Installation

------------

To install recoverjpeg, run



    ./configure

    make

    sudo make install



To use sort-pictures, you need to install:



  - exif: http://sourceforge.net/projects/libexif

  - ImageMagick: http://www.imagemagick.org/



Usage

-----

Look at the manual pages for recoverjpeg(1), recovermov(1) and

sort-pictures(1).



What to do if the medium is physically damaged?

Another option suggested by Florian Schmaus is to use the dedicated

[ddrescue](http://www.gnu.org/software/ddrescue/ddrescue.html) which may cope with

even more desperate situations where multiple passes are needed in order

to recover the physical medium content.



History

-------

recoverjpeg was written on 23 December 2004 after a *huge* mistake:

a disk containing pictures was repartitioned and a new operating

system was installed on top. recoverjpeg and sort-pictures ran on

this 80GB disk and rescued 19222 pictures (11GB):



  - 9538 pictures sorted by date (a few of them were corrupted in a

    way that no software can detect as they are valid JFIF files)

    and taken on 337 different days



  - 1310 JFIF files without date (some of them were correct pictures

    whose exif data had been corrupted)



  - 8301 JFIF files too small to be digital pictures (no error there,

    most of them were thumbnails of real pictures previously made

    by software such as gqview)



  - 71 invalid JFIF files



  - 4 pictures recorded at a date of 0000-00-00 (probably a bug

    in the camera used to take the pictures)



Of course, I had a backup of everything, but I cannot seem to remember

where I put it.



On January 2010, Jan Funke added the recovermov(1) program to the package

to recover lost movies.



On April 2012, Samuel Tardieu added the -d option to recoverjpeg(1) to

circumvent arbitrary limits set on the number of files per directory on

certain limited filesystems. Also, support of compilation with clang(1)

was added.



Portability

-----------



You need to ensure that the off_t type from the C library and the

lseek() function support offsets of at least the size of the device

you want to recover pictures from.
