What is a MAL file?

MAL files mostly belong to Topcon Magnet Field. This MAL file can serve multiple functions.: If the file comes from surveying data, it represents data captured by Topcon instruments. These files are produced by Topcon Magnet Field software and Topcon Tools and are used to record field measurements. They are similar to Trimble survey files and files from MicroSurvey STARNET. For more details on surveying tools, visit Topcon Positioning.
If the MAL file is in a Windows executable format (EXE), it has been renamed and might be used to hide potentially malicious software. In this case, you should scan the file with antivirus software and verify it using resources such as VirusTotal.
Another use is as a Machine Alarms file. In this variant, the file uses a Microsoft Compound format and is similar to a Microsoft Access lock file. It stores log or alarm data from machines.
Usage tips:
  • Check the file source to decide which application should open it.
  • If it is survey data, use Topcon or MicroSurvey software.
  • If it appears as a Windows executable, treat it with caution and scan it first.
  • If it is a machine alarm file, use the relevant Microsoft or industrial system tools.
  • How to open MAL files
