In addition to the above services, it also provides a high level of security to its database that is secured to a level that cannot be decrypted anyhow.

When it comes to the storage database of Lotus Notes, it makes use of NSF files aka Notes Storage Facility. The items like emails, calendars, tasks, etc. are stored in username.nsf file while the contacts are exclusively stored in names.nsf file.

Consolidating Lotus Notes Archive Files

Lotus Notes NSF files are the main database repository of Lotus Notes. Therefore, there can be multiple NSF files for a single account, which has been in use from a very long time. In addition to this, the user may opt for archiving the Notes database in multiple NSF files, in order to use it for future reference as backup database.

However, at certain times, there may arise a need for merging these multiple NSF files. For example, an employee may need to merge his current NSF file with an ex-employee’s NSF file in order to get acquainted with the different clients and project details. This makes it easy for the user to manage data belonging to both the NSF files together in a single file.

The user can merge all the desired NSF files into a single database and get rid of the task of opening each NSF file when required. The NSF file created after merging can also be used in case the user is upgrading to a new version of Lotus Notes ad want to take the entire data of older version.

3. Backing up different files in single NSF

The user can merge different NSF files into a single NSF file for the purpose of using the output NSF as the backup file. This backup file can be kept for future reference as well as can be used to share the Notes data with other users if required.
