I have a question about a specific problem and a general question about the best way to store my data for use in my Virtual Machine. I use an email indexing application called X1 within my Windows VM. My Windows Outlook PST files and the X1 application became corrupted when I stored my PST email files in my OSX file system. When I moved them to C:\... in my Win 10 virtual machine, they stopped getting corrupted. As I understand it, PST files are written to by Outlook and X1 frequently during use, even when the user is not modifying them. Should applications running within Parallels be able to handle PST files stored in the OSX HFS filesystem? In general does storing my files in the OSX HFS file system or the VM NTFS make a difference to performance or corruption protection? What about storing files on a Bootcamp partition, which I think Parallels can access? I also had Tuxera NTFS installed in OSX when I ran into my corruption problem. Is there any conflict between having Tuxera NTFS and Parallels installed, given that both seem to have some capability to interact with NTFS?
