Reopen.
Old file, unknown disk, a program nobody can run? Drop it here. Reopen reads the bytes, works out what it is, and tells you what it needs to open again — the machine, the operating system, the emulator. Then it writes the intake record for you.
- Read in this browser tab — nothing is uploaded
- SHA-256 fixity for every file
- Evidence you can check by hand
Identify
About 160 formats — HyperCard stacks, Director movies, Flash, DOS and Windows programs, Mac and PC disk images, flux-level floppy captures, 1990s design and DTP files, web archives, chip music.
Assess
Obsolescence risk, the original environment, and details that date it: link dates in Windows programs, Mac type/creator codes, volume names, text encodings.
Record
Checksums, evidence and significant properties in one intake record — Markdown for people, JSON for your collection system.
