Grub2 File Manager – List devices and files

Grub2 File Manager helps you browse the list of devices and files, it also supports reading text files, opening ISO files and partition images.

Grub2 File Manager

By using Grub2 File Manager, you can browse files and folders on all partitions on your computer. In addition to reading text files, it also supports booting from the files it supports.

For the files it supports, you can place these files anywhere on your computer and then access them for processing. You can put your ISO file (such as Ubuntu, Linux Mint…) on your hard drive and boot it from AIO Boot on USB. To quickly list files, you should copy them to the /AIO/Files directory, then press the j key from the Grub2 menu to quickly list these files. However, I recommend that you Integrate the files through AIOCreator.exe, unless you can not run it, or you are using Linux.

From the Grub2 main menu, press d for quick access to the File Manager menu.


You can use the ls command to list devices and files. Press c to enter commands.

List the device list, including hard disk, floppy disk, CD/DVD…

ls -l

List the folders and files on the root device:

ls -l /
ls -l /AIO
ls -l /EFI

List folders and files on another device (eg hd1,msdos1):

ls -l (hd1,msdos1)/
ls -l (hd1,msdos1)/AIO
ls -l (hd1,msdos1)/EFI

Use the cat command to read the text file:

cat --dos /autorun.inf
cat (hd1,msdos1)/myfile.txt
cat /etc/fstab

Use the loopback command for filesystem files. For example, the partition image file (PartIMG) and ISO (iso9660).

loopback loop0 /AIO/Files/PartIMG/PartIMG_ROOT.img
ls -l (loop0)/
loopback -d loop0
loopback loop1 /ubuntu.iso
ls -l (loop1)/
loopback -d loop1

The Grub2 File Manager also uses the cat and loopback commands to open the files.
