Track down documents scattered across my accounts
Every matching document found across Gmail and Drive, organized into one folder
Track down every [document type — e.g. W-2, insurance policy, signed contract, invoice] I have from [period, e.g. 2014 to now], wherever they live. Search my Gmail (including attachments) and Google Drive [plus anywhere else I name — a vendor portal, iCloud]. Search smart: the obvious name plus variants, sender names, and the time of year they usually arrive. Expect an uneven trail — some years may have two documents, some none. Collect everything into a Drive folder [folder link, or create one], renamed consistently as [year — source — type]. Build an index sheet with a row for each expected period: the document, where you found it, and a link — so gaps are visible. Mark missing periods MISSING with your best guess where else to look. Don't stop at the first hit per period; confirm completeness against the index before you finish.
