ext2read's Issues

Separate library from gui ?

Hi,
I think it would be a good thing if the library was separate from the gui so things can be clearer and easy to understand. I need access some files in an ext4 image without mounting in my project.
E.g an api would be good.

Finds one but not the other logical volume

Great project this, no other Windows app I know of can read LVM/ext4 drives. When I try it, ext2read opens volumes_fedora/root but fails to open volumes_fedora/home. There's no error message, it just doesn't show up. Here's the log. Both drives are ext4 on LVM2.

Problems reading directories on USB

While I can successfully read partitions of my internal drive, I have problems accessing my external drive (connected via USB). The format is ext4. All folders except for lost+found are displayed like files and therefore cannot be expanded. Viewing the properties lists them still as type Directory.

Building instructions

Can somebody please elaborate on the building environment?

I downloaded Qt 5.8.0 and used Qt Creator with Visual Studio 2015 compiler on Windows 10, but dirent.h was not found. Therefore, I suggest another compiler must be used. Which compiler works?

@mregmi Do you use MinGW or GCC (cross-compiling)? Or something else?
