LabAnalyst can open a wide variety of file types, including legacy through modern versions of Warthog files, Sable SSCF and ExpeData files, and tab or comma-delimited text files (.csv, and similar spreasdsheets). You can also elect to access a subset of file types, using the button on this window, as follows:
Warthog Only Accesses only Warthog-format data files with these extensions: .whsc   .whog   .WHdata
Sable or Warthog Binary Accesses Warthog and Sable-format binary files with these extensions:.whsc   .whog   .WHdata   .exp .expS   .sabl   .WHSable
Any Sable or Warthog File Accesses all files; allows loading of any Warthog and Sable-format files regardless of extension, but only correctly-formatted files will open successfully
Text (.txt; .csv) Allows access to all files; allows loading of tab- or comma-delimited text files (not usable for Warthog or Sable files)
