Yes, the SOQL filter supports the LIMIT also for both Files and Attachments. Follow these steps:
- On the Migrate page, select "Migrate Now" and in the "Select File/Attachment" dropdown, choose the File or Attachment according to your requirement.
- Select the object and in the Filter Files by adding the SOQL conditions box, add the SOQL query with the LIMIT.
- Note: If you do not have a condition for your files/attachments you can use a generic query like "Id != NULL" as the LIMIT clause will not work without a condition.
- Click on "Search", so search results will show as per the limit set in the SOQL.
