Query & Replace Psd File Textures

[kart]

Hi All,

I am trying to replace PSD files textures for bunch of shaders.
I have created shading networks with diff. layers from a psd file and want to replace the old file with new one which has the same set of layers. Selecting each file node and changing the texture name would be lengthy process.

Is there any way I can query a psd file and replace it with new file?

Thanks in advance.
