<p>Hi Bob,</p>
<p>Yes file names passed in that way can have unknown things
happening behind the scenes :-)</p>
<p>PowerShell can help here, but Dos can still do it effectively and
quickly, as you are working in it, here are some dos shell command
lines you could try executing. <br>
(If you find this working, it could be converted into a batch
file, once any other needed modifications have been worked out
later. Note that %-s would need to be changed to %% in a .bat
batch file.)</p>
<p>I downloaded a working copy of from exiv2 from<br>
<a class="moz-txt-link-freetext" href="https://exiv2.org/download.html#license">https://exiv2.org/download.html#license</a></p>
<p>Looks like you got your option commands from(?):<br>
<a class="moz-txt-link-freetext" href="https://exiv2.org/sample.html">https://exiv2.org/sample.html</a></p>
<p>Locally, open a dos prompt up at the top of the directory tree
you want to explore. <br>
If all you can see is PowerShell, then when that opens type :-<br>
</p>
<p> cmd <Enter></p>
<p>Again, make sure you are in the top of the directory tree you
want to explore.<br>
</p>
<p>The overall system PATH does not appear to need alteration, as
exiv2.exe when called directly, appears to find all that it needs
locally. <br>
So first set your exiv2.exe file's full location, change the path
to fit your setup, using quotes especially if you have any spaces
in your .exe directory path. :-<br>
</p>
<p>set
exiv2FullPath="G:\utils\exiv2-0.27.6-2019msvc64\bin\exiv2.exe"</p>
<p>And alter the below to your situation (change the *.exts to
whatever you need, fewer or more, leaving a space between them):<br>
</p>
<p>Then execute each of these lines one after the other :-</p>
<p>del results.txt & for /r %i in (*.jpg *.jpeg *.png *.crw
*.dng) do %exiv2FullPath% "%i" -pp -q >> results.txt <br>
</p>
<p>find ": 0 x 0" results.txt > possible_corrupt.txt <br>
</p>
<p>notepad results.txt & notepad possible_corrupt.txt</p>
<p><-- Try the above first, but if necessary, in the second
command line above, change ": 0 x 0" to whatever is signifying
your corrupt file(s) as shown in the file: results.txt. Copy and
paste the needed text out of results.txt between the "quote marks"
as I suspect otherwise invisible tabs U+0009 could be being used.</p>
<p>Close the notepads: for results.txt and poss_corrupt.txt - when
you want to run the command again over the same directory tree.<br>
</p>
<p>At worst you can scan though the file: results.txt manually in
notepad. <br>
</p>
<p>N.B. <br>
Just note that the file: results.txt will get overwritten each
time you run the main command, so copy or rename it first if you
want to keep it :-)<br>
</p>
<p>Hope that this will help you,</p>
<p>Kindest regards,<br>
Paul<br>
</p>

I think that could be a good solution to find corrupted jpeg.
Based on this I have some thought<br>
- as exiv2 is native with Digikam, I guess such error could be
visible? <b>Is there some "debug level" or some logs
somewhere that could report such errors ?</b><br>
- I'm not expert on coding so don't know how to translate such
command to a recursive search on a set of folders?<br>
- seems to apply to raw also , but I don't have corrupted raw
to perform the test<br>
</font> <font face="Times New Roman, Times, serif"><br>
thanks to share your feedbacks and may be other option<br>
