Thank you for your post.
How many database files do you need open?
Please keep in mind that each database file can hold a large number of tables. If you had 100 database files with only 50 tables each, that's 5,000 tables.
True, but if your files started out as "ye olde one table = one file" files from back when filemaker couldn't do multi-table files, merging them can be a major challenge. :smileywink:
