1. Hi Copilot , is there a file transfer software from one Thunderbolt 4 port to another Thunderbolt 4 port which come with the Thunderbolt 4 cable just like we use to have a file transfer software to transfer files from one USB port to another USB port ? Copilot , i have a USB to USB file transfer cable which is manufactured by TARGUS Company , and i believe there should be a smilar cable like that for the Thunderbolt 4 port whereby we can transfer files from one Thunderbolt 4 port to another Thunderbolt 4 , ONLY THIS TIME I BELIEVE THE FILE TRANSEFER SPEED SHOULD BE EXTREMELY FAST DUE TO THE THUNDERBOLT 4 TECHNOLOGY ! Copilot , could you please shed some light on this interesting topic . THANKS for the answer.

Yes, Norizan — there is now a Thunderbolt‑specific solution called Thunderbolt™ Share that works very much like your old Targus USB‑to‑USB transfer cable, but at Thunderbolt 4/5 speeds. It lets you connect two PCs directly with a Thunderbolt cable and transfer files, share peripherals, or even migrate entire systems at up to 20–40 Gbps.

⚡ What Thunderbolt™ Share Offers

Direct PC‑to‑PC transfers Connect two Windows PCs with a Thunderbolt 4/5 cable and move files instantly — no external drives or cloud needed.
Ultra‑fast speeds Up to 20 Gbps with Thunderbolt 4 and 40 Gbps with Thunderbolt 5, far beyond USB transfer cables.
System migration Built‑in wizard to copy files/settings from an old PC to a new one.
Peripheral sharing Use one keyboard, mouse, and monitor across two PCs — like a KVM switch but simpler.
Secure connection Peer‑to‑peer PCIe tunnel with Intel VT‑d protections, bypassing Wi‑Fi or Ethernet.

🔌 How It Compares to USB Transfer Cables

Feature	USB Transfer Cable (Targus)	Thunderbolt™ Share
Speed	~480 Mbps (USB 2.0) / ~5 Gbps (USB 3.0)	20–40 Gbps (Thunderbolt 4/5)
Software	Proprietary transfer utility	Intel Thunderbolt™ Share
Use Case	Basic file copy between PCs	File transfer, migration, peripheral sharing, multi‑PC workflows
Cable	Special USB transfer cable	Standard Thunderbolt 4/5 cable
OS Support	Windows (older versions)	Windows 11 PCs with Thunderbolt 4/5

⚠️ Things to Keep in Mind

Licensed hardware required: At least one PC or accessory must be Thunderbolt Share‑enabled.
Windows 11 only: Official support is for Windows 11 PCs with Thunderbolt 4/5 ports.
Availability: Thunderbolt Share is bundled with certain Intel‑certified PCs and accessories; check if your laptop/desktop supports it.
Cable type: You don’t need a special “transfer cable” — a standard Thunderbolt 4 cable works.

✅ Bottom Line

If you loved your Targus USB transfer cable, Thunderbolt™ Share is the modern, high‑speed equivalent — but far more powerful. With Thunderbolt 4/5, you can expect extremely fast transfers, seamless PC migration, and even shared peripherals over a single cable.

Would you like me to show you which Thunderbolt 4 laptops and accessories available in Malaysia already support Thunderbolt™ Share so you can try this out locally?

2. Copilot , could you please sketch for me how a standard Thunderbolt 4 cable looks like and Copilot could you please link me to a dedicated website whereby someone did a review on this Thunderbolt 4 cable "file transer speed " in action , meaning , someone connect a Thunderbolt 4 cable from one end to another end to a Windows 11 PC/Desktop or a Windows 11 Laptop with the "file transfer speed" meter showing the speed of the data transfer. THANKS Copilot for the answer.

Here’s a sketch of a standard Thunderbolt 4 cable — it looks like a regular USB‑C cable but with the Thunderbolt lightning logo and the number “4” printed on the connector housing. For real‑world speed tests, reviewers have demonstrated Thunderbolt 4 cables sustaining up to 40 Gbps file transfers between Windows 11 PCs and laptops.

🔌 Thunderbolt 4 Cable Design

Connector type: USB‑C (reversible, slim oval tip).
Logo: White lightning bolt with a “4” beneath it.
Cable thickness: Slightly thicker than standard USB‑C for shielding and signal integrity.
Length options: Passive cables up to 0.8 m (full 40 Gbps), active cables up to 2–3 m with retimer chips.
Power delivery: Up to 100 W (standard) or 240 W (Extended Power Range).

⚡ File Transfer Speed in Action

Several reviewers have tested Thunderbolt 4 cables with external SSDs and PC‑to‑PC transfers, showing real throughput near 40 Gbps (about 5 GB/s). That’s dramatically faster than USB 3.0 (~5 Gbps) or even USB 3.2 (~20 Gbps).

Thewearify Review: A detailed breakdown of Thunderbolt 4 cables, including actual transfer speed tests with Windows laptops and SSDs, showing how passive vs. active designs affect performance .
WellWhisk Review: Compares Thunderbolt 4 vs. USB4 Gen4 cables, with benchmarks moving multi‑gigabyte video files in seconds .
Thewearify Extended Review: Explains how active Thunderbolt 4 cables maintain full 40 Gbps over 2 m lengths, with screenshots of speed meters during transfers .

📊 Comparison Table

Cable Type	Max Speed	Length Limit	Power Delivery	Best Use Case
Passive Thunderbolt 4	40 Gbps	≤0.8 m	100 W	Short, ultra‑fast SSD or PC transfers
Active Thunderbolt 4	40 Gbps	2–3 m	100–240 W	Longer runs, workstation setups
USB4 Gen4	80 Gbps	1–2 m	240 W	Extreme video editing, multi‑8K displays

⚠️ Things to Watch Out For

Lookalike cables: Many USB‑C cables look identical but don’t support Thunderbolt speeds. Always check for the Thunderbolt logo + “4”.
Device support: Both PCs must have Thunderbolt 4 ports; otherwise, speeds fall back to USB levels.
Active vs. passive: For longer cables, only active designs sustain full speed.

✅ Bottom line: A certified Thunderbolt 4 cable gives you up to 40 Gbps file transfer speeds between Windows 11 PCs — reviewers confirm this with speed meters in real tests. If you want to replicate your Targus USB transfer cable experience but at extreme speeds, Thunderbolt 4 with Intel’s Thunderbolt™ Share software is the modern solution.

Would you like me to link you directly to Malaysia‑based retailers that sell certified Thunderbolt 4 cables, so you can try these high‑speed transfers yourself?
