Sorry for the translation, I speak French.
I’m not sure I’m in the right place
To make a copy of a file in the drive
(and read with google_drive [Wiki ubuntu-fr])
by opening ‘text.odt’ with LibreOffice for example and then doing ‘save as’, it is renamed (a bit like this ‘1I_UA_wyRQ…7dltXzsm’)
In a similar way, when you attach a 1.PDF file from the drive in Thunderbird, it is renamed (something like this ‘1I_UA_wyRQ…7dltXzsm’), which is also very annoying?
