Use the sysFile command to perform common filesystem operations on files.
// Move a scene to the new directory (we can rename it at the same time).
sysFile -rename "C:/temp/mayaStuff/myScene.mb.trash"
"C:/maya/projects/default/scenes/myScene.mb"; // Windows
sysFile -rename "/tmp/mayaStuff/myScene.mb.trash"
"/maya/projects/default/scenes/myScene.mb"; // Unix
// Rename the scene to "myScene.will.be.deleted"
sysFile -rename "C:/temp/mayaStuff/myScene.will.be.deleted"
"C:/temp/mayaStuff/myScene.mb.trash"; // Windows
sysFile -rename "/tmp/mayaStuff/myScene.will.be.deleted"
"/tmp/mayaStuff/myScene.mb.trash"; // Unix
// Copy a scene to the new directory
string $destWindows = "C:/temp/mayaStuff/myScene.mb.trash";
string $srcWindows = "C:/maya/projects/default/scenes/myScene.mb";
sysFile -copy $destWindows $srcWindows; // Windows
string $destUnix = "/tmp/mayaStuff/myScene.mb.trash";
string $srcUnix = "maya/projects/default/scenes/myScene.mb";
sysFile -copy $destUnix $srcUnix; // Unix
// Delete the scene
sysFile -delete "C:/temp/mayaStuff/myScene.will.be.deleted"; // Windows
sysFile -delete "/tmp/mayaStuff/myScene.will.be.deleted"; // Unix
Manipulating the open scene file
The file command lets you perform various functions from the File menu, functions for manipulating files and references and their contents, and functions for testing files.
Refer to the MEL reference page for file for a full listing of its options.
