What kind of file-type are you trying to select? psdx?
Thank you for answering yes I believe so I am using psdx
How do I create a different type of file
So I can import them in Photoshop touch and use them in Photoshop touch
For Photoshop touch project
I'm new to Photoshop please help thanks you
A psdx (PS Touch file format) file cannot br inserted as a layer. You can upload a PS Touch file to the creative cloud as jpg or png and go from there.
Or when you have both psdx files on your tablet you can copy and paste form one to the other as well.
hope that helps.
Adding to what Guido said, you can create a *new* PS Touch project from a PSDX file in Creative Cloud but you cannot insert it into an existing project.
When out in the project file selection UI, use the "new image from" icon in the middle lower right, then point your way to Creative Cloud. The PSDX file will be imported, layers and all.
