How to Open and Read .SAM Files in Windows 10 and 11
Question details
The user needs to know how to open or read files with the .SAM extension on modern Windows operating systems.

- Product
- Windows
- Device & OS
- Windows 10, Windows 11
- Scenario
- Attempting to open a legacy .SAM document created on an older operating system like Windows 7 using a modern PC.
- Observed behavior
- Windows 10 and Windows 11 do not include a built-in reader for the .SAM file format, preventing the files from opening directly.
Verify whether your .SAM file is a standard text document (such as a legacy Lotus Ami Pro file) or a Windows Security Account Manager (SAM) system database file. Never attempt to modify or open system SAM files located in core Windows directories, as this can severely damage your operating system.
Use a Third-Party Document Converter
Convert the legacy Lotus Ami Pro document into a modern, supported file format like .DOCX or .TXT.
The .SAM file extension is most commonly associated with Lotus Ami Pro, a legacy word processing software. Since Windows 10 and 11 lack native support for this format, you must rely on a dedicated conversion service to modernize the file.
Open Windows File Explorer, navigate to your .SAM file, right-click it, and select 'Properties' to ensure it is a document file and not located inside the C:\Windows folder.
Open your web browser and navigate to a reputable online document conversion tool that explicitly supports the Ami Pro .SAM format (such as Zamzar or FileZigZag).
Click the 'Choose Files' button to upload your .SAM document. Open the output format dropdown menu and select a modern format like '.DOCX' or '.TXT'.
Click the 'Convert Now' button. Once the process is complete, click 'Download' to save the converted file, which can now be opened in any modern word processor.

Consult Microsoft Support Communities for Legacy Workarounds
Seek specialized assistance if you cannot identify the exact file format or lack compatible legacy software.
Manage Converted Documents Easily with WPS Office
While modern operating systems no longer support the legacy .SAM format, WPS Office provides a lightweight, highly compatible platform for viewing and editing your files once they are converted to standard formats.
- 1. Install WPS Office: Download and install WPS Office on your Windows 10 or Windows 11 PC.
- 2. Open the converted file: Launch WPS Writer, click 'Open' on the left sidebar, and select your newly converted .DOCX or .TXT file to start editing.

Frequently Asked Questions
What is a .SAM file?
A .SAM file is typically a document created by Lotus Ami Pro, an early word processing application. However, the .SAM extension is also used by the Windows Security Account Manager (SAM) system database, which stores user passwords and should never be manually opened or modified.
Can Microsoft Word open .SAM files directly?
No. Modern versions of Microsoft Word do not include built-in support or text converters for Lotus Ami Pro .SAM files. You must use a third-party legacy file converter to change the file to a standard format like .DOCX before opening it in a modern word processor.
Is it safe to use online file converters for my .SAM files?
Using reputable online file converters is generally safe for everyday documents. However, you should avoid uploading .SAM files that contain sensitive, confidential, or personal information, as complete data privacy cannot always be guaranteed by free online services.
