you can encrypt files easily enough (for instance, using ebcrypt from vb, vba or vbs, but - what is the end goal here?

thank you.
I am creating a VB application that will manage confidential information related to payroll. Some files related to each employee are JPG files. People from IT infraestructure area which es responsible for servers must not have access to view the content of the JPG, they can only backup the information.

best regards

Problem you are going to have then is decrypting the data "on the fly" and using it, rather than encryption/decryption - if you decrypt the files to load them, then they will be accessable on disk when in use (mind you, there is little to be done about that anyhow against internal IT)

You have two real choices.
First, you can encrypt the data files and decrypt them at need - ebCrypt above will be fine for doing that.
Second, you can do "on the fly" file encryption, using either a third party app such as truecrypt, or MS EFS. EFS isn't absolutely proof against access, but is certainly good enough to prevent anything but a determined effort to break, and is effectively transparent for you and your users.
