I downloaded a PDF file, but unfortunately the download was interrupted when I already got 43 of 44 MiB. I didn't want to download it again, and the browser was not smart enough to resume the download.
I tried to recover the data inside the almost complete file using the advice from this question: How can I fix/repair a corrupted PDF file?. But no success. Then I downloaded a Windows tool called PDF Fixer and installed it on my Ubuntu system with Wine.
After an eternity this tool came up with a preview window that showed some file content. The tool created a folder called FixedPDFs. It contained the repaired broken file and a small file with "_xref_fixed" in the name. The first still couldn't be opened, the second when opened had only a blank page.
Now how can I get a valid pdf from the content in the 2 files?
