File-Tunnel is a tunneling tool that moves TCP connections through a shared file or file server. It is built around the unusual idea that two systems can exchange network data by reading and writing files that both sides can access. This makes it useful in environments where direct TCP connectivity is blocked but a shared folder, FTP server, S3-compatible storage, Dropbox folder, RDP drive share, or similar file channel is available. The project provides portable executables for Windows, Linux, and macOS, which makes it practical for cross-platform testing. Its documentation includes examples for bypassing firewall limitations, tunneling through FTP, using remote internet access, and routing through remote desktop file shares. File-Tunnel is best understood as a specialized connectivity workaround for controlled environments where file access exists but normal network routing does not.
