    I can not thank you enough for taking the time to write this program. I have a Nokia 6790. Unfortunately some how my screen got cracked and it would barely light up. I know I had many pictures and videos I had taken with this phone that I didn't want to loose. I first tried to install the Nokia PC Suite: " Nokia_PC_Suite_eng_us_web.exe " Then I was having problems with Windows 8.1 USB drivers as many others was having here on the Microsoft forums. I was able however to use Nokia PC Suite to perform a complete backup successfully which created the *.nbu file archive. But I had no way of opening it up. Nokia PC Suite would only let be copy the backup back to my phone overwriting everything. I didn't want to do that. Now thanks to NbuExplorere, and installing the DBshell as mentioned in the readme.txt file I was able to view and extract everything sucessfully. Note: For those of you complaining about viruse's, adware etc.. This program has none of that. VirusTotal.com reports nothing. No threats. However when I ran a scan on the DBSHELL.EXE one false postive showed up from a company called "baidu"? Never heard of them. None the less, they reported that "DBSHELL.EXE" had: Win32.Trojan.WisdomEyes.16070401.9500.9644 IT IS A FALSE POSITIVE!! ( read what dbshell is all about ) the links are in the readme.txt file of nbuexplorer. Anyway thank you again so much for your work on this application. I'm now able to see videos and pictures of my beloved wife whom I lost to lung cancer , a damn tumor, in 2013. The pictures & videos were retrieved and saved because of this program "NbuEplorer" along with every single other file, contacts... etc...

    Works great. But must be installed carefully, to skip all crapware ;) Or install using ZIP file - find latest build in Releases files sourceforge.net/projects/nbuexplorer/files/Releases

    Very helpful app for restoring messages, calendar entries, contacts, images, etc. from an .nbu file created with Nokia PC Suite! Thank you very much! As others have pointed out: always use the program from the zip file in the latest release folder, not the exe version announced at the top. You do not even have to install anything – once extracted from the zip file, it runs standalone.
