Hello, The simplest way to get access to a history or workflow in file format is to download from the UI. This creates an output file that can be archived and/or loaded into other Galaxy instances. However, if you want to explore the data itself, then you will want to look in the database associated with your Galaxy instance. This database contains the tables that link groups of tools/data associated with workflows and histories. If you have a basic install following these instructions, then your data is organized using the "Basic Configuration" with a SQLite database: http://wiki.g2.bx.psu.edu/Admin/Get%20Galaxy If you have upgraded to a "Production server", then your database is likely an alternative, such as PostgreSQL: http://wiki.g2.bx.psu.edu/Admin/Config/Performance/Production%20Server The general architecture is explained here: http://wiki.g2.bx.psu.edu/Admin/Internals/Implementation%20Info The "Data Model" of the database is in this wiki: http://wiki.g2.bx.psu.edu/DataModel Next time, please only send questions to one of our mailing lists (one question, one list). For this case, the galaxy-dev list was the best choice. http://wiki.g2.bx.psu.edu/Support#Mailing_Lists The development community is welcomed to add in more comments/detail to this thread.

Dear Galaxy Developer,

where is the "history/workflow" file stored in the local machine? I mean the real file store in the disk instead of browser access.

Thanks and Best regards
