Hi,
QVD are qlikview data files.
Its a QV format for storing data. Highly compressed, fast to load etc are advantages.
For details please find the attached file.
Qlikview Stores data into Qlikview format file (QVD)
At a basic level a QVD is a flat data file with the extension .qvd. It can store a single table of data (is. each row shares the same column list) and is typically created in the load script of a QVW file. The structure of the file is essentially an XML format, with various bits of header information stored at the top of the file and the rest of the data beneath. One of the beauties of a QVD file is that it is compressed on creation using the same algorithms as QlikView uses to store data in memory – so the files can be incredibly small for the amount of data they contain. Loading from QVD back into memory is blindingly fast as the format of the file mirrors how QlikView addresses data in RAM
Major Use of this file used for implementation of Incremental Load.
Hope this help you
