Why is it worth using your software if there are many analogues?
512byte_developer

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?
512byte_developer

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?
512byte_developer

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?
512byte_developer

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.

Andrey Fedorov
How does the software extract the photo if the file is corrupted?
512byte_developer

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.

Andrey Fedorov
Why does the software save the preview?
512byte_developer

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 doesn’t the software support DNG format?
512byte_developer

The three most popular formats (CR2, ARW, NEF) occupy more than 75% of the market. We decided to support the most popular Raw photo formats.

What are .lrv files? How to open them?
512byte_developer

Lrv files are video previews that your camera saves along with full-size video .Lrv files have less resolution and less size.
The file can be played by any video player that supports mp4 format. If the default program is not installed for this extension, you can select it through the "open with" menu.

Why is the start LBA value and cluster size value are so important? How does this affect the result?
512byte_developer

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 soft@512byte.ua and we will help you set the parameters.

Does softwareonly work with GoPro Hero7 cameras?
512byte_developer

Our software has been tested so far only on this camera model. We plan to add support for more models, and we are making appropriate tests for these.
If you encounter a problem that you cannot solve, we are ready to supplement our software for your case or create a separate software for this case.

Why does the demo version save files only less than 5 MB?
512byte_developer

We decided that when setting the limit to 5mb, a sufficient number of video previews are saved to demonstrate the operation of the software.

Hi Andrey....I'm trying to test the DVR soft but it just show me as result a list of files. No video show to verify is can recover well the data......my dvr is a ALHUA DHFS 4.1
512byte_developer

In the demo version, result is a list of the date and time a video can be recovered.

We specifically made this restriction. If we recover the video in the demo version, the user, who sets the selected image fragments to the software input, can recover the required video.

You can send me any fragment of the image, I will send you a video.

Video is available only in the full version.

All contacts are deleted from a device accidentally. The tables of contacts2.db file are empty. What should I do?
512byte_developer

Open Image file of internal flesh memory of device where contacts2.db file was placed first. Then open the folder with extracted contacts2.db file. The found sqlite records will be displayed in the software: “Contacts” partition contain the records of raw_contacts table that are linked by key with the phone number of phone_lookup table.

I need to recover sqlite records from a custom program but there are just some icons of common data in the interface of program (such as contacts, calls, SMS Messages, etc). Is there any sense to use your software?
512byte_developer

The records can be placed in partition “Other Tables”.

Vadim Tkachuk
What versions of Android OS are supported?
512byte_developer

The software isn’t linked to versions of Android or to any file system for mobile devices or PC. The software recovers sqlite-records from a file system (the structure of sqlite data base is no less 3.0.0 version)
