 Frequently asked questions
 ==========================
 
+
+Using an ancillary file
+~~~~~~~~~~~~~~~~~~~~~~~
+
+Q: I use the “Quick upload” to submit a measurement file together with an ancillary 
+file. Will this ancillary file be used in processing of my measurement. 
+
+A: No. Which ancillary file is used when processing a measurement is defined in the 
+measurement netcdf file. If your new ancillary file is not  mentioned in the measurement 
+file, it will not be used.
+
+
+Reusing an ancillary file
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Q: I want to use one ancillary file (ex. an overlap file) in the processing of multiple
+measurements. Do I need to submit it multiple times? 
+
+A: No. You just need to define the file name of the file to use in the measurements
+netcdf file.
+
+
+Deleting an ancillary file
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Q: I want to delete an uploaded ancillary file but in the "Admin" interface I can't
+find a "Delete" button.
+
+A: Probably the ancillary file you are trying to delete is needed by some uploaded 
+measurement, and for this reason you are not allowed to delete it. You will need
+to delete the corresponding measurements first, before deleting the ancillary file.

 A: At moment you should provide cloud free data because the automatic cloud screening 
 is not yet implemented in the SCC. We are working on this issue and hopefully the new 
-module will be implemented at the end of ACTRIS project .
