Aha,
thanks for pointing that question out now, you never stated it originally. As I said and tested a drag&drop will let the new project point back to the same file, you therefor "inherit" that data and once it's changed in the old project it's changed for your project, too. VFP allows references to files outside a projects home folder and that way you can really share common things, that update for every project they are used in.
It's seldom something you want and while it sounds fancy, most often you'll just be surprised what doesn't work in an older project you come back to, just because common libs changed. Or just some records of a free table. So in that sense, I second your choice of copying the DBF.
You can see that yourself, the project manager has a status bar showing you the path and file name of a project item:
You easily spot when a file you look at would point back to the older myproject1 folder.
The situation you describe is a typical setup of a follow-up project or a new version of a software, where you can simply work on a full copy of the whole project folder, don't start off with an empty folder and PJX and add back what you need the cumbersome way, item by item.
What you can do for adding is drag & drop, but not from an old project to new project, from a Windows Explorer folder. Copy over the files you want to reuse in your 2nd project, create a new empty PJX, if you absolutely want to restart that way and then drag&drop from the file copies into the project manager to add a bunch of files in one go. That's also a well-known comfort mechanism.
For example, you might want to reuse libraries but nothing else: Then Copy over the libs folder of your old project with all vcx,vct,vcx files, create a new PJX and drag&drop from the copied libs folder into the empty project manager of the new PJX. You now have the same set of libs, momentarily. But whatever you change for your new project won't affect the old project, this now has become a separate branch of your libs development. If you drag&drop from the original project folder you will instead share the libs and have that inheritance with all its pros and cons.
Bye, Olaf.
