What is an ALR file?

ALR files mostly belong to Text Editor. ALR files have different uses depending on where they come from. They are not a single standard format but serve specific roles across systems.

Automation System Alarm Log: These files record alarm events from automation systems. They are often encoded in UTF-16 (LE) to capture detailed log information.
Emergency Alert File: In some cases, an ALR file is used to store alert notifications. This version is generated by systems like the Comlabs EAS Alert Generator and follows an alert notification file format. For additional information, visit Comlabs.
Digital Regulator Alarm Log: Another type logs alarm data for digital regulators, such as those used in the MECC ALTE DSR/DER1 systems. More details can be found at MECC ALTE.
Resident Evil 4 Archive: Some ALR files are used as archive files in gaming, connected with the Psion Series 5 File Format and CRI Middleware's CRI ADX2. This variant stores game data in an archival package.

FilExt.com note: Depending on the variant, you may open an ALR file with a text editor (if it is a log file) or with specialized software provided by the system vendor or game developers.
