The Data Management - Local History page of the Preferences dialog


The Data Management – Local History page of the Preferences dialog allows you to set up the local history related features.


The Data Management – Local History page is part of the main Preferences dialog that is accessed by clicking the  control in the upper-right corner of the workspace then selecting the Local History entry under the Data Management folder.


Local History

  • Number of days to keep documents in history - use the up/down arrows to change the number of days to keep the documents in the history repository. Once the number of days have been exceeded, those documents that are older than the defined number of days are erased from the repository.
  • Add autosaved documents to history - enable this option to add the auto-saved documents to the local history repository. However, their life span is limited by the number of days the documents are allowed to remain in the local history repository.


  • Use global repository - enable this option if you want to have all local histories of documents in different projects in Altium Designer stored in one global repository. You can define the path to the global history repository.
  • Global repository - edit the path to the global repository or click the Browse Folder button on the far right of the path field to open a dialog and choose the folder in which you want the global repository to be stored.
For a default installation, the path for the global repository will be: \Users\<ProfileName>\AppData\Roaming\Repository.
