How to choose the right PST to vCard Converter for Windows users?

I have multiple large PST files (over 10GB) in Outlook and want to convert contacts into vCard format. Most tools either crash or slow down during the process. Can anyone suggest how to choose a reliable PST to vCard converter that handles large data efficiently on Windows?

ensure you have enough RAM/memory in your computer for this process. It could be the cause of all of this. Swap/pagefile use then out of memory.

ctrl + shift + escape brings up task manager to view memory usage.

It is common, however, for an app to crash on enormous files no matter what.

Outlook has built-in way to export to CSV (Comma Separated Values) file. Then you may find something to convert it to vCard format or use a transitional app which supports importing CSV.

If you have multiple PST archives, most probably you already have Outlook where to mount them. :)
So, open Outlook, attach the desired PST file and then from the Menu File > Open & Export > Import/Export > Export to a file > Next >Comma Separated Values. Then select the Contacts folder > Next, name and generate the file.
