Chrome download changes file extension

Select show advanced settings at the bottom of the page, and scroll down until you find the downloads section. There you can check "ask where to save each file before downloading" to get download prompts in Chrome, and change the default download folder to another location as well. Another issue that you may run into from time to time is that Chrome will change the name of downloaded files if a file of the same name exists already in the download folder. While that is wanted at times, think of two files that have the same name but are different files, it may not be wanted at other times.

It happens for instance when you hit the download button twice, or if the page initiates a download automatically. While Chrome prevents pages from pushing multiple downloads to your system, it won't prevent that if you initiate the downloads manually, or if the downloads are not executed in a short period of time. The Chrome extension Downloads Overwrite Already Existing Files prevents duplicate file downloads in Chrome by overwriting files if they exist in the selected download folder.

So, instead of ending up with duplicate files ending with 1 , 2 and so on, you end up with a single file. The extension will overwrite files with identical names even if the content is not identical. This makes it a rather specialized extension, one that is probably only of use to users who experience issues regularly with duplicate downloads. Another option that you have is to enable download prompts in Chrome.

This gives you flexibility when it comes to duplicate files. Enabling the shelf while at least one other extension has disabled it will return an error through runtime. When any of a DownloadItem 's properties except bytesReceived and estimatedEndTime changes, this event fires with the downloadId and an object containing the properties that changed. This event fires with the DownloadItem object when a download begins. During the filename determination process, extensions will be given the opportunity to override the target DownloadItem.

Each extension may not register more than one listener for this event. Each listener must call suggest exactly once, either synchronously or asynchronously. If the listener calls suggest asynchronously, then it must return true. If the listener neither calls suggest synchronously nor returns true , then suggest will be called automatically. The DownloadItem will not complete until all listeners have called suggest. Listeners may call suggest without any arguments in order to allow the download to use downloadItem.

If more than one extension overrides the filename, then the last extension installed whose listener passes a suggestion object to suggest wins. In order to avoid confusion regarding which extension will win, users should not install extensions that may conflict. If the download is initiated by download and the target filename is known before the MIME type and tentative filename have been determined, pass filename to download instead.
