Upload and Download Your Files at the Maximum Speed Possible

TCP/IP protocol limitations make it challenging for a single application to fully saturate a network connection.

However, S3 Browser Pro enables you to upload and download files using your network connection at full speed!


How it Works for a Large Number of Small Files:

Pro Version

Multiple small files are uploading at the same time

The Pro version allows you to upload and download multiple files at the same time.

Multiple files are uploaded/downloaded simultaneously. Each TCP connection operates at full speed. In total, you get the speed you're paying for!

Free Version

Free version is limited up to two simultaneous uploads

The Free version is limited to two simultaneous uploads.

Only two files are uploaded or downloaded simultaneously. The Free version supports up to two concurrent uploads or downloads. For example, if your upload speed is 2 Mb, each connection might be limited by the protocol to approximately 256 Kb. In this case, you are only utilizing 512 Kb out of your 2 Mb available speed.

Only two files are allowed at a time

How it Works for Large Files:

Recently, Amazon S3 introduced a new multipart upload feature.

Large files can be split into smaller parts and uploaded in parallel. If the upload of a part fails, you can simply restart it. You can improve your overall upload speed by taking advantage of parallelism.

The multipart upload feature is enabled by default in both S3 Browser Free and Pro versions. All files larger than 5 MB are uploaded via multiple parts in parallel.

The multipart download feature is also supported by both S3 Browser Free and Pro versions! However, as you already know, the Free version is limited to two simultaneous transfers.
