SolidWorks Pack and Go overview

File >> Pack and Go collects all referenced files (parts, drawings, sub-assemblies) from your assembly and drawing files. It's a great way to duplicate a project if you need to make changes to the design, or move files between computers - you can even create a zip file directly from the dialog box.

You can also use Pack and Go to rename individual files and their destinations (by double-clicking in the respective fields), or you can use the Select/Replace... button to make bulk or batch changes to all of your files - e.g. replacing a specific text string such as a Job number from every single file with a new one.

Pack and Go will create the new files while maintaining file references between all of your part, assembly and drawings, even if names and folder structures have changed.
