Disabling Google Chrome Download auto numbering for existing files

When I save a file (e.g. Images) to a folder which already exist there, Chrome adds a (N) where N is first available number.
This causes I have multiple copies of same file!
How can I disable Chrome's auto file renaming?

Thanks

As of now this is not possible but there is a feature request, see discussion here:

The Downloads Overwrite Existing Files extension will overwrite the file if you already have one with the same filename.

Doesn't check if they're the same file contents.

It's not very usable, but there is a way to replace an existing file without installing extensions.
If you just keep the same file name, Chrome will create a new file and auto-number it.

But if you actually click on the target file and click on Save, although the file name is exactly the same, this time Chrome will ask you if you want to replace it:

I tried the above on a Mac, but I have no reason to believe Chrome would behave differently on other OS's (at least in this respect).

This only works when you can select the destination folder, e.g. when you click on "Save Link As..." or enable Ask where to save each file before downloading in Settings.

The Have I Downloaded This Before? extension detects whether a similar download has already been completed and gives you the option to cancel the download and open the existing file. Only works on Linux, so well suited for OP.

The extension that was accepted as the answer no longer exists on the store or Hannos' answer.

I guess this extension might see the same fate.

Here's one that does the same.
