Optional: Configuring Multiple File Upload 
The Knowledge Management (KM) platform provides you with the option of uploading multiple files to a KM folder and applying certain properties to all of them in a single iteration. This option is enabled by default. Nevertheless, you can still work through some configuration steps to optimize the use of the multiple file upload.
Prerequisites
To use the multiple file upload feature you must have Java Runtime Environment (JRE) 1.6 Update 10 or higher installed with Enable the Next Generation Java Plug-in option activated.
Procedure
In the portal, navigate to 
System Administration 
System Configuration Knowledge Management Content Management 
.
1. Configure the value of the maximum allowed property of the multiple file upload
You can optionally configure the maximum allowed number of files per upload according to your requirements.
Choose
Content Management Utilities Multiple Files Upload Choose Edit and specify the required value for the Maximum number of files for upload property. The default value is 20.
2. Configure the file-specific and the common properties for the list of the selected files
You can optionally configure which properties are common for all of the files selected for upload and which properties are file-specific. For the multiple file upload, the type of the property (whether a property is file-specific or common for all of the selected files) depends on the current property structure of the current collection. If a property is directly included in the structure, it is considered file-specific. If a property is part of a property group (for example, all_groups group) and not directly included in the structure, it is considered common for all of the files selected for upload. For more information about modifying file-specific and common properties for a selection, see: Uploading Multiple Files to KM Folders
By default, only the Name and the Description properties are file-specific, whereas the rest of the properties are common. To change the default configuration, you need to either modify the default property structure, or assign another property structure to the multiple_upload command.
To change the default property structure of the current collection, proceed as follows:
Choose
Global Services Property Structures Property Structure Default Filter for the DefaultPropertiesStructure property structure, and open the structure for editing
Edit the Structure items parameter according to your requirements.
For more information about modifying a property structure, see Property Structures.
To assign another property structure to the multiple_upload command, proceed as follows:
Choose
User Interface Commands UI Commands .Filter for the multiple_upload command, and open the command for editing.
In the Parameters property input field, enter PropertyStructure=<structure_name>, where <structure_name> is the name of the property structure you want to assign to the multiple_upload command.
