What should I do if I want to open my project in another computer?
All the files including the project files, final videos and original files used in your project are just saved on your computer locally instead of within this Filmora.
And there is no chance to open the project without original files, so you need to reload the project to timeline in the original computer, then select "archive project" under "file" then the files and the projects will be saved under the same folder.
Then you can transfer this folder to another computer to open it in Filmora, and please make sure that two computers share the same version for Filmora.
