file summary infos / EXIF causing win explorer to hang

[Olaf Doschke]

Hi everyone,

I don't know if this is already a known issue. But I had
some AVIs causing win explorer to hang, just by dis-
playing a directory containing these files.

This happens when hovering with the mouse over a file
when the file summary /EXIF info should be displayed
as a tooltip text.

This also happens, if the explorer is just open in a directory
containing such files and even when the explorer is mini-
mized, set as background process, so it seems the explorer
prereads this EXIF/ summary informations.

I found one program that reproducably creates such files:
CamStudio, a screen capture program generating avi videos
from your desktop (nice for producing screencasts):
http://www.camstudio.org/

It seems their lossless codec you can use is not storing EXIF
infos or storing them wrongly.

The error appearing is a memory access error and does not
even cause the usual "report error to Microsoft" dialogue.
The win explorer just dies and then after even the taskbar is
gone for some seconds windows (xp home edition) comes
back to normal, missing the died windows explorer. I know
the desktop/shell is also just a win explorer task, so that may
be explained by that.

Is there a way to turn this feature to display summary info off,
so that such corrupt files don't cause system instabilites? Or is
there a way to edit this summary and correct errors?

I already have uninstalled CamStudio, as I can't distribute videos
that cause such problems. But it's not the only files I had that
cause it, so I'm interested more in an overall solution.

I searched groups.google.com, but didn't find anything on this
issue. Thanks for any tipp.

Bye, Olaf.

Olaf,

See if there are any third-party utilities which can remove the EXIF data
from AVI files. Check www.snapfiles.com and www.majorgeeks.com
