About Collection Manager
Collection Manager creates, edits, and exports osu! collections, including support for taiko and osu!mania modes. It loads collections from an osu! install, from .db or .osdb files by menu or drag-and-drop, and from previously uploaded osu!Stats collections. It saves in .db or .osdb format, can overwrite the osu! collection, export each collection to a separate file, or export plaintext lists of all maps or missing maps.
If the osu! folder is not configured, .db entries show hashes instead of map names, direct open and save to the osu! collection and the beatmap listing are unavailable, and plaintext lists cannot be imported back into collections.

Collection Manager FAQ
How do I download Collection Manager for Windows or Linux?
Download the latest release from Releases under the Assets dropdown. Use CollectionManagerSetup.exe for Windows; through Wine on Linux you likely need CollectionManagerSetup_linux.exe, which may also apply to macOS.
What if Collection Manager does not find my osu! folder?
Select Load beatmaps from a different location and locate your osu! folder manually. Without a configured folder, .db collections show hashes, direct open and save are unavailable, and the beatmap listing is unavailable.
