The files named existed and could be opened at a later time with no problems. On a hunch, I increased the ulimit of file descriptors from 256 to 1024 and restarted the virtual machine. After then I was able to use VStudio without errors. (I was also able to reproduce the error by attempting a Windows command line copy of the project with ""xcopy /s "") It would be helpful if when VirtualBox encounters EMFILE errors to log a notice (rate limited if need be) to the log file for the machine to give a hint as to the problem.",defect,closed,shared folders,VirtualBox 2.1.0,fixed,,,Windows,Solaris
