To import your stored projects into HTTrack on your new PC, you should copy the
entire HTTrack project folder from your old PC, including all the subfolders
and files. Once you’ve transferred them, you can open the project in the new
HTTrack installation by simply pointing to the folder where the project files
are stored. Make sure the folder structure remains intact for HTTrack to
recognize the project correctly. It's also a good idea to verify the file
paths in case there are any issues with the transfer. It has ragdoll mechanics
and a ton of customisable tools, so you can make situations, try out wild
ideas, and let your imagination run wild.
