I got the NSF Converter, which was the best utility available for purchase. This is the only software that did not crash during the conversion of large 25 GB files. More to the point, I had a slow VM, so I upped the CPU and RAM. Unfortunately, this caused my gadget to lose its activation. It took 7 minutes with TrustVare assistance to rectify the issue, and I am once again a pleased user of their converter. I'll stress it again. Every other tool I've used has failed in some way. This one appears to be the best so far.
I used this tool to convert my file and its easily converted all emails quickly. Saved my time and money. Thanks trustvare
