修复: 比较 Documents Not Working in Word

The 问题

Word’s 比较 Documents 功能 isn’t working. You try to go to Review > 比较 > Combine, select two files, but nothing happens or an 错误 appears. The 比较 dialog hangs or closes without creating 比较. You need to see all differences between two versions but Word’s 比较 功能 is broken. Files are incompatible 格式 or the 功能 can’t find them.

Quick 修复

Ensure 两者 documents are saved and closed:

1. 保存 两者 documents you want to 比较: Press Ctrl+S in each
2. 关闭 all Word documents: 文件 > 关闭 All
3. Go to Review tab in ribbon
4. Click 比较 (dropdown arrow next to 比较 button)
5. Select 比较 or Combine (Combine is for merging edits)
6. In the dialog:
   • Original 文档: Browse to your first 文档
   • Revised 文档: Browse to your second 文档
7. Click OK (not “More Options” for now)
8. Wait 10-30 seconds (比较 takes time for large documents)
9. A new 文档 opens showing all differences as tracked changes

If this doesn’t work, proceed to 步骤-by-步骤 解决方案.

步骤-by-步骤 解决方案

步骤 1: 关闭 All 打开 Word Documents

打开 documents interfere with 比较 function.

1. 关闭 all Word documents:
   • 文件 > 关闭 All or 关闭 each individually
2. 验证 Word window is empty
3. Don’t 关闭 Word itself—keep the application 打开
4. Now 打开 比较 function: Review > 比较 > 比较

步骤 2: Choose Correct 文档 Locations

Files must be saved before comparing.

1. In 比较 dialog, click “Original 文档” folder icon
2. Navigate to where your first 文档 is saved
3. Double-click the 文件 to select it (or click once and click “打开”)
4. Important: Don’t 打开 the 文件—just select it
5. The filename 出现在 the “Original 文档” field
6. Now click “Revised 文档” folder icon
7. Navigate to your second 文档
8. Select it the same way
9. 两者 filenames now show in the dialog
10. Click OK

步骤 3: 检查 文件 Compatibility

Documents must be in compatible formats.

1. 两者 files should be:
   • Word documents (.docx, .doc, .docm)
   • Not PDF, not 图像, not other 格式
2. 验证 文件 extensions:
   • Right-click each 文件 > Properties
   • 检查 the “Type” field
   • 两者 should say “Microsoft Word 文档” or similar
3. If one is PDF:
   • You can’t 比较 directly to PDF
   • Convert PDF to Word first (special tools required)
   • Or use alternative 比较 method (步骤 10)

步骤 4: 验证 Files Are Not 打开 or Locked

Files in use can’t be compared.

1. 检查 if documents are 打开:
   • If they are, 关闭 them (文件 > 关闭)
   • Don’t 保存 if you don’t want to
2. 检查 if files are locked by another user:
   • Right-click the 文件
   • If read-only or locked icon appears, wait for other user to 关闭
3. Try 比较 again once files are closed

步骤 5: 保存 Unsaved Documents First

Unsaved documents can’t be compared reliably.

1. If you want to 比较 an 未保存的文档:
   • 保存 it first: Ctrl+S or 文件 > 保存
   • Give it a filename
   • Choose a location
   • Click 保存
2. Repeat for the second 文档
3. 关闭 两者 documents
4. Now try 比较 again with the saved versions

步骤 6: Use 文件 Path if Documents Won’t Select

Sometimes 文件 browser doesn’t show documents.

1. In 比较 dialog, instead of using folder browser
2. Right-click in the “Original 文档” field
3. Paste 文档 path if you have it
4. Or type the full path: C:\Users\YourName\Documents\Document1.docx
5. Do same for “Revised 文档”
6. Click OK

步骤 7: Try Combine Instead of 比较

Combine is sometimes more reliable.

1. Go to Review > 比较 > Combine (instead of 比较)
2. Combine is designed for merging edits from multiple reviewers
3. Select documents same as 比较
4. Combine shows differences but is optimized for merging tracked changes
5. Some users find Combine works when 比较 fails

步骤 8: 启用 More Options If Basic 比较 Fails

Advanced options can 帮助 with difficult documents.

1. 打开 比较 dialog: Review > 比较 > 比较
2. Select documents as usual
3. Before clicking OK, click “More Options” or “Show More Options” (bottom left)
4. Additional settings appear:
   • Ignore formatting: Checks only 文本, not formatting changes
   • Ignore spacing: Ignores space/tab differences
   • Ignore punctuation: Ignores punctuation changes
5. Uncheck options that aren’t relevant (focus on actual differences)
6. Click OK
7. 比较 might now succeed

步骤 9: 比较 Documents in Different Order

Sometimes order matters.

1. If 比较 fails, try reversing which 文件 is “Original” and which is “Revised”
2. Swap them and try again
3. This occasionally fixes strange errors
4. Result shows differences either way, just direction might differ

步骤 10: Use Alternative 比较 Method

If Word 比较 absolutely won’t work:

1. Manual side-by-side view:
   • 打开 两者 documents
   • Go to View > View Side by Side
   • Scroll through and manually note differences
2. Use Word Online 比较:
   • Upload 两者 documents to SharePoint
   • Use SharePoint web interface > 比较 versions
3. Export to Google Docs and 比较:
   • Convert 两者 to Google Docs
   • Google Docs has built-in 比较
4. Use third-party 比较 工具:
   • DeltaView, Diff utilities, or similar
   • These often work when Word 比较 fails

步骤 11: Repair Office if 比较 Persistently Fails

比较 功能 might be corrupted.

1. Go to Control Panel > Programs > Programs and Features
2. Find Microsoft Office
3. Click Change
4. Select Quick Repair
5. Wait for completion (2-5 minutes)
6. If 比较 still fails, repeat and select Online Repair
7. Online Repair rebuilds all Office components
8. Try 比较 again

Why This Happens

1. Documents still 打开 — 打开 documents interfere with 比较
2. 文件 not saved — Unsaved documents can’t be compared
3. Incompatible 格式 — One 文件 is PDF, 图像, or non-Word 格式
4. 文件 locked by another user — 文件 in use prevents 比较
5. Corrupted 文档 — One or 两者 files have internal corruption
6. 比较 功能 bug — Older Office versions have 比较 bugs
7. Path or filename issues — Special characters or very long paths break 文件 selection
8. Insufficient disk space — 比较 creates temporary files; needs space

如何 Prevent It

1. 保存 两者 documents first — Never 比较 unsaved files
2. 关闭 documents before comparing — Don’t 比较 打开 files
3. 验证 compatible 格式 — 两者 must be .docx, .doc, or .docm
4. Use meaningful filenames — Avoid special characters in filenames
5. Keep Office updated — Updates 修复 比较 bugs
6. Test 比较 early — Don’t wait until critical moment
7. Maintain backup copies — Keep originals before making changes
8. Use 版本 control — For extensive revisions, use Track Changes instead of 比较

Still Not Working? Alternative Solutions

1. Side-by-side view — View > View Side by Side shows 两者 documents at once
2. Track Changes approach — Instead of 比较, use Track Changes on one 文档
3. Google Docs 比较 — Upload to Google Docs, use their 比较 功能
4. Diff/patch tools — Command-行 tools like diff (Windows/Mac) for comparing 文本
5. Visual 比较 software — Beyond 比较, Araxis Merge, or WinDiff
6. Manual 行-by-行 review — 打开 两者 documents, read each 行 carefully
7. Reinstall Office — Complete 卸载 and fresh 安装
8. Contact Microsoft 支持 — For persistent 功能 failures

Key Takeaways

• 关闭 all documents before comparing (don’t 比较 打开 files)
• 保存 两者 documents first (unsaved files can’t be compared)

• Use Review > 比较 > 比较 to select documents
• 比较 creates new 文档 with tracked changes showing all differences
• Combine is optimized for merging edits from multiple reviewers
• Use View > View Side by Side as alternative to 比较
• If 比较 fails repeatedly, reinstall Office or use third-party 比较 tools
