qvd is a qlikview native file..

it is much faster than other file ..suppose if u have excel or any other file ,u wnt to convert tht file to qvd mean this is the syntax  store tablename into  and the location where u r getting the excel file \newfilename.qvd

QVD means qlikview data  file.

for qlikview applicaiton the source files are qvds, qvds are binary files and loading the data from qvds is much faster then loading the data from regular file.when u bbuilt the applciations with qvds ur application size also minimizes.

qvds are only understable by qliview.

u can also load the data from excel files and built the applciation  as long as u have limited data.

U will find the differnece when working on large sets of data.

A QVD file contains the data from a table in QlikView dumped directly from memory to disc. So, a QVD file is a data file and contains one table.

If you reload it as is, it doesn't need processing, so the reloading of that data is very fast.

Hi Vinod,

QVD (QlikView Data) - is a native QlikView format and can only be written to and read by QlikView. The file format is optimized for speed when reading data from a QlikView script but it is still very compact. Reading data from a QVD file is typically 10-100 times faster than reading from other data sources.


1. Single Source of Truth – QVDs promote re-use of common data sets which helps create a single source of truth for your QlikView deployment

2. Resource Flexibility – developing a QVD layer can be primarily an I.T. responsibility, allowing the interface design to be handled by Business teams and less technical resources.

3. Development Flexibility – QVDs are offline components and allow developers to develop, test and validate data offline from databases

4. Development Speed – having a library of QVDs built allows a developer or designer to very quickly identify, load and test data sets that might otherwise take database and SQL skills to get

5. Delivery Flexibility – QVDs can easily be aggregated, segmented orotherwise modified to meet the specific needs of dashboards. This is much easier than re-writing queries.

6. Incremental Loads – very large datasets benefit greatly from incremental (delta) loads. QVDs accommodate any type of incremental load, saving time and resources each day

7. Very Fast Data Loads – once created, a QVD file can be loaded into a QlikView document as rates of 10-100 times faster than the original query speed.
