♘ ChessBase Database Collector

Finds every ChessBase database 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. Copy-only: nothing is ever moved, renamed, or deleted. 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

none yet — pick your OneDrive and/or Google Drive folder

Step 2 — Backup destination

none yet — e.g. create a Chess_Databases folder and pick it

Flat (no subfolder per database) Overwrite backups that exist but differ Delete originals after copy (move) — only files verified byte-for-byte

Step 3 — Scan, copy, verify… and only then delete

Pick folders above to begin.

Verify re-reads every source file and its backup copy and compares them byte for byte — this is the proof the backup is real. Delete is only offered for databases that passed verification, and 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. Shortcut: tick “Delete originals after copy (move)” above and the Copy button does all three steps — copy, verify, then delete only what verified — in one go.

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.
