No More Duplicates - Avoid Duplicate File Downloads

"No More Duplicates" is a handy Chrome extension that ensures you don't download duplicate files. When you initiate a download, it checks for the file's existence on your hard drive. If the file exists you can either download it regardless or open the extant file. It's a simple but elegant solution to prevent unnecessary file duplication, saving you storage space and bandwidth.

User reviews

Brilliant extension that stops me from downloading the same pdf twice. Chrome says it is no longer approved and suggests some absolutely different alternatives? Only reason to use Chrome is the wide range of extensions!

very well

If for some reason you delete a file from your downloads folder, this extension won't take that into account and will still say "this file has already been downloaded", even though it hasn't.
