What is an .SRF file?

.SRF is Server Response File

File used by Visual Studio .NET applications and processed by the ATL Server engine; may contain both static HTML and script tags that produce dynamically generated content when the page is loaded.

The file "login.srf" is commonly used by secure websites. It processes the user's username and password, sends a cookie identifying the user back to the browser, and redirects the user to the secure page.

An SRF page may also be called a "stencil" since it may contain tags that can be processed by CHtmlStencil.

File Type 5 Smaart Spectrum File
Developer by: Rational Acoustics Category: Data Files

An SRF file is a data file created by Rational Acoustics Smaart, a program used by audio technicians and engineers to measure and analyze the acoustics of an environment. It contains a static "snapshot" of live spectrum measurements, which consist of a measurement signal (the output from a device) and an input signal used for reference. SRF files also store spectrum settings, such as the frequency scale of the graph, slice height of the spectrograph, and RTA display settings.

SRF file open in Rational Acoustics Smaart v8

Spectrum measurements allow users to analyze one or more input channels. The measurements are displayed as a graph in real-time. These graphs can be captured by selecting Capture or Capture All in the Data bar in the "Spectrum" view. Captured spectrum measurements are saved in the SRF file.

By default, SRF files are placed in the following directory:

Documents\Smaart v8\Traces\Spectrum\Session Data

You can move them from this location. However, the spectrum measurements stored in the SRF files that are moved will no longer be displayed in Smaart.

Rational Acoustics Smaart enables audio technicians to analyze sound systems and diagnose problems. It is used in a variety of venues, such as stadiums, concert halls, and churches. The name of the program is an acronym, which stands for System Measurement Acoustic Analysis Real-time Tool (SMAART).

NOTE: SRF files were introduced with version 8 of Smaart and replaced REF files used by earlier versions of Smaart.

File Type 7 Samsung Smart TV Recording File
Developer by: Samsung Category: Encoded Files

An SRF file is a video recording file created by select Samsung Smart TVs. It contains content, such as a TV show or movie, recorded on the TV. SRF files are encrypted and can only be opened by the Samsung Smart TV that created them.

Samsung Smart TVs are used by some users as personal video recorders (PVRs) to record digital video to a USB flash drive. The TVs encrypt SRF files because of digital rights management (DRM) issues in order to protect against illegal sharing of recorded content from the TV.

How to solve problems with SRF files

  • Associate the SRF file extension with the correct application. On :
    Windows: Right click on any SRF file and then click "Open with" > "Choose another app". Now select another program and check the box "Always use this app to open *.SRF files". Mac: Right click (or Ctrl-click) the SRF file, then click "Open with" > "Other...". Then choose another program and check the "Always Open With" box. Linux: Right click on the file, and select "Open with" and choose another program. iPhone: Tap the file. If you do not see an app to open the file, then tap Share "Share" and choose an app. Alternatively, save the file.

Then tap "Share" and select an app. Android: Tap the Settings icon on your smartphone, then tap on the Apps section. There tap the Options icon in the top right-hand corner of the screen to change the default apps.
  • Update your software that should actually open .SRF is Server Response File. Because only the current version supports the latest SRF file format. Search, therefore, e.g. on the Microsoft manufacturer website after an available .SRF is Server Response File update.
  • To make sure that your SRF file is not corrupted or virus-infected, get the file again and scan it with antivirus software.
