A system and method is provided for switching file systems underneath working processes. An exemplary method includes identifying a process running on an operating system of a computing device that is using a file on a first file system and temporarily suspending execution of the process. Moreover, the method includes identifying existing references of the process to access the file on the first file system during execution of the process and replacing the existing reference of the process with a new reference for the process to access a second file on a second file system during execution of the process. Moreover, the second file on the second file system corresponds to the first file on the first file system. Finally, the method includes resuming execution of the process on the computing device.
