Tekla Structures uses the information in the message files to display messages in the user interface. Message files include, for example, texts used in dialog boxes.

• Message files with the .ail extension are located in the folder ..\Tekla Structures\<version>\messages.

• Message files with the .xml extension are located in the folder ..\Tekla Structures\<version>\messages\DotAppsStrings.

The files include texts in languages in which the Tekla Structures user interface is available.
