The default size limit for uploading files into your Teaming site is 2 GB. You can change this limit by editing the applicationContext.xml file.
Change to the following directory:
Open the applicationContext.xml file in a text editor.
Search for FileUpload.
This brings you to a comment line followed by a JavaBean definition.
Copy the comment line and the complete Java bean definition to the clipboard of your text editor.
Open the applicationContext-ext.properties file, which is located in the same directory as the applicationContext.xml file.
Paste the block of lines you copied at the end of the applicationContext-ext.xml file.
Edit the maxUploadSize value as needed for your Teaming site.
You must specified the size in bytes.
Save and close the applicationContext-ext.xml file.
Close the applicationContext.xml file without saving it.
Stop and restart Teaming to put the new upload size limit into effect for your Teaming site.
