Which process aids in avoiding obsolescence in digital files?

Format migration is a crucial process in digital preservation that helps to mitigate the risk of obsolescence in digital files. As technology evolves, certain file formats may become outdated and no longer supported by current software or hardware. By migrating files to more contemporary formats, archives ensure that the data remains accessible and usable in the future.

This process typically involves transferring data from an old format to a newer one that is still widely accepted and can be managed with current technology. For instance, migrating from a proprietary file format to an open, standardized format not only helps to maintain the integrity of the information but also protects against the risk of losing access due to changes in technology.

In contrast, data compression primarily aims to reduce file sizes and may not directly address usability or access issues. Regularly updating software is important for security and functionality, but it does not ensure the longevity of file formats. Public domain access facilitates sharing and legal use of materials but does not prevent file obsolescence. Format migration directly addresses the need to keep digital materials functional as the technical landscape changes.
