App

Thunderbird for Android

App version

18.0

Where did you get the app from?

F-Droid

Android version

16.0 - LineageOS

Device model

No response

Steps to reproduce

1. Write a new email
2. Attach more than 1 file (for example 3 files with the same extension type: text_1.txt, text_2.txt, text_3.txt)
3. Write your subject and body content
4. Send it to yourself
5. Once received, open it and click on the attachments button "View all"
6. Your three files will be listed at the bottom popup that appears. Click on "Save all"
7. Select a folder destination and save them
8. Now open your folder explorer and check the three files... all three are the same (same size, same content). Thunderbird saved correctly the third one, but the first and the second file are just a copy of the third one (renamed).

Expected behavior

I expect to save all my attachments with the original content

Actual behavior

Thunderbird corrupts attachments files when you download more than two files using the option "Save all".

But if I download them individually (not clicking on "Save all") the files keep the original content and works as expected.

I have the same problem; also newest app version (18.0) on android 16 (samsung). Multiple different attachment files (in my case it was images) will arbitrarily turn into one of the attachments. But the filenames of the copies will be the same as the original ones shown in the mail.
