Could not read disk MBR error about sharpext4 HOT 9 CLOSED

You need to convert the virtual machine (.vhdx) format to the raw disk format.

from sharpext4.

Can you give an idea on how I can do this?

As far as I know, the file header format is different.

Yep, it doesn't seem to work for me. Actually, I can read the paths of the files with DiscUtils, but I need to export these files. Any idea how it could be?

If you can use diskutils, you should be able export those files without any issue. Diskutils only provides read permission only from the disk image, but not write.

SharpExt4 allows you to write a file to the disk image.

I am reading with this code. If I make any changes to this code, I can export it.

 var disk = new DiscUtils.Vhdx.Disk(secilen.Text, System.IO.FileAccess.Read);
                    DiscUtils.FileSystems.SetupHelper.SetupFileSystems();
                    var manager = new VolumeManager(disk);
                    var logicalVolumes = manager.GetLogicalVolumes();
                    foreach (var volume in logicalVolumes)
                    {
                        var fsInfos = FileSystemManager.DetectFileSystems(volume);

                        foreach (var fsInfo in fsInfos)
                        {
                            var fs = fsInfo.Open(volume);

                            string[] array2 = fs.GetFiles(fs.Root.Name, "*.*", SearchOption.AllDirectories);
                            foreach (string name in array2)
                            {
                                listbox.Items.Add(name);
                            }
                        }
                    }

listbox.Items.Add(name)
//Open file and read the content from the name
...

I don't think it's possible with something like this, but I tried it anyway.

string dd = listbox.SelectedItem.ToString();
FileStream fs = File.Open(dd,FileMode.Open);

You can't just use File.Open(dd,FileMode.Open). That is the.net native way. You need use diskutils API to open the file. Check diskutils file open API.
