"An entry with the same key already exists."

I tried to import a SAZ file. I pointed the folder to my 'Downloads' folder, which has many different file types in there. As soon as I clicked next from selecting 'Downloads', I got this error twice. See attached screenshot.

    I wrote about the "Repair" feature here:

    Sorry, to be clear about what's happening here, what exactly did you click when you "tried to import a SAZ file"?

    The "Repair Corrupt" option is available in the dropdown on the File > Load Archive screen. It attempts to repair the corrupt ZIP file so that it is correctly formatted. Fiddler itself generates properly-formatted ZIP files, so if you're seeing this error, it's likely that either the disk is corrupt or the file was transferred over a network link (or USB key) that corrupted its data.

    Thanks Eric. I moved the file to its own folder and I still get this error. Also if I try to open the file directly outside of Fiddler, I get a slightly different message (see attached). It mentions a 'Repair Corrupt' option, but I cannot find it anywhere.

    I'd love to provide the file but unfortunately it potentially contains client information so I don't want to risk sharing it.

    This will happen if you have a ZIP/SAZ file in the folder with an illegal format (e.g. containing two files of the same name and path). Unfortunately, it's unlikely that this can be readily fixed as any workaround would have to be inside the ZIP library built by Xceed software.

    It would still be interesting to get a copy of the file that's causing this; you could drag/drop or file > open the ZIP/SAZ files in that folder until you find the culprit.
