+# DirectoryScanSender
+
+`DirectoryScanSender` is a .NET application that scans a directory recursively and sends eligible files to a TCP server using a simple delimiter-based protocol.
+
+It is the sender counterpart to [`DirectoryScanReceiver`](../DirectoryScanReceiver), and both projects can work together out of the box with the current default settings.
+
+## Companion Project
+
+- Receiver counterpart: [`DirectoryScanReceiver`](../DirectoryScanReceiver)
+- Shared default TCP port: `7156`
+
+## Shared Protocol
+
+Both projects use the same message format:
+
+```text
+<path>|<length>|<content>\r\n\r\n
+```
+
+- `path`: file path string sent by the sender
+- `length`: declared payload length
+- `content`: payload content
+
+Multiple messages can be sent over the same TCP connection, each terminated by `\r\n\r\n`.
+
+## Features
+
+- Recursively scans directories
+- Sends files over a single TCP connection
+- Skips files larger than `100000` bytes
+- Continues running even if individual files fail to read or send
+- Uses parallel directory traversal
+
+## Default Behavior
+
+- Target directory: the current user's `Documents` folder
+- Connection target: host `localhost`, port `7156`
+- File size limit: files smaller than `100000` bytes
+
+## Requirements
+
+- .NET SDK with support for `net10.0`
+- Network access to the configured TCP server
+
+## Build and Run
+
+From the repository root:
+
+```bash
+dotnet build
+dotnet run --project DirectoryScanSender
+```
+
+## Compatibility Notes
+
+- The sender is intended to be used with [`DirectoryScanReceiver`](../DirectoryScanReceiver) or another receiver that follows the same message format.
+- The current defaults (`localhost:7156`) match the local `DirectoryScanReceiver` project.
+- The transfer uses plain TCP and does not include authentication or encryption.
+- Console output is used for basic status and error messages.
+- Configuration values (host, port, scan path) are defined in `DirectoryScanSender/Program.cs`.
