    Just done some test using the 1.4.1 portable version and with a fresh 1.4.1 installation.

    With the settings you provided me, my compressed image keeps all the EXIF information in the right way.
    Can you provide me more details like:
    - Original folder path
    - Compression folder path
    - Which boxes are checked in the "Tools -> Settings -> Compression" tab along with "Keep EXIF info..."

    Did you try to compress other pictures taken with the same camera with the same options and check if EXIF is correctly copied?

    hmmm... here are the informations
    original folder: \nas\Qmultimedia\Picture\Events\2011.Daenemark
    compress folder is the same

    if the image on the same machine, the exif is removed too.

    the attached file is the result after compression

    Third test:
    OS: Win 8 32 bit
    Version: Caesium portable 1.4.1

    Result: The image has no exif information after compressed

    But in all the compressed images were no EXIF information available.

    i searched in the scr the codeline which copy the exif informations.
    I run this line:
    "tools\exif_copy.exe \"" + t_list.at(i) + "\" \"" + t_dir + "\" + info.completeBaseName() + t_suffix +"\"";"
    manuell in the cmd.

    The result is: Exif information was copied to the new picture.
    But it work not about caesium.

    In all my tests Caesium seems to work as intented. Quick hint: be sure to run Caesium as Administrator or the programm may not use the external .exe to copy EXIF.

    I've tried to launch the tool (from v1.4 to v1.7) as an administrator as well as on x64 and x32 Windows. So, I have to confirm that all the EXIF information is vanished after compressing in any cases.
