NAME

adfinfo - show low-level information (filesystem metadata) about the Amiga Disk File (ADF) devices and about the volumes, the directories and the files stored inside.

SYNOPSIS

adfinfo <image_adf> [vol] [path]

DESCRIPTION

adfinfo is a simple utility allowing to display metadata of ADF images. This includes low-level information about:

devices: type, geometry, volume list
volumes: type, Amiga filesystem type (OFS/FFS), free blocks, block information (boot block, root block)
directories: directory block, hashtable
files: file header block, extension blocks, data blocks

It can be useful for exploring or debugging low-level device structure and filesystem information within ADFs.

Also, anyone interested in a low-level structure of filesystems or retro- computing can explore a bit solutions made for Commodore Amiga computers a few decades ago. Enjoy!

EXAMPLES

adfinfo mydisk.adf

shows metadata of the device (ADF image mydisk.adf) and its volumes

adfinfo mydisk.adf s

shows metadata of the directory s (on volume 0 of mydisk.adf)

adfinfo mydisk.adf s/startup-sequence

shows metadata of the file s/startup-sequence (on volume 0 of mydisk.adf)
