Module information
Modules BESA Research Basic or higher
Version 5.2 or higher

One of the most important rules in BESA software is that the original data will never be changed during data processing (unless user explicitly want to do it by himself). All the changes (i.e. signal processing like filtering) performed in BESA are kept in PC memory and not saved to the file. Such approach has a drawback, that all the settings have to be regenerated whenever the data file is reopened. Therefore to keep all the settings and reload them whenever file is opened BESA saves the additional files beside original one (with the same name, but with different file extension). Note that Such approach has one additional advantage: whenever user want to start his analysis from a scratch he or she just need to delete file responsible for particular setting (or all files to get completely initial state). Therefore good understating of BESA file nomenclature might be useful for advanced BESA users.
