How to Fix “There Is Not Enough Memory or Disk Space” in Microsoft Word

Opening, editing, or saving a document in Microsoft Word only to be halted by a blunt dialogue reading “There is not enough memory or disk space to complete the operation” (or “Word cannot display the requested font”) is an alarming error. Checking your system storage reveals hundreds of gigabytes of available hard drive space, and Task Manager confirms plenty of free physical RAM, leaving users baffled as to why Word claims resources are exhausted.

This misleading error message is rarely caused by actual hardware storage exhaustion. In Microsoft Office architecture, Word uses internal 32-bit memory buffer pools and legacy temporary scratchpad pointers. The error triggers when the global default template (Normal.dotm) becomes corrupted, when Microsoft Word Data registry keys store invalid binary state definitions, when third-party COM add-ins leak memory handles, or when the Windows temporary folder fills with thousands of abandoned scratch files. This tutorial details how to eliminate the error and restore Word stability.

Method 1: Reset the Corrupted Normal.dotm Global Template

Every new document in Microsoft Word is spawned from the global template file named Normal.dotm. If this file suffers corruption over months of edits and style changes, Word fails to allocate document buffers.

1. Close Microsoft Word and all other Office applications completely.
2. Press Windows + R to open the Run dialogue box.
3. Type the following directory path and press Enter:

   %appdata%\Microsoft\Templates

4. In File Explorer, locate the file named Normal.dotm. (If you cannot see file extensions, click View > Show > File name extensions).
5. Right-click Normal.dotm and select Rename. Change the name to Normal.dotm.old.
6. Relaunch Microsoft Word. Word will automatically generate a brand-new, uncorrupted Normal.dotm template file with pristine factory defaults.
7. Test opening your documents to verify if the memory error has vanished.

Method 2: Clear Corrupted Word Data and Options Registry Keys

Microsoft Word stores user preferences, toolbar customizations, and recently opened file caches inside binary registry keys. Deleting the Word Data key forces Word to reset its internal memory allocation pointers.

1. Press Windows + R, type regedit, and press Enter to launch the Registry Editor.
2. Navigate to the appropriate registry key corresponding to your Office version:

   HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Word

   (Note: 16.0 applies to Microsoft 365, Word 2021, Word 2019, and Word 2016).
3. Under the Word folder, locate the subkey named Data.
4. Right-click the Data key and select Delete. Confirm the deletion prompt.
5. Next, locate the Options subkey under Word. Right-click and select Delete.
6. Close the Registry Editor and restart your computer. When Word launches next, it will reconstruct fresh, uncorrupted registry hives.

Method 3: Purge the Windows Temp Directory of Abandoned Scratch Files

When Microsoft Word opens documents, it generates hidden temporary files beginning with a tilde and dollar sign (e.g., ~$document.docx). If Word crashes, these temporary files remain locked in your temporary storage, eventually hitting internal directory file ceilings.

1. Press Windows + R, type %temp%, and press Enter to open your user Temp folder.
2. Press Ctrl + A to select all temporary files and folders.
3. Press Shift + Delete to permanently delete them. If a dialogue warns that certain files are currently in use by active applications, check “Do this for all current items” and click Skip.
4. Next, press Windows + R, type temp, and delete files inside the Windows system temp folder as well.
5. Empty your Recycle Bin.

Method 4: Launch Word in Safe Mode and Audit COM Add-ins

Third-party add-ins (such as PDF editors, grammar assistants, or citation managers) hook directly into Word’s memory allocation space. If an add-in leaks memory handles, Word runs out of internal buffer space.

1. Press Windows + R, type winword.exe /safe, and press Enter.
2. If Word opens cleanly without displaying the memory error, a COM add-in is the verified cause.
3. Click File > Options > Add-ins.
4. At the bottom of the window, ensure Manage: COM Add-ins is selected and click Go….
5. Uncheck all active third-party add-ins and click OK.
6. Close Word and relaunch it normally. Re-enable add-ins one by one to identify the defective software.

Microsoft Word Memory Error Diagnostics Reference Table

Use the matrix below to assess the source of memory and disk space errors in Word:

Observed Warning Trigger	Probable Root Cause	Recommended Solution
Error on launching Word or opening blank document	Corrupted Normal.dotm global template	Rename Normal.dotm to Normal.dotm.old in Templates
Error occurs when saving a complex document	Corrupted Word Data registry hive	Delete Data key in HKEY_CURRENT_USER\…\Word
“Word cannot display the requested font”	Windows font cache exhaustion or corrupted font file	Rebuild Windows font cache in Service console
Error strikes on documents with many high-res images	32-bit Office architecture 2GB virtual memory limit	Upgrade to 64-bit Microsoft 365 / Office installation
Error accompanied by slow document scrolling	Defective third-party grammar or PDF COM add-in	Disable COM Add-ins via File > Options > Add-ins

Upgrading from 32-Bit to 64-Bit Microsoft Office

Many legacy enterprise systems still deploy the 32-bit edition of Microsoft Office. The 32-bit architecture enforces a strict 2GB virtual memory ceiling across the entire Word process, regardless of whether your computer has 16GB or 64GB of RAM installed. If you regularly handle massive reports with hundreds of pages and high-resolution diagrams, open Word, go to File > Account > About Word. If it displays 32-bit, reinstall Office using the 64-bit architecture to eliminate virtual memory ceilings permanently.
