Opening an NMMM File
The NMMM file type is primarily associated with Samsung SmartSwitch.
What is an NMMM file?
NMMM files mostly belong to Samsung SmartSwitch. An NMMM file format serves as a secure container for memo backups. It often holds your memo data in an encrypted archive format that protects the information from unauthorized access.
Primary use: It is commonly used for Samsung Notes Memo Backup through SmartSwitch, where the file uses a ZIP structure for encryption. Alternative use: Some versions are created as NimbleText encrypted memo files, which are stored in an encrypted RAR archive. The encryption ensures that your memos are kept safe during transfers or backups. To open or restore these files, use the original software such as Samsung SmartSwitch or the NimbleText memo tool. More details can be found at the Samsung SmartSwitch webpage.
FilExt.com tip: This setup means that even though the extension remains the same, its internal structure could differ, requiring proper decryption for access.

Programs that open and convert NMMM files:
- Samsung SmartSwitch
See the previous paragraphs to learn more about the main application. NMMM files are often referred to as Samsung SmartSwitch backups because this type of file is primarily created or used by this software.
- Samsung Notes*.NMMM files are primarily associated with Samsung Notes, serving as backups for notes created within the app. These files typically employ either the encrypted RAR archive format or the standard ZIP format, often facilitated by SmartSwitch for backup and transfer purposes. The encryption applied to these archives ensures the confidentiality of the stored notes. Recognizing these files as Samsung Notes Memo Backup files clarifies their function. While NimbleText encrypted memo file might appear relevant, it's less accurate than associating them with Samsung Notes. Similarly, Memo Notepad is a broader term and doesn't precisely reflect the origin of these files. This file format is classified as data.
NMMM file extension format:
A file format defines how the data in the file is structured. The first characters in a file identify the file format, for example, HTML files start with the bytes <html>. File extension, signature and file format must match; otherwise errors will occur when the file is opened. If there are problems opening a file, you must first determine the file format used. Our analysis of the NMMM files produces the following result:
NMMM is seldom used as a file extension and includes different formats for different programs. The following file formats are most commonly found in NMMM files:
- 50% of all NMMM files use the ZIP algorithm, so several files are compressed and saved in one NMMM file. Such a ZIP file contains 3 to 3 files. File names are e.g. SSMDummyValue.exml, SmartSwitchBackup.json and memo.bk. You can see the included files and images by renaming the file extension to .zip and then double-clicking it. The files are on average 500 KB in size and range from 41 KB to 9 MB. The following keywords are characteristic: memo.bk. A usual file name is Memo.NMMM.
- 45% of all NMMM files save the data in SAMSUNG file format. The file is a SAMSUNG Kies backup file, used to backup and recover from Samsung devices using Kies. Samsung has released new software to replace Kies, named Samsung Smart Switch, which is mainly directed at migrating customers onto new Samsung devices. These files contain neither text nor words, but only data. A typical file size is 150 KB. Some examples of file names are memo.nmmm.
The remaining 5% of all NMMM files are different files with different signatures. Just click the "Choose your .nmmm file to analyze" button on this page to find out what your NMMM file is.
