Had doc on Word-tfd to Writer & saved as odt. USB opens in Word.

Had a document in Word - I opened it in Writer and saved as Writer document. I made corrections and transferred document to a USB. I tried to open the document on the USB adaptor (to check that everything was ok) - it (document) opens up as Word document. When I checked extension on document (on USB) it had the “odt ext” but document only opens in Word program (on the USB) How can I open the document on the USB to be a Writer document and not show up as a Word document? Help!

What is “tfd”, “trfd”, “ck”?

Remember that many of us are not native English readers. If “trfd” and al. seem obvious in your local slang, this is not the case every where. Please use standard English.

Read these guidelines and ask a good question. In particular, pay attention to the section on the language.

It is English - they are short forms - “tfd” means transferred; ck means check; doc means document; ext. means extension

also trfd means transferred also

Please also add information as per comment of @gabix above. E.g., operating system is essential in this case, because, e.g., on Windows, the file associations are not bound to the file placement, but are system- and user-specific. On macOS, on the other hand, there’s a mechanism to tell which files in which placement are opened by which application. (And both LibreOffice and Word are available on both Windows and macOS.)

am using Windows 10

also when I originally saved the document it had the .odt extension and also on the USB - but it only opens in Word

When you have several application on your Windows system that are all able to handle the same file type (distinguished by extension), like several media players all capable of handling .MKV, or several office suites capable of handling .ODT, then only one of them can be associated with the extension - i.e., made the default application that opens when you double-click a file with that extension. It doesn’t matter which application was used for creation of the document; or which application handles the file type “natively”; it only matters which application is registered in Windows Registry to handle that file type. Often, this association happens when an application is installed; sometimes, when it is updated, or even simply run.

All you need to do is to re-associate the file type with the application of your choice. Just right-click an ODT file in Explorer, and choose Properties; and in the opened Properties dialog, click the Change button next to Application: MS Word (or whatever wording is there), and then choose LibreOffice if you want it to handle those types.

And be prepared that it’s possible that this could need to be repeated sometime later, because MS Office is known to quietly re-associate itself with file types, as mentioned in different questions on this site.

tk u for yr help.
