- A feature of the software is the ability to recovery not overwritten video frames from previous recording cycles on HDD
What is “Version 2 (Beta)”?
It is an alternative algorithm, whose advantage in joining more frames, was developed for the CPR-1602E1-TS DVR; the ability of working with other DVRs with WFS 0.4 is in the process of testing.

In addition to simply backing up at a specified interval. Our software changes the file extension and its header. Thus masking the file from ransomware, that scans the disk for files of a certain type (for example, documents or photos).
What happens if the ransomware encrypts all the files on the disk?
Then the backup will be damaged.
The “Failed to back up some files” window appeared. What does this mean? What will happen with listed files?
This means that these files are open in another program, so copying is not possible. During the next backup, the software will try to copy them again.
Why should I use this software if there are many online converters?
Our software is aimed at mass photo processing. Recovering more than a thousand files at the same time is not a problem, which cannot be said about online services. Our software will also check recovered JPG photos using the Huffman method and save only intact files.
How does the software extract the photo if the file is corrupted?
In most cases, the camera saves the Raw photo, Jpg preview and full-size Jpg photo separately. If any part of the Raw part or the header of the entire file is corrupted, the Jpg photo can still remain untouched. Our software extracts the Jpg and then checks it, keeping only intact photos. This distinguishes our software from the rest.
Why does the software save the preview?
They may come in handy during forensic investigations, as they may differ from a full-size photo. Also, if your camera does not support the function of recording a full-size Jpg photo together with Raw, the preview may be the only one that can be recovered if the Raw is corrupted.

Why is the start LBA value and cluster size value are so important? How does this affect the result?
Due to the nature of the file system, it is very important to start reading data from a specific sector to match clustering. Our software needs to find beginning of files, which is specified by the "start" field, and also move around the source by the size of the cluster. If you have problems with these values, contact us by e-mail firstname.lastname@example.org and we will help you set the parameters.
Does softwareonly work with GoPro Hero7 cameras?
