OldFileOpener, for the files modern software abandoned

Field notes

The service describes a byte-level identification step before conversion, rather than trusting a file extension, and says it reports which parts survived. Its catalog spans office formats, disk images, obsolete media, mailboxes, and text encodings; examples include CorelDRAW, dBASE, Outlook PST, MIDI, and Windows Media files. A separate Drive Rescue workflow is described for zipped folders, with the original directory structure retained and unconvertible files accompanied by opening instructions.
