Q - How do I split a large NSF file before conversion to avoid data corruption or migration errors?
A - When dealing with large NSF files, splitting them before migration is a smart step to prevent corruption, timeouts, or data inconsistency. Unfortunately, Lotus Notes doesn’t provide any built-in option to split NSF files, and manually dividing them can be complicated and error-prone. Handling large files manually also increases the risk of losing important emails or attachments during the conversion process.
A better and safer solution is to use eSoftTools Lotus Notes NSF Splitter Software (or its NSF to PST version). This tool allows users to handle even very large NSF databases efficiently. While converting, it offers an optional PST splitting feature, letting you divide oversized mailboxes into smaller, more manageable PST files (by size).
Moreover, the software preserves all data attributes — including folder hierarchy, formatting, and embedded attachments — even for large files. With built-in integrity checks and a preview feature, users can ensure every item is safe before and after migration. If you want to avoid errors and ensure smooth performance, using eSoftTools software is the most efficient and risk-free way to manage and migrate large NSF files.
