What is the VNT file format?
.vnt files store notes taken on a mobile phone, saved in plain-text vNote format. The vNote type was defined by the IrMC (Infrared Mobile Communications) specification and bears a close structural resemblance to a vCard or vCalendar object.
Contents of .vnt files can be viewed using any text editor, though the note body is often Quoted-Printable encoded - meaning raw sequences like =0D=0A appear in place of line breaks, which can make the file look garbled until decoded. Each file follows this data scheme:
BEGIN:VNOTE- tag marking the beginning of a noteEND:VNOTE- tag marking the end of a note- Encoding information (typically
ENCODING:QUOTED-PRINTABLEand aCHARSETdeclaration) - Creation and last-modification dates
- The
BODYproperty containing the actual note text
The .vnt file format was used by Sony Ericsson and Samsung cell phones - Samsung's S Memo feature in particular produced .vnt exports. Many dedicated apps and online tools exist that can convert .vnt files into full-fledged notes by decoding the Quoted-Printable body and presenting the text cleanly. The registered MIME type for the format is text/x-vnote.
Security & safety
RISK: LOWA .vnt is just a short text note with no executable content, so it is safe to open. The only practical issue is encoding (Quoted-Printable / non-Latin charset) making the text look garbled, which is a readability problem, not a security one. As with any personal export, treat the note contents as private.

Programs that open VNT files
Windows2 apps
Windows Notepad
Built-in Right-click -> Open with -> Notepad to read the raw text; if the body shows '=XX' codes it's Quoted-Printable and needs decoding (see below). 
Notepad
Open-source Open the .vnt, delete the BEGIN/END lines, then use the MIME Tools plugin -> 'Quoted-printable Decode' to turn the body into readable text. 
macOS1 app
TextEdit
Built-in Open the .vnt as plain text; decode any Quoted-Printable body with an online QP decoder if it shows '=XX' sequences. 
Android1 app
Samsung Notes / S Memo
Built-in On a Samsung phone, import the .vnt back into the notes app (S Memo on older devices; Samsung Notes on current ones) to view it natively.
Web1 app
Any Quoted-Printable decoder (e.g. online-convert / dCode)
Free Paste the BODY text (without the BEGIN/END wrapper) to decode the Quoted-Printable into readable text; useful when an editor lacks a QP plugin. Technical details
deep spec| File identification | No binary magic bytes; the file starts with the literal text line `BEGIN:VNOTE` and ends with `END:VNOTE` |
| Format family | vObject - same IrMC-derived lineage as vCard (`.vcf`) and vCalendar (`.vcs`) |
| Body encoding | Note text in the `BODY` property is typically `ENCODING:QUOTED-PRINTABLE`; non-ASCII characters and line breaks appear as `=XX` hex escape sequences |
| Character set declaration | `CHARSET` property declares the encoding per file; common values include `UTF-8`, `ISO-8859-1`, and `EUC-KR` for Korean-language notes |
| MIME type | `text/x-vnote` |
| Line endings | IrMC specifies CRLF (`\r\n`) line endings; real-world device exports sometimes use LF-only |
| Version property | `VERSION:1.1` is the value most commonly found in IrMC-compliant `.vnt` files |
| Metadata properties | `DCREATED` and `LAST-MODIFIED` timestamps stored in a compact ISO 8601-like format (e.g., `19991231T235959Z`) |
| Access-level labeling | Optional `CLASS` property marks privacy level: `CLASS:PUBLIC`, `CLASS:PRIVATE`, or `CLASS:CONFIDENTIAL` |
| Primary device platforms | Sony Ericsson feature phones (late 1990s-2000s) and Samsung mobile devices including S Memo on Galaxy handsets |
| IrMC standard origin | vNote object type defined in the IrMC (Infrared Mobile Communications) specification for short-range device-to-device note synchronization |
| Text editor readability | Technically human-readable ASCII, but Quoted-Printable-encoded bodies appear garbled in Notepad; a QP decoder is needed to display the note text clearly |
| File size | Typically a few kilobytes or less per note; Quoted-Printable expansion can increase size roughly 33% over raw UTF-8 for non-ASCII content |
| Modern import support | Third-party Android apps and online converters decode `.vnt` to plain text; no built-in import in Windows, macOS, or iOS note apps |
| Released | vNote object defined by the IrMC (Infrared Mobile Communications) specification, late 1990s; popularized on Sony Ericsson and Samsung phones |

Frequently asked questions
What is a VNT file?
It's a vNote - a text memo exported from a mobile phone, typically Samsung's S Memo app or an older Sony Ericsson phone. It's plain text wrapped in BEGIN:VNOTE / END:VNOTE markers.
How do I open a VNT file on my computer?
Open it in any text editor (Notepad, TextEdit). If the note text looks garbled with '=20'/'=0D=0A' codes, it's Quoted-Printable encoded and needs decoding.
Why does my VNT file look like gibberish / =20 =0D=0A?
Those are Quoted-Printable escape sequences (=20 is a space, =0D=0A is a line break). Strip the BEGIN/END wrapper and run the body through a Quoted-Printable decoder - Notepad++'s MIME Tools plugin or an online decoder works.
How do I convert a VNT note to a normal text (.txt) file?
Remove the BEGIN:VNOTE/VERSION/END lines, decode the Quoted-Printable body, and save as .txt. The result is the plain readable note.
Can I open S Memo .vnt files back on my Samsung phone?
Yes - import the .vnt into the notes app on a Samsung device (S Memo on older phones, Samsung Notes on newer ones) and it displays natively, handling the encoding for you.
