How to Open .WS Files on Windows
A .WS file is a WordStar document, and no application shipped with modern Windows can open it. The reliable fix is to convert it.
TL;DR
Windows 10 and 11 ship with nothing that opens .ws files, and Word has no WordStar filter. Install the free WordStar Converter trial, add your .ws files, and convert them to Word (DOCX) or PDF — locally, in bulk, with nothing uploaded.
How to convert WordStar to Word or PDF — step by step
Install WordStar Converter (free trial)
Download the installer for Windows 10/11. The trial opens and converts up to 10 files free.
Add the .WS files you can’t open
Drag in individual files or a whole folder. Uppercase .WS names and .wsd / .ws3–.ws8 variants are all handled.
Choose Word or PDF
Pick DOCX to keep editing the document, or PDF to read, print, and share it. You can output both at once.
Convert and open the result
Click Convert and open the new file in Word or your PDF reader. The original .ws stays untouched.
Why won’t my .WS file open?
A .WS file was created by WordStar (MicroPro, later WordStar International). Windows has no viewer for it. Microsoft Word has never had an import filter. LibreOffice’s filter is incomplete. That is why a double-click gets you an error or a screen of high-bit garbage.
You do not need a DOS VM and a 1980s install to read these documents. WordStar Converter parses the file natively: unwraps high-bit wrap, maps print controls, and honors dot commands. Convert each .WS to Word or PDF and you get a document that opens everywhere.
Safer than online WordStar converters
Searching for a "free online WordStar converter" means uploading your files to someone else's server — a real problem for contracts, case files, personnel records, and anything else confidential. WordStar Converter runs entirely on your Windows PC: files are converted locally and never leave your machine. It also handles thousands of files in one batch, which no upload-one-file-at-a-time website can do.
The free trial converts up to 10 files with every feature enabled — for most people that's the whole job. Larger archives are covered by a one-time $39.95 lifetime license. No subscription, no watermarks, no uploads.
Frequently asked questions
Is there a free way to convert .WS to Word?
Yes. The free trial of WordStar Converter converts up to 10 files with full features — no signup and no watermarks. Unlimited conversions are a one-time $39.95 license (no subscription).
Is this an online converter? Do my files get uploaded?
No. WordStar Converter is a Windows desktop app. Every conversion runs locally on your PC. Nothing is uploaded.
Can I convert an entire folder of WordStar files at once?
Yes. Point the app at a folder (it scans subfolders), select Word as the output, and it batch-converts .ws, .wsd, and .ws3–.ws8 files in parallel.
Which WordStar versions are supported?
WordStar Converter reads classic WordStar documents through Release 7, including high-bit wrap flags, print controls 00h–1Fh, 1Bh xx 1Ch extended characters, 1Dh symmetrical sequences, and dot commands. EOF is 1Ah. Microsoft Word has no WordStar import filter. LibreOffice has a limited WordStar filter that often mangles wrap flags and sequences — a native parser is the reliable path.
Is there a free .WS viewer for Windows 10 or 11?
There is no maintained WordStar viewer for modern Windows. Converting the file is the dependable way to read it — the WordStar Converter trial does this for up to 10 files free.
What is a .WSD or .WS7 file?
WordStar used several extensions across releases: .ws, .wsd, and versioned .ws3 through .ws8. The converter treats them as the same family of WordStar documents.
