Historian Dataset Management

Learn the role of each file type within a dataset.

For Window's applications, datasets are stored by default in C:\ProgramData\Flow Software\Timebase\Historian\Data\

Within that directory, you will find a list of all of your datasets as well as the historian.state file.

Each dataset contains the same types of files.

• Extension .data files are Timebase history blocks for numeric and Boolean values, created hourly
• Extension .object files are Timebase history blocks for object values (e.g. strings, json blobs, arrays, etc.), created hourly
• The dataset.state file maintains the current state of the dataset, which is used on dataset initialization to determine whether any hourly history block recovery is required
• The tag.state file maintains the current state of each tag in the dataset, which is used on dataset initialization
