• broker.master - binary data file containing the table of all symbols available in the database. Used for quick loading of symbols. The table of symbols includes information about assignments of symbols to categories (markets, groups, sectors, industries, watch lists, indices and favorites). If you delete this file AmiBroker will re-create it because this information is available also in the individual symbol data files.
• broker.workspace - binary data file containing the information about the database settings (interval, data source used, etc), category names, global advance/decline data, etc. If you delete this file you will lost database settings and category names will be reset to defaults.

The default.awl file stored in "Layouts" subfolder inside database folder contains default LOCAL layout for this database. The default.awl file stored in "Layouts" subfolder of AmiBroker main directory contains default GLOBAL layout (used when there is no local layout present). If you delete this file then default layout will be generated based on default.layout file that is supplied with AmiBroker.
• broker.newcharts - binary file containing references between chart layouts and formula files used. If you delete it you will see "formula file empty or can not be found" in your charts because reference between chart ID and formula is lost. You will NOT however lose your formulas because formulas are separate. You will be able to reinsert them into your charts.
