File Browser

Added in Version 22

Choose General File Browser from the File Menu to open the File Browser. The File Browser is a special dialog that can be used to choose a list of file paths on your computer in which you would like to search for PowerWorld related files. The File Browser dialog is shown at the end of this help topic. The first thing to do when using the File Browser it to choose a list of paths in which to search for files. This is done in the exact same manner as done with the Auxiliary File Browser dialog. For help on the buttons at the top of the File Browser which are used to specify the search pathsee the Auxiliary File Browser help topic.

After this is a row of check boxes which allow you to choose which file types to search for with choices of PWB, PWD, AUX, AXD, TSR, RAW, and EPC. We expect to add additional file types in the future, but these are the available file types as of the release of Simulator Version 22. After choosing a list of search paths, Simulator will search all the files in those search paths for files with the extensions chosen.

Once the list of files is populated in the table, you may right-click on this list and choose options either Open Selected File or Delete Selected Files.

There are certain fields which are available for all file types and these fields are self-explanatory and listed next: File Date Modified, File Directory, File Extension, File Name, File Path, File Size (KB).

For PWB, EPC, and RAW files, while searching PowerWorld peeks inside the files to collect summary information about each file. The File Browser can then provide special summary information which can then be searched, sorted, and filtered to help you find files of interest to you. A descriptions of each file type any special features for that file type is described in the next table.

Type	Description	Special Features	Special Fields Available for PWB Files saved in Version 22 or later
PWB	PowerWorld Binary Case	The Case Description will be shown at the bottom of the dialog in the Header Section Any Case Comments will be shown on the bottom right portion of the dialog when choose a PWB file. In addition to these, you may configure the case information displays to show columns that will be populate for PWB files as follows: Header field will show the Case Description in the form of a field which will allo you to use either advanced filter the contents of the Header or use the case information Search for Text feature to help find the file you're interested in EXE Build Date when saved field will show the EXE file creation date of the pwrworld.exe file used to save the PWB file. Onelines field will show a list of PWD files that are configured to automatically open when load this PWB file. Dozens of other Fields: Starting with the PWB format of PowerWorld Version 22, we also store a large amount of summary information at the beginning of the PWB file which can then be parsed by the File Browser to show information in columns of the case information display. These include the columns shown to the right which mimic the same fields available on the Case Summary Dialog. Using the sort features of the case information displays can be especially helpful.
