Microsoft Admits to Zip File Bug, Assures Its No Big Deal While a Fix is Planned for November

Microsoft Admits to Zip File Bug, Assures Its No Big Deal While a Fix is Planned for November

Microsoft hasn’t had a lot of luck with its Windows 10 1809 feature release. New bugs continue to pop-up, keeping the company from finalizing the update and releasing it publicly. One of those is an issue reported that overwrites destination files when copying them from a compressed zip file. According to Microsoft, a bug does exist here, just not in the way it’s being represented. While there is a problem with a missing warning dialog box to overwrite files, they aren’t really being overwritten anyway.

In a new thread in the Microsoft forums

With the Windows 10 October 2018 Update, if you copy or move files from a .ZIP file (without first “extracting” the contents) into a new destination folder that contains duplicate filenames or is write-protected, you don’t get a “Do you want to replace these files” prompt. It will appear that the files were overwritten, when in fact the copy action for those files is not executed and files have not been overwritten.

In the thread, the forum moderator gives guidance on how to use zip files in Windows 10 and how to recover files that are accidentally overwritten if zip file procedures aren’t performed correctly.

Microsoft is working on a resolution and estimates a solution will be available in early November for this issue.
