Do you have no idea how to split NSF file and are you looking for the NSF file splitter? If yes, then you are on the right page. Here you will get amazing and highly advanced methods to split NSF file HCL Notes.

Lotus Notes evolved into IBM Notes with the release of version 9 and later. The application suite is a preferred choice among large-scale enterprises. This probably happened because of the fact that Notes features strong security measures.

Moreover, Notes is more of a collaborative platform that features communication apps, database creation, objects, documentation, and more. With so much to store, it was necessary for IBM to offer a good storage capacity to the database (.NSF).

Nevertheless, there has to be a limit too which when crossed showed up errors. Thus, demands to split NSF file grew among users when all else seemed to fail. Despite it all, there have been instances where the storage provided by IBM did not seem enough for users leading to errors. Even though this could be, an administrative fault that the database is unable to store more than what it is.

Reasons that Compel Users to Split NSF

Just like any other application or client, IBM Notes evolved and so did its features and potential. As a result, the latest series of IBM Notes versions – you can store up to 64 GB of data in your NSF file. Exceeding this limit could show up error message and could cause much worse to happen.

The Problem: However, 64 GB isn’t completely usable. Because on approaching the limit itself there is a high possibility of surfacing performance issues such as:

  • Application failure
  • Crashing of server
  • Performance slows down

Top 3 Tips to Prevent Running Out of Storage

Prevention is always better than cure. The idiom goes well for IBM Notes database management too. In order to prevent surfacing errors or running out of storage space in your Notes database, it is better to follow database management tips. Some of the common and easily applicable ones are discussed as follows to help you avoid a situation to split NSF file HCL Notes:

Compact NSF File

The concept of deleted items leaving behind white spaces is common for most file types. Similar is the case with IBM Notes, which develops white spaces on the deletion of attachment or documents large.

NOTE: The white space is maintained in order to leave behind a scope of recovery in the future, just in case required.

Nevertheless, this white space denotes that the item deleted is not removed from the file. But is marked as deleted until it is ‘replaced’ by a new entry into the database. Therefore, this white space can be eliminated and used for recreating more storage in the database instead.

Therefore, to do so, Notes features the option to compact a database by removing these ‘white spaces’ and regenerating new storage space from it.

TIP: Compact -I continue to process and compact the database even when corruption is detected.

Delete Items Unnecessary

Items whether in the form of objects, emails, documents, or attachments, when unnecessary to you, must be deleted to save up on the storage. These little entries are what end up taking the most space in your database. There is clearly no necessity to keep a document or email that is going to be of no use to you in the future. And does not hold any crucial information. Thus, deletion is one of the best steps to create space in a database having no scope of storing more data.

NOTE: Attachments take up the most space, as they are not limited to a standard type and could be a document or a media file which vary in size.

All Documents Archiving

All Document is a directory where Notes maintains a copy of all the created and exchanged information. Whether existing in the database or not. Thus, this usually takes up a lot of space eventually. Even though there is archiving option available, most of us skip using it wisely. All Documents is a folder that maintains a copy, i.e., double the storage of the same items and objects. Therefore, what is necessary but not on a regular basis can be archived to prevent the primary database from filling up soon.

Even users can implement these simple workarounds on their own without administrative help. Thus, it is suggested that whenever possible one should ensure the maintenance of their account and its database for convenient performance and user experience.


Limited storage capacities have ruined the scope for many applications to stay in the market for too long. We have always had the option to switch, if the current application is not working up to the mark; let us switch to another one of a similar kind.

That is what we do, we never deal with the consequences and stick to one application. Third-party applications help you do just that by letting you work with the same application without the issues that you had been facing previously.

Split NSF is just another such application that is capable of splitting oversized NSF files with the help of different split modes. The best thing is you get to try the software beforehand and see for yourself that the tool works fine.
