<p>Hi Mira,</p>
<p>It is highly unlikely that any data can corrupt/modify QGIS as a software. It could crash it, but it can't modify binaries/libraries of QGIS.</p>
<p>Not knowing about your situation - are you sure that your whole system was in a healthy state? Perhaps one harddisk or partition was full? That could explain such a behaviour.</p>

Could it be that this messed up something internally that it even affected shape files outside of this folder?<br /><br /><span style="white-space: nowrap;">Cheers,</span><br /> Mira<br /><br /><span style="white-space: nowrap;">On 25/11/16 18:17, Nicolas Cadieux wrote:</span>
