aptana - Project location must be empty when creating a new project? -

good afternoon.

i've tried find answer question can't seem find one.

i'm using study guide teach myself html5 , css3. study guide comes material use exercises.

the first step me create new project using provided material every time try told folder have set project not empty.

the steps told use follows:

when complete step #6 receive following message:

 folder 'c:\target' not empty

at point unable click either next or finish button.

am missing something? there approximately 20 chapters worth of exercises each exercise consisting of multiple files. have import them individually?

i using aptana studio 3, build: 3.4.0.201304151603 in windows 7 professional 64bit.

thanks.

instead of choosing file > new > project, use file > import > existing folder new project.
