[Qgis-user] Merging multiple features in a shapefile

[James Wood]

Paul,
If you haven't already had a reply, I would be willing to try on my computer if you can zip your shapefile up and get it to me (e-mail, Dropbox, etc...). 

You might also add a field and populate it with a single value (e.g., "1") for all records and then try a Dissolve based on that field. 

What version of QGIS are you running, from what source (standalone installer or OSGeo4W), on what OS and x86 or x64?

Using the ‘Merge Selected Features’ function seems to be limited to about 10,000 features at a time, anymore and QGIS doesn’t seem to be able to process it, or is it my computer? Is there another way to merge so many features together?
