What is stm file?

The web file with the stm file extension instead the more common htm file extension indicates a file that includes some information that will be added "on the fly" by the server before it is sent to you. A typical use is to include a "Last modified" date at the bottom of the page.

This Hypertext Transfer Protocol facility is referred to as a server-side include. (Although rarely done, the server administrator can identify some other file name suffix than "shtml" as a server-side include file.)

You can think of a server-side include as a limited form of common gateway interface application. In fact, the CGI is not used. The server simply searches the server-side include file for CGI environment variables, and inserts the variable information in the places in the file where the "include" statements have been inserted.

When creating a Web site, a good idea is to ask your server administrator which environment variables can be used and whether the administrator can arrange to set the server up so that these can be handled. Your server administrator should usually be able to help you insert the necessary include statements in an html file.

NanoEducator data

File type category:
Various data file

Date updated: October 5, 2026

Record marked as obsolete and not updated for a long time.

NanoEducator is an educational scanning probe microscopy system developed by NT-MDT for teaching and training in scientific laboratories. Its software uses stm files to store data associated with the system.

The exact contents depend on the NanoEducator operation that created the file, but the file is intended for use within the NanoEducator environment rather than as a general-purpose data document.

The format is obsolete and is no longer commonly used in current software. Existing files may therefore require the original NanoEducator software or an installation supplied with the associated laboratory equipment.

How to open stm file?

Open the stm file with the original NanoEducator software. Because the format is obsolete, a current general-purpose application may not recognise it.

If the original software is unavailable, contact the laboratory or equipment supplier that created the file. Keep an untouched copy before attempting to open or modify it.

How to convert stm file?

There is no widely established standalone converter for the NanoEducator stm format. If the file opens in NanoEducator, use that software's available export or save options to create a more accessible copy.

Without the original software, reliable conversion is generally not possible because the file's contents and structure are specific to the NanoEducator system.
