resizing PSD files without merging layers

[kay_san]

Hi, I wonder if I can resize the psd files without having the layers all merged/flattened.
the folder trees should be kept as they are, and I'm not sure what would be the best way to batch the files other than to do it in photoshop, which takes forever to do. TT

Any advice would be helpful. Thank you in advance.
