Unlike its installed counterpart, this portable version runs directly from a USB flash drive, external HDD, or even a cloud folder. No registry entries. No leftover files. Just pure, high-performance screen capture wherever you go. ZD Soft Screen Recorder is a well-known Windows application famous for its high-performance game recording, smooth desktop capture, and low system overhead . The Portable variant offers the same engine but in a self-contained executable.

In that case, look at OBS Studio (free but not truly portable) or Loom (web-based but requires login).

Extract the folder to your USB drive or a local directory like D:\PortableApps\ZDScreenRecorder .

Enter .

A: Yes, it uses WASAPI loopback, which captures system audio even if your sound card lacks “Stereo Mix.”
