# File format evolvers

File format evolvers are modules geared towards transforming a file into another file format, based on current file format. The main goal of the evolvers is to prevent file content from being affected in any way by the situation of the container, that is, to carry out transformations in the files to protect the information they contain.

The clearest example is when a certain file format ends up being obsolete or discontinued, to the point of having difficulty using the file with that file format or even not being able to use it, with the corresponding loss of the information it contains. For that purpose, the evolvers will transform the file with an obsolete or discontinued file format into a more current file format.

**Note:** evolvers are used with those formats recognizable by the characterizers. A file that is not identified by the characterizers will not be able to be evolved.

All evolvers available in the system are listed in the Evolvers main screen. The system shows name, description, version, a weblink where we can find more detailed information, the origin UID identifier (the one the file would have initially), the destination UID identifier (the one it would end up having after the evolution) and access to the evolver detail.

**Note: LIBSAFE** is supplied with no evolvers. Please ask LIBNOVA consultants if you need to start evolving file formats.
