Description
Dear FileZilla Team!
I've been using FileZilla for several years now, but recently noticed an issue where big files are uploaded corrupted. Few days ago I've been uploading a file (a 7z archive) that is a bit over 2 gigabytes. The upload went without any issues or warnings and file on the server had exactly the same size as the original. Although, when I check md5 checksum - they differ. Then I checked file contents and few bytes in the middle (3 different places) were different.
I have tried the same file again - the same issue, but now different bytes were different. I have tried once again - and yet again same issue. Then I split the archive into 3 parts (files) using archive-split feature, so that each file size is smaller (around 700MB). I have uploaded all three one by one (as opposed to in parallel together). One out of three was uploaded corrupted.
I'm not sure if it helps, but I'm using an insecure FTP Server (meaning, no encryption, but with a password). Transfer mode is set to "Default". Charset is set to "Autodetect".
Please let me know how can I help further diagnose the issue.
Thank you very much in advance!
P.S.: I have found several "corruption-related" issues which are already closed, but did not find anything 7z-related, therefore added a new one. Please let me know if I should have used an older one instead.
