What is the difference between “Save as .csv” and “Save as .scsv”?

A .csv file is an Excel-compatible file – it can be opened with Excel with all data sorted into columns. The .csv file, however, can be opened (viewed) in the QuickScan program, but not edited. A .scsv file can be opened and edited using the QuickScan program. The DataLog is actually a .scsv file. It can be opened with Excel, however, the data is not sorted into columns and will need to be sorted manually.
