Levent, assuming the old laptop is working the simplest and most reliable method is to go to the old laptop, run wx5, open your project, go to step 5 and export project. This will create an iwzip file. Copy the iwzip onto a USB stick and then I recommend you copy this to your new laptop. Now open WX5 on new laptop and select import, browse to and select the iwzip.

When done you project will be on your new laptop ready for editting/updating as required.

Is there a different method of copying? folders can i copy it?

If you create an iwzip this is the safest and most reliable method (it can even fix issues on the fly). If creating an iwzip do not bother including backups and previews.

However, if you wish to copy all project folders you can. Simply copy the Incomedia folder from the old laptop to the new one (normally in your documents folder).
