TKR-Drop brings seamless, drag-and-drop file transfers between Windows computers on your local Wi-Fi or Ethernet network. No internet upload, no cloud size limits, and 100% cryptographic SHA-256 verification.
Uploads your files over the internet to a third-party server, waits for processing, and forces the recipient to re-download. A 10GB file can take over an hour and burns internet data.
Transfers directly computer-to-computer over your local Wi-Fi router or switch. A 10GB file transfers in approximately 90 seconds with zero internet consumption.
Incoming files stream into isolated temporary .part buffers. The final file is committed to your Downloads folder only when all bytes arrive intact. If connection drops, incomplete files never corrupt existing data.
Both sender and receiver compute end-to-end SHA-256 hashes during transit. After byte delivery, cryptographic digests are compared before the receiver issues a signed ACK receipt. Bit-for-bit exact copy guaranteed.
Never lose existing files. If a file named Project.zip already exists on the receiving machine, TKR-Drop automatically stages the incoming transfer as Project (1).zip cleanly.
Strict security policies block path traversal attempts (e.g. ../../System32/), absolute path overrides, and unauthorized system folder writes. Files land strictly in your authorized intake folder.
Drop entire folders containing thousands of subdirectories, source code files, or photo libraries. TKR-Drop recursively builds the directory tree on the receiving end without manual zip packaging.
Instant peer discovery over UDP multicast and BLE. Just open TKR-Drop on two laptops on the same Wi-Fi, and they appear instantly with friendly machine names.

Yes! TKR-Drop is packaged as a lightweight, 100% standalone single-file executable. Just download TKRDesk-Drop.exe and run it directly. No installation or registry keys required.
Yes. TKR-Drop operates exclusively on your local Wi-Fi or LAN network. Even if your ISP cable is unplugged or you are connected to a mobile phone Wi-Fi hotspot without internet, transfers proceed at wire speed.
Windows Nearby Sharing frequently fails between different Windows editions (Home vs. Pro), requires Microsoft Account logins, and struggles with large folders. TKR-Drop connects instantly via P2P and handles 50GB+ payloads without failure.
Every build is Authenticode digitally signed and cataloged with a public SHA-256 cryptographic digest. Run Get-FileHash TKRDesk-Drop.exe in PowerShell and compare it with the published hash table.
