What is an LSO file?

LSO files mostly belong to SurveyCTO Collect. LSO files are not a single standard file type. Their behavior depends on which program created them.
For example, Survey Data:
  • LSO files can store offline survey responses. Software like SurveyCTO Collect uses these files as a repository for survey answers. They are also referred to as LimeSurvey Offline Data files. See more on the SurveyCTO website.
  • Audio Projects:
  • Some LSO files act as digital audio workstation project files, sometimes called Logic Sound Objects. Tools such as LSOFileReader help manage these audio projects.
  • Lens and Local Storage:
  • Other LSO files serve as Lens Studio Objects for Snapchat or work as Adobe Flash local shared objects. In this case the file holds small data segments for AR lens designs and Flash Player storage. More details can be found on the Snapchat website.
  • Light Show Orchestration:
  • Finally, a variant is used for storing light show choreography data. Light-O-Rama Show Designer employs this format to manage show sequencing, sometimes linking with music notation workflows.
  • FilExt.com tips: The key is to use the correct application that corresponds to the file’s origin. A wrong program may not read the format properly. Always back up your file before editing or converting it.

    How to open an LSO file
