Is it possible to divide one Photoshop document into multiple source files?

I am new to Photoshop and therefore in need to get familiar with it fast.
I wonder, if there is a way to divide Photoshop like a website, to make every picture (such as a website logo) editable seperately, so when I edit it, it automatically updates in the master Photoshop document.

This would be very useful to me, if Photoshop had something like this, for organization and ease of use.

I am making a website and I just have too many layers to manage.

Thank you in advance

Answer

Sounds to me like Smart object is exactly what you’re looking for.


For example: Your main document may have a button object that is formed with multiple layers. You can select all of those layers and combine them into one smart object.

When you go edit the smart object, another document opens up where you have only those layers showing. Then you can just save the changes and go back to your main document.


There’s quite a lot to know about smart objects, so you might wanna to read some more about them.

On that note.

Here’s a couple quotes from that page (just in case).

About Smart Objects

Smart Objects are layers that contain image data from raster or vector
images, such as Photoshop or Illustrator files. Smart Objects preserve
an image’s source content with all its original characteristics,
enabling you to perform nondestructive editing to the layer.

You can create Smart objects using several methods: by using the Open
As Smart Object command; placing a file, pasting data from
Illustrator; or converting one or more Photoshop layers to Smart
Objects.

With Smart Objects, you can:

  • Perform nondestructive transforms. You can scale, rotate, skew,
    distort, perspective transform, or warp a layer without losing
    original image data or quality because the transforms don’t affect the
    original data.

  • Work with vector data, such as vector artwork from Illustrator, that
    otherwise would be rasterized in Photoshop.

  • Perform nondestructive filtering. You can edit filters applied to
    Smart Objects at any time.

  • Edit one Smart Object and automatically update all its linked
    instances.

  • Apply a layer mask that’s either linked or unlinked to the Smart
    Object layer.

  • Try various designs with low-resolution placeholder images that you
    later replace with final versions.

You can’t perform operations that alter pixel data—such as painting,
dodging, burning, or cloning—directly to a Smart Object layer, unless
it is first converted into a regular layer, which will be rasterized.
To perform operations that alter pixel data, you can edit the contents
of a Smart Object, clone a new layer above the Smart Object layer,
edit duplicates of the Smart Object, or create a new layer.

To create smart object from layers:
– Select bunch of layers.
– Right click one of them and choose Convert to smart object.


Edit the content of a Smart Object

When you edit a Smart Object, the source content is opened in either
Photoshop (if the content is raster data or a camera raw file) or
Illustrator (if the content is vector PDF). When you save changes to
the source content, the edits appear in all linked instances of the
Smart Object in the Photoshop document.

  1. Select the Smart Object from the Layers panel, and do one of the
    following:

    • Choose Layer > Smart Objects > Edit Contents.

    • Double-click the Smart Objects thumbnail in the Layers panel.

  2. Click OK to close the dialog box.

  3. Make edits to the source content
    file, then choose File > Save.
    Photoshop updates the Smart Object to
    reflect the changes you made. (If you don’t see the changes, make the
    Photoshop document containing the Smart Object active).


Duplicate a Smart Object

In the Layers panel, select a Smart Object layer, and do one of the
following:

  • To create a duplicate Smart Object that is linked to the
    original, choose Layer > New > Layer Via Copy, or drag the Smart
    Object layer to the Create A New Layer icon at the bottom of the
    Layers panel. Edits you make to the original affect the copy and vice
    versa.

  • To create a duplicate Smart Object that isn’t linked to the original,
    choose Layer > Smart Objects > New Smart Object Via Copy. Edits you
    make to the original don’t affect the copy.

A new Smart Object appears in the Layers panel with the same name as
the original and “copy” as a suffix.


One thing that I forgot to mention.

There is no straight up way to unfold a smart object back to bunch of layers in your main document. If you need to do that at some point, you will have to duplicate the layers from your smart object document into the main document.
