, or create a list of file extensions to allow.  Manage File Extensions
