Security of QVW File Type

Mon, 26 Jan 2026 18:19:17 GMT

Hi,

I have a doubt about the security of the qvw file type.

For security terms in a client, I can't store sensitive information of persons in QVD files, so for load this information in the QVW that is accesible through AccessPoint, I accede to the database directly.

My question is, what kind of security does the qvw file type? My QVW has a section access for controlling the opening, but I am thinking more about the structure of the file, is encrypted in some algorithm?

Thank you very much!

Regards,

Guzmán.

qvw is a binary compressed format.

Hi, thank your for your response.

If the file is compressed in binary format, this gives me access security from unauthorized third parties? I must comply with the PCI-DSS security regulations and my doubt is about the persistence in hard disk of sensitive persons information.

Thank you.

Guzmán.

Qvw documents are not encrypted. Section access does not secure qvw files against persons trying to extract data from them. That means you need to restrict access to the qvw files by using for example file sytem permissions.
