I have 800+ shapefiles and some of them have different type of attributes. When I use Merge Vector Layers and select all my shapefiles I get "Incorrect parameter value for LAYERS" error.
When I partially select the first 20-30 something shapefiles they merge together but if I select the next 20-30 shapefiles they won't merge. I was able to get the error "has different data type than in other layers (Integer instead of String) Execution failed after 0.12 seconds" by trying to select the last 20-30 shapefiles at a time. So imagine this might be the cause of error when I try to merge them all together at once.
What can I do to merge all these shapefiles, without losing data? I just want to merge everything together, even if there will be duplicate fields in the attribute table. What can I try to merge these files? What could be the culprit here?
