QuickCase:W can produce files using two commands: Generate and Update. The difference is whether QuickCase:W builds the files entirely from scratch or bases them on previously existing files.
The differences between Generate and Update are summarized below.
Generate
Produces files based on the .WIN file only. Any existing version of the files are deleted and replaced with new ones that contain only interface-producing code.
Use Generate the first time you produce the files or if you want to remove all changes made to previous versions of the files.
Update
Produces files based on the .WIN file and any additions or changes made to previously existing files. The new files contain both the interface-producing code and any code added or changed in the previous version.
Use Update all other times you produce the files.
Typically, you'll use the Generate command once at the beginning of a project—the first time you produce the files—and the Update command from then on.
