Importing Photoshop Files

Continuously experiencing problems importing Photoshop files. Software sporadically imports as single layer file, even with selection set to “All Layer Images”, and all layers grouped in uniquely named folders. Sometimes it works if I create a new PSD file copying the same layers into the new file and then saving. Sometimes it doesn’t work at all. Using Photoshop CC. Any ideas?

What is common to the files that import and those that don’t? Are you perhaps using special characters in the file names or folders you are importing from?

Thanks rkriz, your answer worked for me. I had troubles importing illustrator-files. In the foldername was a ‘>’. When I removed that ‘>’ I could import the files. At last. So thanks!
