Script for deleting Hidden Layers which are not used in any Layer Comp?

[Guest]

Hello.

I've turend the web upside down searching for a script that would do the following:

1. Search through all the layer comps in the document
2. Check which layers are hidden on all Layer Comps
3. Remove/mark with color the layers found.

If anybody can provide a script that would do such a thing - it would be highly appreciated.

Regards,

Fade.

This should mark those layers Red...

function main(){

Thanks for your quick reply, Paul!

What extension should I save this file with? .js?

[Paul Riggott]

The norm is ".jsx" the script will require Photoshop CS3 or better.

It's best to use ExtendScript Toolkit (this gets installed with Photoshop) to copy the code and save it out.

[Guest]

Great! It works!

Now what is the change needs to be done in order for the layers to be deleted instead of marked in red?

[Paul Riggott]

This script will delete those layers....

[Guest]

Thank you so much!

You've have just made my time so much more productive!

[Guest]

Additional question.

After the script has finished its' business (which id does perfectly - thanks again!), there are lots of empty folders left.

Is there a way to add a part that would get rid of those too?

[Paul Riggott]

That's a bit tricky as there could be nested folders that are empty.

I have added the code so that it will do three passes on layersets this can be increased if required, hope this ok.

Also added an alert to say that it has finished.

If you deal with a lot of layercomps, there are a couple of scripts here that might be of use to you?

[Guest]

Perfect!

Thank you very very much!

[Gpinner]

Thank you very much for providing such a useful script.

[davidhmorgan]

Thanks for creating this, it is very useful!

[yuvalc70027833]

Hi,
After generating the text to jsx. file and paste it in the script folder,
I opened psd file and tried to run the script ( selection first).

I keep getting this error message:
What am i doing wrong?
Thanks
Yuval.

[JJMack]

Open your script file in a test editor  capture the screen and post the screen capture,  I think you messed up creating the script.  Line 1 should be

1. function main(){ 

that function is used in line 33

         33.  main();

I do not see the string FasdUAS in the thread????

[schroef]

I thought i add the working version again here, all scripts added before the forum redesign are broken.
This script works for me, only small issue is when layers are clipped to layers below. SOmetimes it causes an issue them not being deleted.

So I've got an issue where in I have a .PSD file with hundreds upon hundred that that is 3.3gb when open, running in PS CS6.  When I run either the mark red or delete script, it looks like it selects the entire list of layers, but then freezes. I 've opened task manager and the amount of processor usage varies, so I'm thinking it might be doing something but after just now letting it run for a good 30 minutes, no result.

Am I out of luck with regard to using to using either of your scripts or do you think there might be something I'm missing? Just for giggles I've tried both running the script by placing it into the "presets/scripts" folder and simply browsing to where I saved it from the extend script tool.

Any thoughts would be very much appreciated.

Cheers,

Patrick

Thanks for this great script.

A thought on an improvement: it seems that if you have a layer group set to visible with all of its layers turned off, the delete script leaves these layers intact. Is there any way to script this at the layer level as well, or could this be a bug?

Ive been using this one for years. THough my version is a little different. I guess the new FOrum also wrecked most scripts in the loops.

My version does delete all hidden folders as well

Hi, I'm a little late to this post, but the script here works great.

However, I'm wondering if it's possible to have a script that would instead go through all layers & smart objects and delete hidden layers.

That would be amazing if possible?

Thanks

Chris

Chris, scripts previously posted in this topic do just that, go back to the top of the thread and work your way down (post #5 and or #8).

Thanks for your reply Stephen, however I have tried both of these scripts, and both delete all layers within a PSD, regardless of whether there are smart objects with layers visible or not, and it also deletes visible layers that are not part of any smart objects.

What I was hoping for, was a script that would only delete hidden layers, both standard layers in a PSD and those that sit within smart objects.

Edit: Just to be clear I am not using layer comps

Cheers

[Stephen Marsh]

Ah, thanks for clarifying Chris, as this topic is all about layer comps, I was of course focused on that aspect. I’d suggest that you start a new topic dedicated to your different but related question.

[schroef]

EDIT
Sorry just read you dont use layer comps. Easy fix to get this one to work. Simply make 1 layercomp when your design is done, than run this script. It will work as intended and not delete those items you talked about.

Earlier response

Did you try my version?

Ive used this one since i updated and i dont have any issue other than that clipped items sometimes are kept.
I useSmartObjects a lot, i always linkin images and use the SmartObjects in 98% of my files.

I use layercomps when i make designs and then when final version is chosen i clean this file and save it as a new version. I dont have any issues with SmartObjects being deleted.

My latest adition removes the history so its faster and saves memory, it also enters fullscreen so it doesnt need to redraw the UI.

Have a try and let me know if this does work

On second thought, you dont have actually quite a simple method. If you use the layer panel filter options. You can show only hidden then delete them. If you then select all and delete them. You can basically make this yourself with scriptlistner

I found this as i was researching it a bit. I tried scrriptlistener but it does show items from the filter menu. They are not exposed enough to be usefull.

Someone else had the same question in this forum post

Ive set the author to the poster of that thread, for me the script works
After checking photoshop, its the same code when you run Headermenu . Layers > Delete > Delete hidden. Which means you can also make it an action and give it a shortcut if needed

If you need to also delete nested layers inside smartobjects, that becomes a bit more difficult. You could try making a function which loops over itself.
