When creating a new file in the latest DataGraph Beta version, you now have the option to save in a new single file format called .dgraphs.
This format is recommended for use when saving files on cloud services like One Drive with the on demand option turned on. In the past, it was recommended to turn off on demand when using the original package file format (.dgraph), which looks like a single file on your Mac but is actually a series of folders. However, if you have large amounts of data and are not using a cloud service, the package file format may be faster.
Try out the new format by downloading the current beta version. If you have any issues please let us know. Thanks!
