Opening a PackageFile
To open an existing package file, select “Open” from the File menu, or click the “Open” icon in the toolbar. This will open the Open Package Files dialog. Once you have navigated to the appropriate directory, select the package file (.epk3) you want to open and click the “Open” button.
The PackageFile that is currently open in the PackageFile Editor can be saved by selecting "Save" from the File menu, or by clicking the Save icon in the toolbar. This will open the Save PackageFiles dialog. The default directory for package files in E-Prime is My Experiments\Packages. In addition, a custom directory can also be selected for package files.
PST recommends that package files be saved in a sub-folder that shares the same name as the PackageFile itself. For example, if your package is named "PST", you could create a separate directory for the file (e.g., C:\Program Files\PST\E-Prime\Program\Packages\PST).
Once you have navigated to the appropriate directory in the Save PackageFiles dialog, enter a file name (by default, this will be set to the value of the Package Name property specified in the Package component with an *.epk3 extension) and click the "Save" button.
The PackageFile Editor will automatically create a BackupCopies folder in the directory that the package file is saved to. Each time the package file is saved, the PackageFile Editor will place a backup in this folder. Backup copies will be named the same as the original package file, except that a numerical extension will be added. For example, if a package file named "PST" is saved in C:\Packages\PST, the PackageFile editor will create C:\Packages\PST\BackupCopies the next time the package file is saved, and a file named PST. epk3.1 will be placed in the BackupCopies folder. Should the original package file become corrupt, it can be recovered by changing the name of the backup copy from "PST.epk3.1" to "PST.epk3" in Windows Explorer.
