I'm a Total Commander (TC) file manager user. Having some problems accessing VBox shared folders from Total Commander from inside a VBox Windows VM, i posted the issue in TC's forum. It seems that it's a long standing issue (TC when trying to access a VirtualBox shared folder from within a VM, fails), and the reasons for the failure are unknown. Could anyone perhaps shed some light on the matter and perhaps make a proposal to resolve this issue?
The relevant thread with the details from TC's author is here.
