What is this file / Where is this file from. It doesn't look like a Trimble DC file - it is some other format and that is why it is not loading (the DC file is a Trimble Format File for managing Raw Data from Survey Controller / Trimble Access or Site Calibration / Coordinate System information from SCS900 / Siteworks or Machine Control Systems.
If I know what the data in the file represents it is possible that the ASCII importer could be set p to read the data - however the data has Alphanumerical fields which may cause a problem decoding unless it is a fixed format field file - in which case the ASCII Importer could be used. You would have to rename the file to e.g. Filename.txt and then on Import it will ask you what Format and then you ca define a field format to import the data.
The first data looks like this
I dont know what B9NM or 0L or 0R represent - and te fact that all three values (166900.000) for example are all the same looks somewhat strange for a NEZ or XYZ or ?? value set and all the lines are the same but with different values - could however be meaningful but looks strange to me - can you shine a light on what this is?
The file then changes to this
and I have no idea what this data represents and I doubt that this could be read by the ASCII importer as that expects one data point per line, so this would likely need a custom importer to read the data, but without knowing the data type / where it is from etc. I doubt that I can help further - I dont recognize the file type? Can you tell us where it is from / what software generated it.
