I have a large locator file I need to create. I put the data on a drive with ample space and open a project in ArcGIS Pro 2.7 to that same drive. Used the Create Locator tool to build the file, but, no matter what settings I look at or configuration changes I attempt to make, it processes on the C drive where there is no space and I ultimately run out of space in short order.
ERROR 003088: Not enough disk space to build locator.
Has anybody run into a similar situation and know how to navigate around the issue?
Looking forward to your advise.
The tool documentation Create a locator—ArcGIS Pro | Documentation has:
When creating an address locator with reference data that contains millions of features, it is necessary to have at least 3 to 4 times the size of the data in free disk space on the drive containing your temp directory because files used to build the locator are written to this location before the locator is copied to the output location. If you do not have enough disk space, the tool will fail at some point during execution when it runs out of space. Also, keep in mind that when creating very large locators, you should have a machine with enough RAM to handle large memory-intensive processes.
I would guess it means the system temp folder is being used a staging location, e.g.
I think this can be changed with a system environment variable, but am stretching my knowledge a bit in this area. Hopefully this can give you a lead though.
