Sumatra PDF is a PDF, ePub, MOBI, CHM, XPS, DjVu, CBZ, CBR reader for Windows

"Find" command not showing for epub and mobi files

I’m new here but find SumatraPDF the only satisfactory ebook reader on windows systems. When reading an ebook or an article in epub or mobi the FIND command is almost essential. Now there is such a command in the pdf formats but I can’t find this command - ‘Find’ - for epub or mobi. Am I missing something? It would complete the program for me if one was available.
Thanks for a brilliant programme! Phil

This info. should probably be made a sticky thread given how often the question comes up…

No, you’re not missing anything at all. Unfortunately only the FixedPageUI (used for PDFs) displays the toolbar with the Find text field whereas EbookUI lacks this. You can open up Advanced Settings via Hamburger (3 lines) menu > Settings > Advanced Options and change:

EbookUI [
    # if true, the UI used for PDF documents will be used for ebooks as well
    # (enables printing and searching, disables automatic reflow)
    UseFixedPageUI = false
]

to

EbookUI [
    # if true, the UI used for PDF documents will be used for ebooks as well
    # (enables printing and searching, disables automatic reflow)
    UseFixedPageUI = true
]

Close and re-open Sumatra for the modified setting to take effect.

Changing UseFixedPageUI from false to true works also in ChmUI?

Best regards

Why not try it and see? Anyway available settings and explanations are all there in the link I gave above that leads to this page.

Brilliant, many thanks. Phil

Hello
I see nothing can support to find an item we look for in the file we open by Sumatra PDF.
I tried to find or create but nothing is supported.
Please tell me if it possible.

  1. Can you see a toolbar in SumatraPDF? You should see there a search field described as “Find:”, with left and right triangle arrows and button with lower and uppercase letter next to the search field.
  2. You can use menu Go to | Find. Why are you asking about the whole menu? Do you have any problems with navigation using mouse or keyboard?
  3. You can press Ctrl+F - it’s a standard hotkey in Windows programs.

Note that some PDF files or other documents may contain only scanned pages or other pictures with NO text available to find.

Sumatra unfortunately still doesn’t support finding text, copying text etc. in formats such as EPUBs and MOBIs, so if you’re not seeing the Find option in the toolbar (or the toolbar itself for that matter), or under the Hamburger (3 horizontal lines) Menu > Go To or Ctrl+F is not working, then most likely you’ve opened one of these file types and not a PDF.

If you want all these features to work with ebooks as well then you’ll need to change the view to be the same as for PDFs. For this go to Menu > Settings > Advanced Options which will open the SumatraPDF-settings.txt file. In there change:

EbookUI [
	...
	UseFixedPageUI = false
]

to

EbookUI [
	...
	UseFixedPageUI = true
]

Save and close the file, then close and reopen Sumatra to see the changes.

There is a new option in version 3.2 and current pre-release which means less need to edit advanced settings since the most frequently changed one is now on the Debug menu as Toggle ebook UI. Shortcut is ALTDT

Note you may also need to press R to Reload/Refresh the layout
