Release Notes
Bugfixes
- Capture files cannot be saved to network drives.
Runtime Requirements
- .NET 9 is now required for full feature support and optimal stability. Download here.
CapFrameX Portable Mode
CapFrameX now supports a portable mode that allows the application to run entirely from a single folder without writing to system directories. This is useful for running from USB drives, network shares, or keeping multiple isolated installations.
How It Works
Portable mode is activated by placing a portable.json file in the same directory as the CapFrameX executable. When the application starts, it checks for this file and redirects all data storage to paths relative to the application directory.
Key Features
- Self-contained: All configuration, captures, screenshots, and logs are stored relative to the application folder
- No registry modifications: The application doesn't write to the Windows registry in portable mode
- No system folder usage: Bypasses %AppData% and Documents folders entirely
- Configurable paths: All storage paths can be customized via portable.json
portable.json Configuration
Create a portable.json file in the CapFrameX application directory with the following structure:
{
"portable": true,
"paths": {
"config": "./Portable/Config",
"captures": "./Portable/Captures",
"screenshots": "./Portable/Screenshots",
"logs": "./Portable/Logs",
"cloud": "./Portable/Captures/Cloud"
}
}

─────────────────┼────────────────────────────────────────────────────────────────────────────────┼─────────────────────────
paths.cloud │Cloud download directory │./Portable/Captures/Cloud
─────────────────┴────────────────────────────────────────────────────────────────────────────────┴─────────────────────────
All paths are relative to the application directory. You can use ./ or .\ prefix, or just the folder name.
Requirements
When running in portable mode, the following dependencies must be installed on the system:
- .NET 9.0 Desktop Runtime (x64) - Download
- Visual C++ 2015-2022 Redistributable (x64) - Download
The application will check for these dependencies on startup and display a message if any are missing.
Creating a Portable Distribution
1. Copy the CapFrameX application files to a folder
2. Create a portable.json file with the configuration above
3. (Optional) Pre-create the Portable subdirectory with: Config, Captures, Screenshots, Logs
4. The application is now portable and can be moved to any location
