What is an ESW file?

ESW files mostly belong to Carlson Survey. The ESW file extension is used by different software tools for storing distinct types of information.
In one case, an ESW file is an earthwork file format. It holds data on grading, excavation, and 3D modeling for surveying and construction projects. You can work with these files using the specialized software from Carlson Survey available on their website.
In another case, an ESW file is a SAPscript text file encoded in UTF-16 (LE). This version is used in SAP environments for form layout and text processing. Applications like Able2Extract Professional from Investintech (see their website) handle this type of file.
A further use sees the ESW extension applied to embroidery design files. These files store pattern and stitch data, which is useful for machine embroidery. Users can open them with embroidery software such as EmbroideryStudio offered by EasySign (learn more here).
