Hi Mark,
It would appear as if one could use a flash drive to store portfolios and data files if they need to be used between different PC's without internet connection at times.
From what I could gather is that if the MM4 files as well as the DAT files are on the same drive all investments are opened correctly. This looks like the MM4 only gives the path from where it was opened without the path being stored within the MM4 file.
If the same path is thus used on the portable drive than on the PC's would you agree this should work?
Regards.
