Explore a img backup file.

Hello

I have download from youtube an retropie backup and I can't use that because my setup is with a raspi drive,so the rom pads are not correctly I think and I want my own fine tuned gadget.

But maybe there are files the backup that I can.
It is a backup.img, I can't extract it or mount it.
Only win32disk imager accept the file for the setup.

So anyone suggestions?

Thanks for you're time

You can install ext2fsd which will install the drivers your Windows machine will need to recognise ext. You an then mount the image with an mounting tool such as Mount Image Pro or FTK Imager.

For those of the Mac persuasion that might also benefit from this post in the future, you guys are covered too.

This ability is invaluable in both Windows and Mac environments for dealing with updates and card migration, among many other things.

Use Linux Reader for Windows users
There you can view and extract files out of the images.

Hello

first off all thanks for the reactions.

i have write the image on a external 2tb drive, but both programs give me the error that they cant open the disk.
do i have using a micro sd?because i dont have them so big.

there must be a way to explore the files.

EDIT: Now i have hooked the usb hard drive on my pi and in berryboot i can see the structure but i cant login yet in winscp because it is only berryboot that was starting.
Also when i startup my Original pie setup and loging with winscp then i only see the structure from that setup and not the extra drive.
i must be in the root of the pi and then go external i think but how.

@BUZZ has the best solution, it just takes some execution. I recently was able to make it work like so:
(I'll provide the shortest answer I can first, with additional details about what didn't work if you care.)

Download and install Ext2Volume Manager drivers. These allow your Windows PC to read a mounted Linux EXT2/3 file system.
https://sourceforge.net/projects/ext2fsd/files/Ext2fsd/
Complete online (free) registration for the AccessData FTK Imager. I'm using an older version (3.4.3), they're up to 4.2 now. I assume 4.2 works, but I know 3.4.3 works.
https://accessdata.com/product-download/ftk-imager-version-4.2.0
Make sure you've installed and run the Ext2Volume Manager program. It doesn't have to have the GUI actually running, but you do have to authorize the drivers to run. If you've rebooted since installing it, and didn't choose to autorun on Windows startup, you may have to open the program again. If the rest of this doesn't work, it's probably because the drivers aren't installed/activated.
Open the Access Data FTK Imager program and under File, select Image Mounting.

5.) In the "Mount Image To Drive" window, select your RetroPie.img file. It can be stored locally on your PC, or accessed over the network (thank goodness.) It's actually fairly quick over the network.

Once it scans the .img file - !!!THIS IS IMPORTANT!!! - under the "Mount Method" drop down box choose "Block Device / Read Only".
Press the "Mount" button and the two partitions will be mounted as new drives, both readable. ASSUMING YOU INSTALLED THE Ext2Volume Manager drivers in step one.
Browse and copy the files you need to wherever you want.

Everything below this is just FYSA.

-There is an option to make the mounted files read/write. It does work, as long as you choose a temp location. However I'll be damned if I can figure out how to recombine the two mounted drives back into one bootable .img file once you've modified them. I'm sure there is a way, and I'm going to work on it. I'll update if I figure it out. At least now you have a way to extract copies of files (i.e. video snaps, images, ROMs, etc.)

-The alternative to Access Data FTK Imager is supposed to be "Mount Image Pro" (another forensics kit.) It installs, but consistently crashed for me when I tried to open a networked .img file. Additionally, it requires you to register as well, but you only get a 30 day trial evaluation once you do.
