Sometimes when you try to create a QTVR file, you receive the following
message although the file does not exist and the disk is not full:
On Windows:
Could not write abcd.mov (No such file or directory). Is the disk full or
write protected? Or is the file open in another application?
On Mac:
Could not write abcd.mov (Cross device link). Is the disk full or write
protected? Or is the file open in another application?
