Filformatets

Filformatets refers to the field and set of specifications that define how digital data is encoded, stored, and interpreted by software. It encompasses the encoding of content, metadata, and structure, and distinguishes between text and binary formats, as well as container formats versus single-file formats. Considerations of compression (lossless vs lossy), data organization, and how data can be reliably exchanged between programs, platforms, and over time are central to filformatet. The choice of format affects interoperability, performance, accessibility, and long-term preservation.

In practice, file formats are described by specifications published by standards bodies and industry groups. They are identified by file extensions and MIME types, and sometimes by magic numbers at the start of a file. Common examples span multiple domains: documents (PDF, DOCX), images (JPEG, PNG, TIFF), audio (MP3, AAC, FLAC), video (MP4, MKV), and data interchange (JSON, XML, CSV). Archives (ZIP, 7z) bundle multiple files, while formats like TIFF or WAV carry rich metadata and licensing details can vary.

Open formats tend to promote interoperability and archival resilience, whereas proprietary formats may require vendor-specific software or licensing. Digital preservation often involves strategies such as migrating to newer, well-documented formats, maintaining metadata, and preserving authentic copies with checksums. Filformatets remains dynamic, with ongoing development to accommodate new technologies, standards, and use cases, making it a central concern for developers, archivists, and information managers.
