Unable to open file after renaming it

Question

I have a recording from jitsi app in my dropbox then after i changed the name of the recording the file won't open anymore ( saying there is an error importing the document from another app )????
Even through the recordings that i did no edit its name is perfectly fine and can be opened . What can i do to get this recording to open

Hey @Elaf, thanks for reaching out to the Dropbox Community!

Can you follow the steps here to rename the file and see if you can open it then?

Elaf · Answer

I have followed the restore of previous version ( thinking i can get back to before i edit the name)
Reached previous versions ( same as current one) i tried to open it and it says " files without extensions cannot be previewed "
I keep pressing the download button but it wont budge .

Note: the app is in my phone do i use dropbox.com for this process?
