Appending data to downloads after resume

[cyberduck]

39ed8ec created the issue

A download was stopped due to line problems. Upon resuming I ended up with a file double the size as original. luckily 7Zip could still decompress.

I reported this 8 years ago and it was ignored as you couldn't repeat the problem as if it didn't existed. It still exists. Back then it was the OS X version. Now here it is the Windows Version.

Often Zip files get corrupted if I use the resume function. Other FTP programs do resumes reliably. Transfer on Mac and FileZilla on Mac/PC

Now after stopping and resuming on one file several times Cyberduck sits at 100% and never finishes nor downloads more. download size matches file size. I sit with an .czberducksegment file.

upon next resume it downloads a few megabytes (like 5) and I get an error:

Interoperablity failure: 554 /filename: invalid REST argument. Please contact your web hosting service provider for assistance.

It then shows 427.5 KiB of 0 B.
