This box contains the full path name of a file to be read in. There is one for each file to be opened. You can type this in, paste it in, or use the Browse button to the right.

Datasqueeze deals with multiple data types. To change the detector type, it is necessary to use the Browse button. When you do this, in addition to a listing of files in the current folder, you will get a drop-down menu with different detector types. Select the one appropriate for the kind of file you are looking at. If you really have no idea what type of detector your data came from, but are pretty sure it is one of the ones in the list, select "Unknown." The program will try each in turn until it finds one that works (this is somewhat slow).

If there was a problem in opening the file, this text box will be highlighted in red and an error message will appear in the command log.
