♘ ChessBase Database Collector
Finds every ChessBase database and PGN file in a folder you pick (e.g. your OneDrive or Google Drive folder) and copies each one — as a complete, intact family of matching files — into a backup folder, then verifies every copy byte-for-byte (loose PGN files are gathered together in a PGN subfolder). Deleting the originals is always a separate step you choose. Everything runs on your own computer; no files are uploaded anywhere.

This tool needs the folder-access feature of Chrome or Edge on a computer. Please open this page there (it will not work in Safari, Firefox, or on a phone).
Step 1 — Folders to scan
Step 2 — Backup destination
Step 3 — Back up, then (optionally) delete
Copy & verify copies every file into the backup, then immediately re-reads it and compares it byte for byte against the original — that comparison is the proof the backup is real, and it always runs. Delete is a separate step you click on purpose: it is only enabled for databases that passed verification, and it permanently removes the originals from the source folder (they do not go to the recycle bin — the verified backup becomes your only copy). A backup_manifest.txt listing every verified database is written into the backup folder as your record.
A ChessBase database called MyGames is really a cluster — MyGames.cbh, .cbg, .cba, .cbp… (or .2cbh/.2cbg for ChessBase 17), sometimes plus a MyGames.html media folder. If those files get separated the database breaks, so this tool always copies every same-named file together. Re-running is safe: files already backed up are skipped.
