Reading Time: 3 minutes

For authors, seeing your own book on a Kindle screen is a milestone. It’s the moment your manuscript stops feeling like a document and starts feeling like a real book. But getting your own book onto your own Kindle — especially a Kindle Fire (affiliate link – As an Amazon Associate I earn from qualifying purchases.) — can be surprisingly confusing if you’ve never done it before.

Fortunately, with Calibre, the process becomes simple, predictable, and completely under your control. Here’s the author‑friendly guide to preparing, converting, and loading your book onto a Kindle device using Calibre — plus the one piece of hardware that can make or break the entire process.

Why Use Calibre?

Calibre is the Swiss Army knife of ebook tools. Authors use it because it lets you:

  • Convert manuscripts into Kindle‑friendly formats
  • Embed metadata and covers
  • Test formatting before uploading to KDP
  • Produce clean AZW3 files for sideloading
  • Keep a library of your own works

It’s free, powerful, and ideal for authors who want full control over how their book appears on a Kindle. Download Calibre here.

Step 1: Export Your Manuscript to EPUB

Start with a clean EPUB file. Whether you write in Word, Scrivener, Vellum, or Google Docs, exporting to EPUB gives Calibre the best foundation to work with.

Step 2: Import the EPUB into Calibre

Open Calibre and click:

Add books → Select your EPUB

Your manuscript now appears in your Calibre library, ready for conversion.

Step 3: Convert the EPUB to AZW3

AZW3 is the best format for Kindle Fire devices because it preserves:

  • Fonts
  • Spacing
  • Images
  • Table of contents
  • Reflow behaviour

In Calibre:

  1. Right‑click your book
  2. Choose Convert books
  3. Set Output format = AZW3
  4. Adjust margins, fonts, or metadata if needed
  5. Click OK

Calibre generates a clean AZW3 file inside its internal book folder.

Step 4: Connect Your Kindle — With the Right Cable

This is the step that trips up most authors.

Not all USB cables transfer data.

Many USB‑C cables — especially the ones bundled with chargers — are charge‑only. They power your Kindle but do not allow file transfer.

When you plug in a Kindle Fire with a charge‑only cable, Windows shows:

“This folder is empty.”

Even if the device is unlocked.

The fix is simple:

✔ Use a proper data‑capable USB cable

Amazon link to USB data cables (affiliate link) – choose one suited to your Kindle – newer ones take USB-C. Mine is older and takes a USB-Micro at one end.

Once you switch to a real data cable, Windows immediately reveals the Kindle’s internal storage:

  • Internal storage
  • Books
  • Documents
  • Download
  • Pictures

Now you’re ready to sideload.

Step 5: Copy the AZW3 File to the Kindle

In Windows Explorer:

  1. Open Fire → Internal storage → Books
  2. Copy your .azw3 file into the Books folder

That’s it. The Kindle Fire will detect the file automatically.

Step 6: Open the Book on Your Kindle

On the Kindle Fire:

  1. Open the Kindle app
  2. Go to Library
  3. Tap Downloaded or All

Your book appears within seconds.

This lets you preview:

  • Typography
  • Chapter breaks
  • Image handling
  • TOC behaviour
  • Overall reading experience

Exactly as your readers will see it.

A Note About Performance

Sideloaded AZW3 files work beautifully, but they behave slightly differently from Amazon‑delivered books:

  • Page Flip is disabled
  • Navigation may be slower
  • The Kindle treats it as a “personal document”

This is normal. If you want the full Kindle experience (including Page Flip), you can still email the EPUB to your Send‑to‑Kindle address — but Calibre remains the best tool for preparing the file.

Where to find your Kindle email address

On a Kindle Fire:

Settings → Your Account → Send‑to‑Kindle Email

Or on Amazon:

Account & Lists → Manage Your Content and Devices → Preferences → Personal Document Settings

This address accepts EPUB attachments and delivers them straight to your Kindle library.

Summary

With Calibre, the process is straightforward:

  1. Export to EPUB
  2. Convert to AZW3
  3. Use a proper data cable
  4. Copy the file into the Kindle’s Books folder
  5. Preview your book like a reader

Once you’ve done it once, you’ll wonder why you didn’t start sooner. It’s one of the most satisfying parts of the publishing journey — seeing your own words on the same device your readers will hold.

Search Inside a PDF in File Explorer

A practical guide to fixing PDF content search on Windows using TET PDF IFilter

If you’ve ever tried to search inside a folder full of PDFs using Windows File Explorer, you’ve probably run into this maddening scenario:

  • You type content:keyword
  • Windows returns nothing
  • But when you open the PDF, the word is right there
  • Your PDF viewer (PDFgear, PDF‑XChange, Foxit) finds it instantly
  • Windows Search acts like the word doesn’t exist

This is not your imagination. It’s how Windows Search actually works — and why you need the right PDF iFilter.

This post explains:

  • Why Windows Search often fails to find text inside PDFs
  • Why your PDF viewer can find words Windows cannot
  • How to fix the problem permanently using TET PDF IFilter
  • When you need to re‑OCR PDFs
  • How to avoid re‑OCRing hundreds of files manually

1. Why Windows Search can’t find text inside many PDFs

Windows Search does not read the visible text on a PDF page.

It only indexes the hidden text layer inside the PDF — the layer created by OCR or embedded fonts.

This means:

  • If the PDF is a scan
  • If the OCR layer is missing
  • If the OCR layer is corrupted
  • If the OCR layer contains mis‑recognised characters
  • If the PDF uses weird embedded fonts
  • If only some pages were OCR’d

…then Windows Search will not find the word, even though you can see it.

Example from real life

A PDF titled How Bombay Was Ceded contains the author name:

J. H. GENSE

PDFgear finds “Gense” instantly.

Windows Search (content:gense) finds nothing.

Why?

Because the title page has no OCR text layer. The word “Gense” exists only visually — not in the text layer Windows indexes.

2. Why PDF viewers can find text Windows Search cannot

PDF viewers like PDFgear, Foxit, and PDF‑XChange use visual text extraction:

  • They search the rendered glyphs on the page
  • They don’t rely on the hidden OCR layer
  • They can find text even when the PDF’s internal text layer is broken

Windows Search cannot do this.

It only indexes what the PDF’s iFilter gives it — and if the iFilter sees nothing, Windows sees nothing.

3. The fix: Install a proper PDF iFilter (TET PDF IFilter)

Windows needs a PDF iFilter to read inside PDFs.

Adobe Reader used to provide one, but I don’t want Adobe on my system — and modern Windows versions don’t include a reliable PDF iFilter by default.

The best non‑Adobe solution:

TET PDF IFilter (PDFlib)

  • Free for personal use (old version 5.4)
  • 64‑bit native
  • Fast and accurate
  • Works with Windows Search indexing
  • No Adobe components required
  • Ideal for large collections of historical or scanned PDFs

Once installed, Windows Search can finally index PDF contents properly.

4. How to enable PDF content indexing

After installing TET:

  1. Open Control Panel → Indexing Options
  2. Click Advanced
  3. Go to File Types
  4. Scroll to .pdf
  5. Ensure it says: Filter Description: TET PDF IFilter
  6. Select Index Properties and File Contents
  7. Rebuild the index (optional but recommended)

Now Windows Search can read inside PDFs — if the text layer exists.

5. Why some PDFs still won’t index (even with TET installed)

If a PDF has no text layer, Windows Search still cannot index it.

This is common in:

  • DjVu → PDF conversions
  • Old scanned books
  • Microfilm scans
  • PDFs with partial OCR
  • PDFs with broken embedded fonts
  • PDFs where only some pages were OCR’d

In these cases, Windows Search will only find:

  • Words in the filename
  • Words in the metadata
  • Words in pages that do have a text layer

But not words that exist only visually.

6. How to fix PDFs with missing or broken text layers

You have three options:

A. Re‑OCR the PDF

This regenerates a clean text layer.

PDFgear can do this, but doing it manually for 200+ files is painful.

B. Batch‑OCR everything automatically

Use a tool like:

  • OCRmyPDF (free, open‑source)
  • ABBYY FineReader PDF (paid, industrial‑strength)

These tools can process entire folders unattended.

C. Use a search tool that ignores the text layer

If you don’t want to fix the PDFs:

  • PDF‑XChange Editor
  • DocFetcher
  • Recoll

These tools search the rendered text, not the OCR layer.

7. When to add folders to the Windows index

If you want instant search results:

  • Add your PDF folders to Indexing Options → Modify

If you don’t:

  • Windows will still search them, but it will do a live scan
  • This is slower but works fine for occasional searches

8. Summary: The reliable workflow

Here’s the practical, repeatable setup:

✔ Install TET PDF IFilter

This gives Windows the ability to read PDF contents.

✔ Ensure .pdf is set to “Index Properties and File Contents”

This enables content indexing.

✔ Add your PDF folders to the Windows index (optional)

This makes searches instant.

✔ Re‑OCR only the PDFs that matter

Or batch‑OCR everything once.

✔ Use PDFgear/PDF‑XChange for visual searches

These tools can find text Windows cannot.

9. The bottom line

Windows Search is powerful — but only when paired with a proper PDF iFilter and clean text layers.

If a PDF contains text visually but not in its OCR layer, Windows Search will never find it. TET PDF IFilter fixes the indexing side. OCR fixes the PDF side.

Once both are in place, content:keyword becomes a reliable, fast way to search inside thousands of PDFs.

Restoring the Voice of Rajabai Tower: Why Mumbai Should Bring Back Its Carillon

India No Comments
Reading Time: 3 minutes

The Rajabai Clock Tower is one of Mumbai’s most beloved landmarks –  a soaring Victorian Gothic spire rising above the Oval Maidan, its silhouette etched into the city’s collective memory. Completed in November 1878 after nearly nine years of construction, the tower was formally inaugurated on 27 February 1880 by Governor Sir Richard Temple. Designed by Sir George Gilbert Scott, who modelled it on London’s Big Ben, the tower was funded by philanthropist Premchand Roychand, founder of the Bombay Stock Exchange, who named it after his mother, Rajabai. At 280 feet (85 metres) and costing ₹547,703, it was the tallest and most expensive structure of its kind in Bombay.

Today, the Rajabai Tower is part of the UNESCO World Heritage–listed Victorian Gothic and Art Deco Ensemble of Mumbai. But one of its most remarkable features—the musical carillon—has long fallen silent.

A Victorian Engineering Marvel

When the tower was completed, it housed one of the most sophisticated clock‑and‑chime systems in Asia. The sixteen bells were cast by John Taylor & Co. of Loughborough, one of the world’s most respected bell foundries. The chiming mechanism and clock were manufactured by Lund & Blockley, the prestigious London clockmakers who maintained a Bombay branch on Rampart Row.

The bells were arranged in two tiers, suspended on massive iron wheels. The hour bell alone weighed three tons. A compact wooden pin barrel—an ingenious Victorian mechanism studded with brass pins – triggered hammers to strike the bells in perfect sequence. This allowed the tower to play sixteen full melodies, automatically rotating through them at set intervals.

Lund and Blockley also made smaller carillons for the clock towers at the Kolhapur Palace and Custom House, Mandvi (Gujarat).

The Original 16 Tunes Once Played by the Rajabai Tower

These were the melodies performed during the tower’s public inauguration in the early 1880s:

  • A Sinfonia by Handel
  • Those Evening Bells
  • When the Rosy Dawn
  • Luther’s Hymn
  • Hanover (hymn tune)
  • God Save the Queen
  • The Harp That Once in Tara’s Hall
  • St. Bride’s (hymn tune)
  • The Blue Bells of Scotland
  • My Lodging Is on the Cold Ground
  • The March of the Men of Harlech
  • The Last Rose of Summer
  • Rule Britannia
  • Home, Sweet Home
  • The Harmonious Blacksmith
  • Auld Lang Syne

These melodies once drifted across the Oval Maidan, giving Bombay a soundscape unlike any other city in India.

Why These Tunes Are No Longer Appropriate

The original repertoire was entirely British and European—patriotic songs, hymns, and popular airs of the Victorian era. In colonial Bombay, this was intentional: the tower was meant to project imperial prestige.

But in independent India, melodies such as Rule Britannia or God Save the Queen no longer reflect national identity. The silence of the carillon today is partly due to mechanical decline, but partly because the original musical programme is culturally outdated.

A restored carillon should honour the tower’s history while embracing India’s own musical heritage.

What Could a Modern Indian Carillon Play?

A sensitive, heritage‑appropriate repertoire might include instrumental arrangements of:

  • Jana Gana Mana (national anthem)
  • Saare Jahaan Se Achha
  • Vande Mataram (instrumental refrain only)
  • Vaishnava Jana To
  • Raghupati Raghav Raja Ram

These melodies are dignified, recognisable, and suitable for bell arrangements.

Why Restore the Carillon?

Restoring the Rajabai Tower’s carillon would:

  • revive a unique piece of India’s sonic heritage
  • reconnect Mumbai with its Victorian engineering legacy
  • transform the tower from a silent monument into a living heritage experience
  • create a cultural attraction comparable to European clock towers
  • honour both the tower’s colonial origins and India’s post‑independence identity

The Rajabai Tower was designed not only to be seen, but to be heard. Bringing back its music—updated for modern India—would restore the tower’s full meaning and return a lost voice to Mumbai’s historic skyline.
