📁 Caustic Folder Icon Manager

Give your Caustic 3 installation a clean, personalised visual identity.

Caustic 3’s standalone Windows installation uses standard folder icons throughout its directory structure. Caustic Folder Icon Manager is a portable utility that replaces those plain folders with custom .ico files using mix‑and‑match icon profiles.

Independently customize your App, Preset, and Skin folders; preview your layout before applying changes; and push the final configuration directly into Windows — creating a more cohesive, expressive Caustic environment on your desktop.

🎨 Why This Tool Exists

Caustic 3 has a strong visual identity inside the app, but its standalone Windows installation sits inside a set of plain, generic folders. Nothing around it reflects the character or personality of Caustic itself.

Caustic Folder Icon Manager was built to bridge that gap.

Instead of modifying Caustic’s interface or touching the application files, the utility enhances the Windows side of the experience—giving the surrounding folders their own distinct look and feel.

The result is a more unified, expressive Caustic environment on your desktop, rather than a collection of ordinary Windows directories. It brings a bit of Caustic 3 creative energy into the places you navigate every day.

⭐ Key Features

Live Preview Mode — Instantly switch between your current folder icons (Before) and a live preview of the proposed configuration (After) before applying anything.
Dry Run Report — Scan the Caustic directory structure and see exactly which folders have matching icons, with [OK] and [NO ICON] results before making changes.
Mix-and-Match Profiles — Choose separate icon profiles for App, Presets, and Skins, allowing different visual themes to be combined however you like.
Apply Icons — Generates the required Windows desktop.ini configurations and assigns the selected .ico files to the matching folders.
Reversible — Remove the custom icon settings managed by Folder Icon Manager with Reset to Default, returning those folders to the normal Windows appearance.
100% Portable — No installation is required. Settings and icon profiles can be kept alongside the application, allowing the utility to be moved between PCs or run from removable media.

🖥️ How It Works

Folder Icon Manager organises icon selection into three independent categories:

App — Customises the main Caustic application and core document directories.
Presets — Customises machine preset folders and their associated subfolders.
Skins — Customises directories containing Caustic visual themes.

Each category can use a different icon profile, allowing you to create your own combination without having to modify the icon packs themselves.

Nothing is applied while you experiment with profiles. Change the app, preset, and skin selections and use the before/after preview to see the proposed result before choosing apply icons.

Quick-Start Steps

Open Folder Icon Manager and select your Caustic 3 installation folder.
Select your preferred icon profiles for App, Presets, and Skins.
Use Preview Mode to inspect the proposed changes in the folder tree.
Run a dry run to check that the required folder names have matching icons.
Click Apply Icons to write the Windows folder-icon configuration.
Refresh Windows Explorer if necessary to see the changes immediately.

⚠ Reset to Default

Reset to Default removes the custom folder-icon settings managed by Folder Icon Manager and returns those folders to the normal Windows appearance. It is not a backup and restore system. If a different custom desktop.ini configuration existed before using Folder Icon Manager, the application does not preserve or reconstruct that previous configuration.

Note: The icon operation itself does not modify your Caustic application files, presets, songs, samples, or other music data.

🔧 Explorer Tools & Troubleshooting

Windows caches folder icons, which can sometimes prevent newly applied .ico files from appearing immediately. Folder Icon Manager includes several tools to help with this:

Refresh Explorer: Refreshes Windows Explorer to encourage the new folder icons to appear.
Restart Explorer: Restarts the Windows Explorer process when a normal refresh isn't enough.
Force Icon Cache Refresh: Performs a more thorough Windows icon-cache refresh. This closes open Explorer windows and temporarily restarts the desktop environment.

If an icon still doesn't appear after applying a profile, the Dry Run report can also help identify missing or incorrectly named .ico files.

📦 Building Custom Icon Packs

Folder Icon Manager uses a simple directory structure so that anyone can create and share their own icon profiles.

📁 Folder Structure

To create a custom profile, organise your .ico files inside these three subfolders:

📁YourProfileName/

├── 📁 App_icons/

├── 📁 preset_icons/

└── 📁 skins_icons/

File Naming & Inheritance

Filename Matching: Icons are matched to folder names case-insensitively, while the rest of the filename must match exactly. For example, app.ico is used for the app folder and documents.ico for the documents folder.
Preset Machine Icons: Machine folders such as pcmsynth, subsynth, and beatbox can have their own icon.
Machine Inheritance: Subfolders beneath a machine preset directory inherit the machine's icon, so an individual .ico file isn't required for every nested folder.
Missing Icons: If a matching icon cannot be found, the Dry Run report identifies the folder as [NO ICON] rather than silently applying something else.

🤝 Community & Contributions

Folder Icon Manager was created to give Caustic 3 a little extra character on Windows while making it easy for the community to create and exchange folder icon sets.

Share Icon Packs: Create your own profile and share it with the Caustic community on Reddit at r/Caustic.
Create Your Own Designs: Profiles can be built around different Caustic machines, visual styles, colours, themes, or personal preferences.
Report Issues & Ideas: Found a problem, have a suggestion, or would like support for another Caustic folder structure? Feedback and community ideas are always welcome.

⚠️Disclaimer

This is an independent, fan-made tool and is not affiliated with, endorsed by, or associated with Single Cell Software or Caustic in any way. "Caustic" is referenced only to describe what this tool works with.

This app modifies real files and settings on your system — it writes desktop.ini files, changes folder attributes (read-only, hidden, system), and can trigger a full Windows icon cache rebuild that briefly restarts Explorer.

It's built with safeguards (dry run previews, confirmation prompts, and a Reset to Default option), but it's provided as-is, with no warranty of any kind. Use it at your own risk, and consider backing up your Caustic folder before applying changes if you want extra peace of mind.
