<p dir="ltr">Hi,</p>
<p dir="ltr">I have no inside knowledge of this as I am not an the development team but I remember a good post on the subject explaining that Qgis did repack the shp file when closing the file with deleted features. Is this only done on a "save as"? </p>
<p dir="ltr">The problem may be cause by another GIS, like Manifold, as I remember that this problem could lead to a totally corrupt shape file like what we as seeing here.</p>

<p dir="ltr">Hello Spring,</p>
<p dir="ltr">This has to do with the way qgis (GDAL) handles the feature deletion. Instead of totally removing them (which takes longer) it mark them as deleted.</p>
<p dir="ltr">The (not very elegant) workaround here is to save the layer to a new shapefile using save as...</p>
<p dir="ltr">Hope it helps</p>

<br />
I have been opening QGIS shapefiles in Manifold GIS and noticed that<br />
they bear very little resemblance to the same file in QGIS, in some<br />
cases. When I then saved that file in QGIS as a different file, and<br />
opened it in Manifold GIS, all the features were present and arranged<br />
as expected.<br />
<br />
On another occasion, it looked like previously deleted polygons were<br />
visible when opened in Manifold GIS.<br />
<br />
And, in another instance, when attempting in QGIS to create a<br />
polygon, that failed. Instead, portions of old, deleted polygons<br />
were reactivated instead! What is going on here? This does not look<br />
like trustworthy behavior.<br />
<br />
I tried using SpatiaLite files instead of shapefiles, but there edit<br />
and feature creation failed outright.<br />
<br />
I believe this has been dealt with earlier; could someone point me<br />
to the discussion? I did a brief search but could not find the relevant posts.<br />
<br />
Thanks very much, Cheers . . . . . . . . Spring Harrison<br />
