Introduction

Welcome to CBFS Sync, a suite of classes enabling seamless synchronization between local files and Cloud Storage or other remote repositories.

Add OneDrive-style, bi-directional synchronization to your applications with CBFS Sync. The event-driven design of CBFS Sync provides an intuitive way to handle operations performed on local files and folders. When remote changes are made, use the included methods to notify the local system.

The CBSync class builds on industry-standard technologies, including the Cloud Filter API on Windows, FUSE on Linux, and File Provider on macOS. CBSync reduces development time and improves user experience by providing a single API. All icons and indicators visible to the user are presented by the operating system, ensuring a native experience.

The choice of the remote storage location is entirely up to you. Whether your data is stored on a popular cloud storage service, a custom file server, or anywhere else, CBFS Sync provides a simple API to facilitate synchronization. CBFS Sync handles integration with the OS, while your code is responsible for responding to events and transferring data between local and remote systems. Because your code interacts with the backend, you can also decide to make the synchronization one-way or bidirectional.

Deployment

The user-mode library comes in It has one or two forms depending on the platform:

• Dynamic:
  • Windows: As dynamic libraries with import libraries, named cbfssync22.dll and cbfssync22.lib, respectively (available for x64, ARM64, and x86 processor architectures)
  • Linux: As dynamic libraries, named libcbfssync.so.22.0 (available for x64 and x86 processor architectures)
  • macOS: As dynamic libraries, named libcbfssync22.0.dylib (available for x64 and ARM64 processor architectures)
• Static:
  • Windows: As static libraries, which do not require a dynamic library, named cbfssync22s.lib.

Windows:

Use the DLL with the import library if incompatibilities occur between the compilation and linkage options set in your project and the options with which the library was compiled.

When linking the static library, no extra user-mode library files need to be deployed with the application. When using the DLL, deploy the .dll file to the target system and place it next to the application's .exe file.

Note: When linking the static library, the Windows library version.lib must be included in the linker options.

Linux:

To link the CBSync class to your application and use them properly, the FUSE 2.9 package must be installed in your development system. This can be achieved using the following commands:

• RedHat/CentOS and derivative Linux distributions: sudo yum install fuse-devel
• Debian/Ubuntu and derivative Linux distributions: sudo apt-get install libfuse-dev

FUSE 2 must be installed in target systems, where your application is deployed. Modern versions of Linux do not include FUSE 2 by default, but it can be installed using these commands:

• RedHat/CentOS and derivative Linux distributions: sudo yum install fuse-libs
• Debian/Ubuntu and derivative Linux distributions: sudo apt-get install libfuse2

Constants

All constants are accessible through the cbyConstants namespace declared in the cbfssync.h file.
