A QVD (QlikView Data) file is a file containing a table of data exported from Qlik Sense. QVD is a native Qlik format and can only be written
to and read by Qlik Sense or QlikView. The file format is optimized for speed when reading
data from a script but it is still very compact. Reading data from a QVD file is typically 10-100 times faster than reading from other
Note: This function is not supported in Qlik Sense Cloud.
