Cleaning Up Old QVD Files

Vital Signs creates binary qvd files housing all of the extracted data which are stored in the c:\vitalsigns\cu-name\data\qvd directory.

Note: The vitalsigns directory may be located on a different drive than c:\ .

Vital Signs, as of version 1.5, does not attempt to clean up older qvd files. In subsequent versions this may become a feature that can be enabled.

The current recommendations for cleaning up this directory to save on disk space are shown here :

Note : The names listed are the first part of the file names, there will be date stamps appended to them in the qvd directory.

These files contain the daily extracted information for members used by the Analysis_by_Account, Summary and Loan Application documents.

It is recommended that you keep 24 months of daily files and only retain the EOM dated files older than 24 months.
