Network Speed

The minimum network speed and reliability must be sufficient to complete the extraction process.

The minimum network speed is difficult to quantify and measure as it is complex and can depend on the volume of information being uploaded.

Browser Processing

The Chrome and Firefox browsers download a vclient.application which when clicked on "Download", the vClient core files into the %APPDATA% Validis Storage location.

The Microsoft Edge browser, typically, automatically opens the file vclient.application in the browser.

 

vClient Core Files

The downloaded files are automatically deleted from the Validis\Storage location when vClient Upload processing is complete.

Download file processing

The files are downloaded with the “deploy” file extension and are converted to a DLL executable binary by ClickOnce.

Other conversions occur, for example, icon files of type “ico”.

 

A call is made to a Web endpoint to download the required files.

For example, when System.Text.Json.dll.deploy is downloaded it will become System.Text.Json.dll.
