I would delete the Import.log file, then see if FileMaker creates another one. I delete those files all the time, as I am only interested in the things I've done recently.
I have deleted the import.log file and tried a new import. No new import.log file is created (I looked in the folder with the DB file, on the desktop, and in my Documents folder).
Someone helped me in another FM forum. It seems that the import.log is updated only if you are importing records which create a NEW DB file, or if you are importing scripts, custom functions, and likely other types of imports. Importing records to an EXISTING DB file does NOT update the import.log file.
Too bad. Seems like it would be useful to know which records were imported successfully or not...
Is this something that FM will be fixing or adding any time soon???
