WARNING: “Shared Folders” and Microsoft Virtual PC

Microsoft Virtual PC includes a “Shared Folder” facility to enable the Guest Operating System to access files on the Host’s Hard Disk Drive. This seems to work fine for small files, but I recently discovered this to be extremely unreliable when transferring very large files. In my case, this was “forklifting” 5GB worth of Exchange Server Database files. The files appeared to copy across correctly, but in fact they were badly corrupted in transit – and failed to mount properly on the Guest OS. I re-tried this several times (even to the point of creating some “.par” parity files to accompany them). As a result of this experience, I would recommend utilising “Network Shares” to transfer ALL files between the Guest & Host Operating systems. I have so far found this mechanism to be flawless…
