Transferring Project to another computer problem

I copied the folder that contains my project to another computer running Animate Pro 3, and for some reason lots of my drawings and keyframes all dissapeared.

If there’s something else I need to copy to move these please help quick! have class in an hour and need it there! thanks!

This problem can appear when moving the project off the internal hard drive. Other types of drives are not responsive enough to keep-up with all the small files that a typical project contains. The solution would be to zip/compress the project folder before you move it from the internal hard drive and send instead the zip file. This also has the benefit of making the project take-up less space for faster file transferring.
