Good news.
If you connect the DVR to your computer with a regular USB Data cable, not a power cable, the DVR is recognized as a storage device.
You can download and download files, view all folders and files, format the card, tag it, defragment it, or perform a read/write speed test.
This is sometimes more convenient than using an application.
Write and read speeds are the same and equal to 12 MB/sec
If the card is 64 GB, it will take 1.5 hours to fully read it.
