One-by-one upload automation depends on the next file appearing in the same predictable place after each selection.
Control the source folder
Create a sorted source folder and record one complete choose-upload-confirm-return cycle before repeating the batch.
Record browser and Finder together
MacroLoop can handle the browser and Finder dialog path. Number the filenames, use list view, and test what the dialog selects after the first file has been uploaded.
Keep publication decisions manual
Do not automate publication, rights declarations, or public sharing without review. Confirm each filename and upload status.
THE TAKEAWAY
Stable file order and visible upload confirmation are the foundation of a safe batch.OFFICIAL REFERENCES
