When I want to use the "export layers to files" function in Photoshop, there's always a prefix of the layer number sequence. For example, I'll export a number of layers (to pngs) and the prefix is _0001, _0002, _0003... I don't think this feature necessary in most cases. I already removed the standard 'File Name Prefix' in this dialog box. But, that doesn't hold true after export. Is there a way to quickly remove this default script?
Or if not possible, is there any recommendations on advance 'file renaming tools' like GREP in InDesign?
Both Bridge and Lightroom can quickly rename the files for you. As long as all the files are not the same name, you should be fine.
If they are the same name, you could use a date for a unique name, or change the sequence format. Ex. number of 0's before or after the actual number.
For Photoshop CC 2018 go to:
Applications/Adobe Photoshop CC 2018/Presets/Scripts/Layer Comps To Files.jsx
Once you open the file, go to line 209 and comment it out.
I've attached an image for reference.
Once I did this, Photoshop stopped adding the sequence number prefix to when I export Layer Comps To Files.
