Being able to preview the contents of an NSF file before converting it to PST is a huge advantage, especially if you're planning a selective migration. I found this particularly helpful when I used the eSoftTools NSF to PST Converter Software, which includes a built-in preview panel. After uploading my NSF file, I was able to view all emails, attachments, contacts, and calendar entries within the tool itself. This allowed me to double-check the data, select only the specific items I needed, and avoid exporting unnecessary folders. It made the process more efficient and helped maintain better organization in my Outlook mailbox after conversion. If you’re looking for precision and control during migration, a tool with a reliable preview feature is definitely a must.
