One of the most important rules in BESA software is that the original data will never be changed during data processing (unless the user explicitly want to do it by himself). All changes (e.g. signal processing like filtering) performed in BESA are kept in PC memory and not saved in the file. That type of approach has a drawback, since all settings have to be re-generated whenever the data file is reopened. Therefore to keep all settings and be able to reload them whenever a file will be opened, BESA saves additional files beside the original one (with the same base name, but different file extensions). Note that this approach has one additional advantage: whenever the user want to start analysis from scratch he or she just needs to delete the files responsible for a particular setting (or all files to get back to the initial state). Therefore a good understanding of BESA file nomenclature may be useful for advanced BESA users. | One of the most important rules in BESA software is that the original data will never be changed during data processing (unless the user explicitly want to do it by himself).

One of the most important rules in BESA software is that the original data will never be changed during data processing (unless the user explicitly want to do it by himself). All changes (e.g. signal processing like filtering) performed in BESA are kept in PC memory and not saved in the file. That type of approach has a drawback, since all settings have to be re-generated whenever the data file is reopened. Therefore to keep all settings and be able to reload them whenever a file will be opened, BESA saves additional files beside the original one (with the same base name, but different file extensions). Note that this approach has one additional advantage: whenever the user want to start analysis from scratch he or she just needs to delete the files responsible for a particular setting (or all files to get back to the initial state). Therefore a good understanding of BESA file nomenclature may be useful for advanced BESA users.
