Electronic filing is the crux of the ACE system. It allows registered attorneys to file pleadings and other documents electronically with the court from the convenience of their home or office. This provides for reduced cost and labor spent producing and filing a pleading manually with the court.

There are several changes in electronic filing with ACE 2.0. The first major change is that all cases are deemed electronic and attorneys can file electronically to any case in District Court. This is due to the recent abolishment of the Motion Packet Rule. Therefore, it is no longer necessary to motion the court to allow electronic filing in a case. In addition, attorneys are no longer restricted to filing only to cases which appear on a "drop-down" list at the initial filing menu. Redesigned screens allow an attorney to simply type in the number of the case he wants to file to and submit the documents.
