An ".AM" file doesn’t inherently describe its contents because extensions aren’t controlled globally and developers reuse them freely, meaning .am files may be plain-text build configs, scientific/3D-visualization data sets, or older multimedia project files, while Windows’ file associations can further blur things by choosing an opener without checking the real data, and the most common developer-facing version is "Makefile.am," an Automake template listing variables such as bin_PROGRAMS which get transformed into Makefile.in and eventually a Makefile for `make` to build the project.
Other uses may also surface, such as Amira/Avizo AmiraMesh visualization data with readable headers and binary payloads, or legacy Anark Media files from older multimedia systems that appear mostly binary in a text viewer, and the simplest identification method is checking context and content—if the text is readable and build-like it’s likely Automake, if it contains scientific header info referencing mesh/data segments it’s probably AmiraMesh, and if it’s mostly unreadable it’s a binary format—while a tool like the `file` command provides one of the most dependable confirmations by analyzing real bytes instead of trusting the extension.
The reason the `file` command is regarded as reliable is that it bypasses extensions entirely and analyzes real byte content, comparing it to known signatures or *magic numbers* plus structural hints, as many formats start with recognizable patterns, and even without those, it can tell whether a file looks like text, structured markup, scripts, compressed material, executables, or binary blobs, which is particularly helpful for `.am` files because it shows what the data actually resembles instead of depending on Windows’ association rules.
In practice, when an `.am` is an Automake template, `file` often tags it as readable text, occasionally even labeling it as a makefile, while scientific or media-related `.am` formats tend to be recognized as binary, data, or a specific type if a known signature matches, and this becomes useful for catching mislabeled files—such as `.

To identify an .AM file type quickly, rely on context and a light content check since the extension spans entirely different use cases, so if your file is `Makefile.am` inside a source folder with items like `configure.ac`, `configure.in`, `aclocal.m4`, or multiple Automake files, it’s a GNU Automake template rather than a document, but names such as `model.am` or `scan.am` from research or CAD environments usually indicate an AmiraMesh file, marked by a readable header detailing mesh or grid attributes and a large section that mixes readable text with binary data.
If the file comes from an older interactive presentation setup and doesn’t resemble code or scientific metadata, there’s a good chance it’s an Anark Media file, which looks binary and unreadable in Notepad, and that simple test helps sort things out: clean build-style text points to Automake, structured technical headers suggest scientific visualization, and mostly unreadable characters indicate a binary data/media format, with template files staying tiny while data-heavy ones grow large, though the most reliable clue is where the file came from and what the opening lines show.
