2. Keep files portable and organized

• Create a single folder for KchmViewer Portable and subfolders for CHM libraries (e.g., /KchmViewerPortable/CHMs).
• Use descriptive filenames and include version/date in the filename when collecting manuals to avoid confusion.

3. Improve startup speed

• Avoid loading very large CHM collections at once. Open files individually as needed.
• On Windows, disable antivirus real-time scanning for the KchmViewer folder if you trust the files (or add an exclusion) to reduce launch delays.

4. Optimize viewing and navigation

• Use the table-of-contents and index panels for quick jumps; press F9/F12 (or check View menu) to toggle panels.
• Use the search box to find text within the CHM; try exact phrases or unique keywords for faster results.
• Use Back/Forward buttons and History to move between recently viewed pages.

5. Improve readability

• Zoom in/out with the View menu or Ctrl+Plus / Ctrl+Minus.
• If fonts or rendering look off on high-DPI displays, enable scaling in your OS or use a higher zoom level.
• For complex pages, open the CHM in an external browser by exporting the HTML (if supported) or extracting files with a CHM extractor.

6. Handle encoding and display issues

• If you see garbled text for non-Latin languages, try switching rendering engines in settings (if available) or open the CHM on a system with matching locale fonts installed.
• Install necessary language packs or fonts on Windows/Linux to ensure correct characters display.

7. Use bookmarking and annotations

• Use bookmarks/favorites to mark frequently referenced pages for quick access.
• If you need notes, keep a simple text file alongside the CHM library or use a separate note-taking app—KchmViewer’s built-in annotation features are limited.

8. Extract and convert CHM contents

• When you need to reuse content, extract CHM files with a CHM extractor tool (e.g., 7-Zip on Windows, chmlib utilities on Linux) to get HTML and resources.
• Convert to PDF if you need a fixed-layout document for printing—use command-line tools or GUI converters after extraction.

9. Run on Linux with better integration

• For desktop integration, place a .desktop file in ~/.local/share/applications pointing to the AppImage or binary so the app appears in your launcher.
• Associate .chm files with KchmViewer via your file manager’s “Open With” settings.

10. Backup and sync your library

• Keep backups of critical CHM files using cloud sync (Dropbox, Nextcloud) or simple file copies.
• When using multiple machines, store your CHMs in a synced folder so the portable viewer on each device opens the same library.

11. Troubleshooting quick fixes

• If KchmViewer won’t open a CHM: check file integrity, try another CHM reader, or extract then open HTML.
• If search/index fails: rebuild the index if the option exists or re-add the CHM to the app.
• If AppImage won’t run: ensure execute permission and that required libraries are installed on your distro.

12. Security reminders

• Treat CHM files from untrusted sources cautiously; they may contain scripts or links. Open in an isolated environment if you’re unsure.
