There are a few types of files.
The first being the native Direct scan data file which is typically ds_data.xxx. xxx being 000, 001, 002.etc or file.dat. This file can only be read by others with DS so if you want to post that file so others can read it and make sure that it is really the correct file, run DS and load that in- I forget off the top of my head where it is in the menus of DS but just poke around or someone else can answer this.
Another type of file is an exported csv file that is just a comma separated database. It is the raw data and I don't think DS can import this, but a database program such as Access, mysql, or a spreadsheet program such as Excel can import this.
So if you want others to view your DS runs, it's better to post the data file not the csv file.
If you want to make graphs or do math with the data you want to export the csv file and use a spreadsheet.
BM computer posts the .dat files.
