The AVX format was used by ArcView GIS, a desktop geographic information system developed by Esri for Microsoft Windows. An AVX file contains an ArcView extension that provides added functionality.
Extensions integrate with ArcView rather than serving as standalone documents. They can add features to the program, including tools or support not included in the standard installation. The format is associated with the legacy Windows version of ArcView and is not a general-purpose data exchange format.
Open or load an .avx file with ArcView GIS on Microsoft Windows. Install or copy the extension where ArcView can find it, then enable it through ArcView's Extensions dialog.
An AVX file is a plugin, so it normally cannot be opened as a document or used meaningfully without a compatible ArcView installation. It may also be usable with other compatible Esri programs.
AVX extension plugins are software components, not documents or datasets, so conversion to another file format is generally highly unlikely.
If the extension is needed in another environment, a compatible version of the plugin is required. Converting the AVX file does not turn its functionality into a standalone ArcView project or data file.
