What is the FastNeuronDelta file extension?

FastNeuronDelta is the proprietary file format for deduplicated file backup chains.

A backup chain consists of one full backup and N incremental or differential backups (deltas) that follow and depend on it. The file name extensions are as follows:

.1.FastNeuronDelta files are full (compressed and optionally encrypted) file copies
.0.FastNeuronDelta files are increments or differentials of the above.

In order to restore a deduplicated backup file, you must have access to the latest full copy as well.
