How do you organize your graphics and photoshop files?

This link gives you file locations of various assets like brushes.

Photoshop CS6 preference file functions, names, locations

Brushes are the only presets I have a lot of, so what I do is rename them in the Windows folder, so that they meaningful names in alphabetic order.  I try to leave enough of the original name to identify where they came from.  The Preset Manager, and improved Brush Management system, are also useful keeping things in order.

With graphic elements, I use the CC Libraries. These are one of my favourite CC features, and have greatly improved my asset management.  Being able to create a library for each client that has fonts, colour swatch, Smart Objects etc. has been a huge time saver.  It means things are always there and available, and can be dragged onto a document window to retrieve them.  I LOVE CC Libraries.

As Bojan said back up the thread, Bridge is an excellent resource, and can be used for more than simple DAM (Digital Asset Management) to keep track of your pictures.  I store image sets with date and meaningful name so they list in order

I like that Bridge lets up give images a star rating, which lets me sort them into 'keepers, trash, good enough to upload'.

Bridge also has some very hand scripted features/tools.  Load Files into Photoshop Layers, for instance.  I use that one a lot.

Would you like to have this moved to the Photoshop forum where other Photoshop users read?

One way is using Window > Libraries and the second way I am using is Bridge keyword + collections.
