Increase maximum size of List Template

If you try to save a list as a list template, you may see the following error due to the list being too large: The list is too large to save as a template. The size of a template cannot exceed 10485760 bytes.

You can increase the maximum size of a list / site template by running the following command (note that 500mb is the largest you can go):

stsadm -o setproperty -propertyname max-template-document-size -propertyvalue 50000000
