DRM puts a 4mb limit restriction on loading a file from local system. It expects users to load larger files from the server. however it may not always be possible for us to get access to server. Here is a small tip to fix it.
1. create a shared folder on your local pc.
2. grant read/write access to the folder.
3. create an external connection in drm and point it to this folder, using the local pc IP address or the computer name.
