Rhino 6: 3DMBAK option off, but still 3DMBAK files

[wim (Wim Dekeyser)]

Thanks for that, Michael!

A bit more information on how Rhino saves a file:

Should I be worried about this?

Here’s a little background about what we do when saving files. This may help you diagnose what’s going on with your sys admin. Consider that you’re saving a file named “MyFile.3dm” Rhino creates a temporary file named something like RHIB4A4.tmp and writes the entire model to that file. Rhino calls Microsoft’s ReplaceFile function which does the following: If MyFile.3dm exists, it is renamed to MyFile.3dmbak RHIB4A4.tmp is renamed to MyFile.3dm If Rhino’s “Create Backup File” option is disabled…

Could you also ask if that also happens for a new file that, for example, only has 1 single line? This problem might have something to do with the size of the file and the speed of server synchronization.
