Video File Backup

Good day! I have an Axon server I have been trying to transfer the video files off of to make a backup of the files we are using.

In using the CMA, I've used drop and drag, copy and paste, all sorts of ways to transfer the files off. Every time I try something, it crashes the CMA.

I've tried this with a CMA on Windows 7, and the CMA on the Axon itself. No Change.

Does anyone know any other way? Please let me know. Thanks and take care!
