Situation: There is a fixed list of file extensions within GTC which defines that certain file types must not be uploaded. The system administrator has no possibility to modify this list due to security aspects.
Solution: In dialogue "Administration / System settings" the system administrator can configure which file types may and which file types must not be uploaded. For this purpose either a list of "Allowed file extensions" or a list of "Not allowed file extensions" can be defined If the list of allowed file extensions is configured, only files with a file extension included in the list may be uploaded. If the list of not allowed file extensions is configured, only files with a file extension which is not included in the list may be uploaded. It is not sensible to define both lists. In this case the list of allowed file extensions is the leading one. In each case the list is specified as a sequence of file extensions without the dot separated by a comma, semicolon or blank. Initially these settings are filled with file extensions not allowed in GTC. |
