Convert a file to ATH
To convert other file formats to the "Cost Estimation & Lighting" file type, you need software like Athenasoft Norma or a similar tool.
About ATH files
The .ath extension typically refers to a Construction Cost Estimate created by Athenasoft Norma software (including Norma PRO and Norma STANDARD). These files contain detailed project budgets, material lists, and labor calculations commonly used in the Polish construction industry. The main limitation with .ath files is their proprietary nature; they are binary containers that require expensive, specialized licensing just to view the line items. You cannot simply open them in Microsoft Excel or a web browser, making collaboration with clients or contractors difficult without converting the data first. For sharing estimates, the best practice is converting to PDF to preserve formatting, or XLSX / CSV if you need to manipulate the figures in a spreadsheet.
Alternatively, if you are a gamer, your .ath file might be an AlienFX Lighting Theme used by the Alienware Command Center. These are often formatted as XML files that control LED lighting zones on Dell hardware. While less opaque than the Athenasoft format, older AlienFX themes often suffer from compatibility issues with newer hardware drivers. Converting these to plain TXT or XML allows you to inspect the color codes and scripts manually to troubleshoot lighting errors or migrate profiles.
Convert.Guru analyzes your ATH file, detects the exact format, and lets you read the text inside.
If you want to convert ATH file to PKR, ATM, GEM, INI, CFG, CONF, CONFIG, JSON, XML, YAML, YML or TOML, you can use Athenasoft Norma or similar software from the "Construction Cost Estimation" category. In the File menu, look for Save As… or Export….
To convert ZSHRC, CONF, RCFILE, GITCONFIG, RC, PLIST, BASHRC, CONFIG, PROFILE, INI, PREFS or CFG files to ATH, try Athenasoft Norma or another comparable tool in the "Construction Cost Estimation" category.
The ATH Converter Story
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our ATH converter.
