About SN1 files

A .sn1 file is typically a split volume segment (continuation file) of a complete disk image backup. While broadly categorized as a backup format used by major suites like Acronis Cyber Protect, it is technically specific to Drive Snapshot, a lightweight disk imaging utility. The .sn1 extension represents the second part of a multi-file archive (following the master SNA file).

The Problem: Users often find this file in isolation and cannot open it. Because it contains only a fragment of the binary disk data (offset from the original drive geometry), it is useless without the accompanying header file (SNA) and any subsequent parts (SN2, SN3). It is not a standard document or media file and cannot be viewed in a text editor.

The Solution:

For Recovery: You must locate the full set of files and use Drive Snapshot to mount the image as a virtual drive.
For Conversion: Once mounted, you can extract specific files or convert the virtual disk to VHD or virtual machine formats. There is no direct "converter" for a single .sn1 fragment.

Convert.Guru analyzes your SN1 file, detects the exact format, and lets you read the text inside.

Users also converted SN2, SN4 and SN5 files.
