Using ArcGIS Desktop Advanced 10.1

I have a large CSV file (36MB with about 600,000 records) that contains single addresses that I want to geocode. The file is called "SingleAddresses.csv" The file contains 5 fields. When I first loaded the file into ArcMap, I had misnamed some of the field names, and so my field names were "SegID", "FromStNo", "Zone1", "Zone2", "Zone3". So I closed ArcMap, reopened my file in Notepad++, changed the field names to "Address", "City", "Zone1", "Zone2", "Zone3". However, when I open up ArcMap again and add the SingleAddresses.csv file again, the old (original) field names show up.

It seems as though ArcMap is caching the field names for the "C:\My Files\SingleAddresses.csv" file. If I move that file to a different directory and then open it in ArcMap, the field names show up correctly. If I keep that file in the same directory but rename it (SingleAddresses2.csv) and then open it in ArcMap, the field names show up correctly. But as long as I keep the same file name in the same directory, it still shows the old field names, even if I delete the original file and create a new empty SingleAddresses.csv file. It also still shows the old field names if I import that file into a new (different) map.

Note that I cannot duplicate this if the original file is a small file. The problem only occurs if the file that I originally use is "big"...

Is there a cache somewhere that I can delete that would eliminate this problem? It seems as though ArcMap caches the field names for a hard-coded file name. It is really annoying...

    do you have xx files in C:\Documents and Settings\<user_profile>\Local Settings\Temp or C:\Users\<user_profile>\AppData\Local\Temp resources.arcgis.com/en/help/main/10.1/index.html#//…

  • Nothing relevant that I can see... a few files with modified dates in the last couple of days, but none related to ArcMap... Commented Oct 16, 2013 at 23:12

If you see a schema.ini in the same folder as your .csv, delete it.


go to the options in arcmap and clear the cache.

  • Sorry, forgot to mention that I already tried this... doesn't work... I tried to clear the cache and then reload it without closing ArcMap, and also clearing the cache then restarting ArcMap... neither solved the problem... Commented Oct 16, 2013 at 22:50
