Hi Lobalobo,

What you need to do is to Pack Project for Export, this will copy all your source files to your specified destination.

another option

If the folder has been replaced with the original files.
When you open the project, will ask to search, it only shows the new folder's. AMD-FX 8350 / 8GB DDR3
SSD SUV400S37240G / 2-HD WD 1TB
AMD Radeon R9 270 / AOC M2470SWD
Windows 7-64 / PD16 Ultimate

I think Robert's option is much appropriate and easy to follow.

Thanks for the answers, and so quickly, but I'm afraid I don't follow. Robert says that if I "Pack Project for Export", all the source files will be copied to the new destination. But I don't need to move the entire project. (In fact I don't want to move the .pds file.) Essentially my situation is this: Currently I keep the .pds file and the source files organized independently of Cyberlink, on a hard drive that is about filled. I plan to use an external hard drive system (Drobo) that will hold only raw video, not any projects, which I intend to leave on the current hard drive. (I don't want to upset the independent organization of the source files.) So I want to move just the source files, not the .pds files. Of course, if I need to, I can move the pds files onto the other drive as well, but I wonder whether that is necessary. Thanks again.

Since I last posted, I've experimented and see now the options I have. I can move the files and then find them again (after being prompted to browse) next time I open the project, or I can Export a copy of the source files along with the .pds to any location I choose. The latter is indeed elegant, but it would require me to organize the source files under Cyberlink projects (which I don't want to do) or to keep duplicates of source files, which takes up lots of space. Ideally, Cyberlink would do what Picasa does, which is to follow the source files if they are moved while the software is open. I take it that Cyberlink won't do this.

All versions of PD "hard code" the file address within the .pds file. Actually, but sometimes not practically, the .pds file can be edited in a plain text editor to substitute the initial addresses with any "new" addresses. As far as I am aware (but I stand to be corrected) when a media file is "active" in PD it is "locked" (my word) so it cannot be moved or renamed but it can be copied.

Whilst I take your point on your preferred organisation system, the cost of storage is so cheap that there is merit in examining alternative "project based" organisation systems to minimise the issues you have identified particularly over a couple of years, as I (and probably many others) have certainly lost track of asset locations for long past projects.

The export>pack procedure is a good discipline to implement whenever possible.

The export/ pack is the better choice. Unless you can find all your files with your eyes closed............... __________________________________________
