# File format evolution jobs

Evolution jobs are the processes by means of which **LIBSAFE** evolves file formats based on their current format.  &#x20;

The main screen of evolution jobs will provide:

* Access to approval of object evolutions proposed automatically through the link _Approve evolution of objects selected by the system_, found at the top of the page.
* Access to manual creation of evolution jobs through the link _Create manual evolution of objects_, found at the top of the page.
* A list with all the information on evolution jobs, regardless of their progress status (creation, execution, finished, waiting for user intervention).&#x20;

Every list will provide access to the detail of the related job. They also carry on their header a system that will filter by job identifier and range of date of creation, which will allow limiting the number of results shown.
