Dear Uwe,<br>
shape-file format is a proprietary format and we sometimes observe
that huge shape-files perform better (faster) in ESRI software.<br>
I work a lot with shape-files, but the problem you describe I never
had.<br>
If you have ArcGIS license you can manipulate the shape-file there.
If you don't have you will do it in QGIS or any other open-source
GIS software.<br>
That is all to say about competition. If you had a version of
ArcView you might have detected even more problems when working with
huge <br>
shape-files, although it always was very fast.<br>
<br>
ciao Dieter<br>

style="font-family:"Verdana",sans-serif">today I
was working on a shape dataset and I had to delete some
features. Later I opened the shapefile in ArcMap by chance
and I found that the features were not deleted. They still
did exist. I repeated the process – and got the same result.
Then, searching the internet, I found this incredible post:

<p class="MsoNormal"><span
style="font-family:"Verdana",sans-serif">It is a
well known problem (for 1,5 years!!) that <i><u>QGIS is not
able to delete shapes in a reliable way</u></i>!! I was
horrified to read this because it is the same as if a Word
processor would not be able to delete a letter from a text.
I cannot understand why the QGIS developers haven’t fix that
yet. If QGIS really wants to compete with ArcMap, they
should fix it as soon as possible. At least, the according
menu entries or buttons should be inactivated if they don’t
bring out reliable results.<o:p></o:p></span></p>
