| Aug 20, 2021 at 8:47 | comment | added | Cookie | @Babel I've tried batch mode, but I still need to add hundreds of layers one by one. Is there a way to add a folder of layer onto the current working space? | |
| Aug 20, 2021 at 8:29 | comment | added | Cookie | @Vincé Thanks for the reply. I've done merging all the data into one. But the problem is if I run the count points in polygon, it cannot distinguish how many of EACH names in polygon. | |

| Aug 20, 2021 at 6:44 | comment | added | Vincé | Hi, for me it sounds, as if it would be more efficient, to FIRST merge/concatanate all your CSV-files PRIOR to IMPORTING them. Subsequently you can do your analysis on a single file. With R it's a mattter of 5 lines of code and you will finde plenty of soltuions online. Maybe there's other ways to batch-concatanate CSV-files with the same column-names? | |
