You want to make an export of thousands of files, and you get the message: "No instance available".
Solution
When you see the message "No instance available", this tells you that the amount of files is too high for the export.
Method
You use the last name to create a smaller list by splitting the export (no more than 2000 records at a time). Here's how:
Make your regular selection of candidates/contacts.
Add to the search filter: Last name | starts with | a b c. You now have a smaller list — send the e-mail or export the records.
Repeat this for: Last name | starts with | d e f g h i.
Repeat this until you've covered the whole alphabet.
The exact number of files you can export with a single action can't be determined in advance. 2000 is a guideline — in some cases the system can handle a bit more, in others less, depending on how much data needs to be retrieved.
