I had this question after viewing Photoshop CS6 Export Multiple Layers with Fixed Top Layer Effect on All
. I have an extremely large (383mb) psd file with over 200 layers. I created the file using photoshop CC (current verison is 2019). In it I have several base layers that I use for the background for the other layers. So if I export the layers as a png file I might select layer 6 (which has several styles applied to it) and layer 10 as one image, then layer6 and layer 11, then layer 6 and layer 12, etc. Sometimes I select the base layer (layer 6) and 2 to 3 other layers in combination. I want to be able to automate this as much as possible. I could save a copy of the psd and then flatten each layer so there would never be more than 2 layers selected (the base and the one I am selecting). There must be some way to do this within photoshop! Any ideas would be appreciated (I also wouldn't mind getting this large file downsized a little - over 380mb is far too large).
