Your Control Center data includes your documents and printing history logs. All the data is stored in your Control Center SQL database.

You store your label files, solutions, graphics, and other files in the Documents storage. Control Center generates History logs automatically and logs data size depends on the frequency of your printing activities.


In time, the size of stored data can reach several Gigabytes, which may affect the performance of Control Center. To avoid performance issues, you can archive your History logs if you go to Administration > Archiving.

  • To enable periodical archiving, select the option Perform scheduled cleanups, then define Cleanup Configuration settings.

  • You can periodically perform cleanup of your Control Center SQL database by deleting the old content or arriving the old content to your local Access database.

  • With Organize archive data options you can create a new archive file for each cleanup or ad data to the same file.

Recovering archived data

After the history log cleanup, Control Center stores the archived data in Access database files. The archived data is no longer directly visible in the History tab. If you want to make the archived data visible again, your Control Center allows you to recover the history data from the archive Access database files.

The recovery procedure imports the archived data back to the Control Center database and makes the data available for viewing and further analysis.


Use the archived data recovery option if you plan to conduct an audit that requires checking the already archived data stored in Access database files.

  1. To recover the archived data, run the dedicated Archive Importer application that you can find in your Control Center installation folder. The default path is: c:\Program Files\NiceLabel\NiceLabel Control Center\Utils\ArchiveImporter.exe.

  2. Click Import. The file browser window opens.

  3. Locate your Microsoft Access archive database file. If your archive uses separate database files with time stamps, make sure you select the file for the relevant time period.

  4. Click Open. Your archive data becomes visible again in the Control Center History.

Because reimporting the archived data adds load to the Control Center database and slows down the performance, you can delete the recovered data after you are done with the audit. To delete the recovered archive data, click Delete.


During the archive data recovery, your Access database files remain stored on your computer. If you decide to delete the recovered archive data from your Control Center, you still keep the original Access database files and all history data that is visible on the History tab.

The recovered archive data is excluded from the data archiving in Control Center. The recovered data remains visible on the History tab until you delete the data using the Archive Importer application.
