How can I find a file by internal ID?

Just open any file from file cabinet and click edit. When page load check the address bar and change the current file id with the one you want to search for, then click Enter and magic happens netsuite

Fair point.

There is also a setting to turn on Internal ID for all lists. I’m not sure that works for files but it works for most records

Unfortunately, file cabinet search doesn't let you search by ID -If It didn't got any update- 'cause I'm still searching It old ways :d
