Pack files (.hexc)

A .hexc file is a complete, lossless copy of one pack - every asset, layer, frame, tag, face, palette, and color, exactly as it sits in the editor. Export one to keep a backup, send your work to someone else, or move a pack between computers. Importing it brings everything back the way it was.

Hexcalibur keeps your work only in your browser, so a .hexc file is the way to back up a pack or take it somewhere else.

When to use it

• Back up your work. Your packs live in this browser. Clearing your browser’s storage erases them. A .hexc file on your disk is a safe copy you control.
• Share a pack. Send a friend a .hexc file and they can import the whole pack and keep building on it.
• Move between computers. Export on one machine, import on another - no account needed. This also works for moving between browsers on the same computer, since each browser keeps its own packs.

Export a pack file

1. Open the pack you want to export.
2. In the top bar, open the File menu.
3. Choose Export Pack File (.hexc)….

Your browser downloads a .hexc file named after the pack. It contains the active pack and all of its assets.

Import a pack file

1. In the editor’s top bar, open the File menu and choose Import Pack File (.hexc)… - or, from the pack browser, click Import Pack next to the New Pack button.
2. Pick a .hexc file.
3. Review the preview - the pack’s name, cover, and how many assets it has - then choose Import Pack.

Importing always creates a new pack. Your existing packs are left untouched, so importing is never destructive. After it finishes, the editor switches to the imported pack.

Good to know

• Tilemaps travel whole: a map’s tile arrangement survives the round-trip, still linked to the pack’s tiles after import.
• A .hexc file isn’t tied to any browser or computer. Any copy of Hexcalibur can import it.
• .hexc is for moving packs in and out of Hexcalibur. To get textures into a game or another tool, use Export instead.
