Jpegdump - An Overview
I have written a small tool named jpegdump. One of its function
is to make an binary image copy of a memory card an extract all
included jpeg files, even if the files have been deleted (but
The current version jpegdump version 1.18
(less than 100 KB).
But, please, read the attached documentation, before using the
software. This file contains only some overall hints.
The tool is freeware and may be used (at own risk) without any
annotations. If you recover some accidently deleted picture, which
are valuable for you, I would like to hear from you and part your joys.
You can send me a mail to
firstname.lastname@example.org (Kurt Stege).
If you have problems with the software, or found bugs, or have good
ideas, please fell free to contact me.
Jpegdump - Some Hints
Recovering jpeg files
The most useful purpose of jpegdump is to recover deleted
jpeg files from memory cards for digital still cameras.
You need a windows system (NT, 2000 or XP preferred for
95, 98 or ME), a memory card with deleted files and a memory
card reader for this card. Most new digital still cameras
have an built-in card reader and can be used for this purpose.
If you are using an old Windows (95, 98 or ME), you need another
tool for copying the memory card onto the harddisc. I know about
a shareware software called winimage, see www.winimage.com.
How to recover the images
Read the manual in the zip-file near the executable.
What to do before loosing the images
You can rise the chances of recovering deleted images
in an accident by using a simple stratgy.
And jpegdump cannot recover fragmented jpeg files. So try
not to fragment the file system on your memory card.
You can do this best, when you delete all files on the
memory card after transmitting them to the PC. Don't delete
any single files on the memory card. If you want to delete
a single image after taking the photo, do it immediately.
The last stored picture may be deleted without much risk
of fragmentation. Deleting any other image will result in
a fragmentation of the free memory in the card, so don't
do that, if you want to be prepared for the case of an accident.
What to do after loosing the images
Keep calm, don't store any data on the memory card, until
you have used jpegdump (or an other recovering tool) and
got the images back. Even, if you have formatted the memory
card, you have good chances to recover the lost images.
Jpegdump - When it does not work
If you don't have success with jpegdump, you may try
other recovering tools.
You should look out for the professional tool
from LC Technology. This software has a graphical user interface, and,
most important, it recovers not only jpeg files but knows a whole bunch of
other file types.
