I have point shapefiles in 50,000 different folders (each shapefile file name is unique) - about 33,400 shapefiles (not all folders will have a point shapefile). I like to open the point shapefile in each of the folder into QGIS Desktop 2.2.0 map frame and then hopefully run a merge on them to get a single point shapefile layer. I tried drag-dropping from Windows Explorer to QGIS, and QGIS froze initially and continue to add the point shapefiles for several hours and didn't seem to stop. I found the Load Them All plugin (http://goo.gl/HbJhhS) that seem to specify the feature type and also specify a string filter, this plugin also didn't seem to work...
I was thinking that had I planned well, I could've automated and copied the point shapefiles into another single folder as soon as they were created and I could 've dragged-dropped into mapframe from this single folder. I don't know if this would've had worked. My analysis run took 18 days to run, so I don't want to re-run just to do that. I tried copy-pasting with Windows Explorer and it hung, may be because it was 100,000+ files...
Would you know any trick to do this?
