An “.AM” file isn’t reserved for one purpose because extensions aren’t globally controlled and different developers can freely choose them, so unrelated software may all use “.am” for different things, leading to cases where one .am file is a text-based build config, another is scientific or 3D-visualization data, and another is an older multimedia project, with Windows sometimes adding confusion by assigning an opener based on associations instead of real content, while the most common developer version is “Makefile.am,” an Automake template containing human-readable variables like *_SOURCES that describe how a project should be built before Automake and `configure` turn it into the final Makefile used by `make`.
Other uses may show up as well, including Amira/Avizo AmiraMesh files used in scientific visualization, which tend to have readable headers and sometimes binary data, or old Anark Media formats from interactive multimedia tools that look largely binary when viewed as text, and the simplest way to identify your .am file is by checking its context and contents—build-like readable text leans toward Automake, structured scientific headers or mesh references toward AmiraMesh, and mostly garbled symbols toward a binary media format—while a byte-level tool like the content-sniffing `file` often provides the most reliable confirmation.
The reason the `file` command stands out in reliability is that it ignores the extension completely and examines raw bytes, matching them against known signatures or *magic numbers* plus structural clues, as many file types begin with unique headers, and even those without them can be identified by whether the content resembles plain text, markup-like text, scripts, compressed chunks, executables, or binary blobs, which is especially useful for `.am` files since `file` reports what the data truly resembles rather than relying on Windows’ association guess.
In practice, if your `.am` is an Automake file, `file` usually identifies it as ASCII/Unicode text, sometimes labeling it a makefile, whereas media/scientific `.am` files are usually recognized as binary/data or as a specific format when signatures match, and this also uncovers mislabeled `.am` files—like those that turn out to be ZIP or gzip archives—since renaming errors are common, with Linux/macOS running `file yourfile.am` and Windows leveraging Git Bash, WSL, Cygwin, or GnuWin32 to get output that generally reveals which workflow it belongs to and whether it should be opened as text or treated as binary.
To identify what type of .AM file you’re dealing with, the most efficient approach is combining context clues with a quick content check, because “.am” spans very different domains, and if the file is `Makefile.am` inside a source tree containing things like `configure.ac`, `configure.in`, or `aclocal.m4`, it strongly signals GNU Automake build templates, whereas names like `model.am` or `dataset.am` from research or 3D visualization pipelines typically indicate AmiraMesh, which shows a readable metadata header and a mixed binary/text data section.

If the file was created by older interactive media software and doesn’t look like code or scientific metadata, it might be an Anark Media file—these read as unreadable binary in Notepad—and the quick text-editor test works well: readable build-oriented text points to Automake, structured metadata suggests scientific visualization, and immediate gibberish signals a binary media format, with file size helping only slightly, while the strongest indicator is its origin and what appears in the first few lines.
