#converted ebooks showing up as .bin files instead of .EPUB

I converted an ebook I purchased to an EPUB using calibre and then sent it to my phone. When I tried to import it into the jidoujisho, it failed and gave me a message saying it can only accept htmlz or epub files. When I look at the file browser on my phone, the file extension for the ebook is a .epub but my phone sorts it as a .bin file and doesn't categorize it as a text file like it does with my other .epubs. I was able to get the book working by converting to htmlz instead of epub but I would still like to know why the epub format isn't working.

It is named .EPUB

The epub on the bottom is this month's book club book

#

The one on top is the epub I tried to import

#

What's also interesting is that the epub on the bottom is labelled as a txt type file by my phone while the epub I made doesn't have any label

Hi, where did you name this files?

What operating systems normally do is to hide the extension, as the average user don’t want or need them (or rename the file and break it)
This is visible on the first file on the screenshot - the file ending is always the ending (makes sense) - for you it’s „.epub (1)“ - the actual file may be „.epub (1).bin“ (or whatever), in the second case it is probably „.epub.txt“

You can fix this in windows by going to a directory, searching for the options button, and disabling the option „hide known file extensions“ - on Android I have no idea how, and on iOS I needed like 30 minutes with research and shit…

I recommend it in general, as it increases safety against malicious files (ever heard of .png.exe or .pdf.exe? You would not see the .exe and click shit… old, but still works today)

however

#

this is what the same file looks like on my desktop

#

in win 11

#

the name was autogenerated in calibre i'm assuming based off interpreting the kanji charactes as mandarin

Mhm… in the previous screenshot there seems to be another ending in both files - the first with the (1) at the end would be an invalid file ending, the second is shown as .txt

wicked spade
#

the (1) is because the first thing i tried was downloading it again to my phone

#

i figured maybe i sent the wrong file since calibre generates multiple files when you convert

grim oak
#

Yes. But the 1 would be before the file ending. So what you’re seeing is not the actual file ending

wicked spade
#

so i need to check if android automatically changed the file extension to .bin

#

btw i sent the file to my phone by email

grim oak
#

So it would be „my ebook (1).epub“, but it’s „my ebook.epub (1)“, so in reality it’s „my ebook.epub (1).wedontknowyet“ (I’m just assuming they are ebooks)

#

the most recent screenshot was from when i downloaded the same attachment in that email onto my desktop

Can you try uploading it to your google drive directly and syncing it to the phone? Some providers do stuff because they a) thing it’s a potential virus or b) think they have the right to do everything

wicked spade
#

hmmm these do seem to be file extensions

#

like they're all correct for every file i have downloaded

#

also when i scrolled down to the first download, as in the one that doesn't have .epub (1), the OS does correctly identify it as a txt file type

#

In the screenshot it looked like it was synced to google drive

wicked spade
#

there's something that comes with my phone but i don't have it on my pc

#

or will it just work with my email

grim oak
#

I can try help out tomorrow, if necessary per discord call and screen sharing if you’re comfortable. For now I wouldn’t know how to remote troubleshoot this case

#

I can only say that I’m near confident that it’s a file ending issue on your phone

wicked spade
#

not sure if it was the root cause or a coincidence but when i bought the next volume in the series just now it imported onto my phone without issues

#

i also used google drive to download it instead of attaching it in an email
