What is an ESX file?
The .ESX file extension usually represents a Wi-Fi site survey project created by Ekahau Site Survey. These files store floor plans, access point configurations, and signal heatmaps. Network engineers use them to design and optimize wireless networks. Internally, Ekahau .ESX files are compressed ZIP archives that bundle XML data and images.
Because developers can reuse file extensions, an .ESX file might also be an Eye examination data file exported by Haag-Streit EyeSuite software (formatted as XML data). It could also be a sampler audio file for a Korg Electribe synthesizer, or an Xactimate Insurance Claims Estimate used by Xactware software to process property damage reports.
How to open ESX files?
To view and edit these files fully, you need the original software. You open survey files with Ekahau AI Pro and insurance estimates with Xactimate. If you only need to inspect the raw data of an Ekahau project, you can change the file extension from .ESX to .ZIP and extract it with an archive tool like 7-Zip.
View ESX files online
viewer.online/esx analyzes .ESX files to identify their exact format and creator software, shows which programs can open the file, and usually previews it. Because the .ESX extension has multiple possible meanings, we recommend using viewer.online/esx to identify the actual format of your specific file.
Summary
Because the most common .ESX files use the known ZIP format, viewer.online/esx can safely open and display them online, eliminating compatibility problems.
