The main issue with FreeCom would be the location of its resources changing. As long as the comspec env variable still pointed to the same (or an identical) copy of the strings, it would probably be ok, but honestly I don't know if FreeCom closes/opens or keeps open the file with its

Hi, yes, FreeCOM can handle changing drive letters. The PROBLEM is that harddisk letters are handled by a kernel driver which can only do one hole-free range of drive letters. So if you could enable a new partition on the fly, all subsequent drive letters would move. HOWEVER, you are free to

firstly, I never said FreeCom couldn't handle drive letter changes, I said if one did something, then they need to make sure it can; in particular the way it loads strings; although from my experience not being able to load its strings usually just results in FreeCom issuing useless messages
