FileFluss

Manage your files across cloud storage providers without getting complicated. I had seen an application like this for Windows before, but I hadn’t found any for Mac. Its main advantage was unifying different cloud storage services so you could use them as a single storage unit. For example, if you had 10 Gmail accounts offering 15 GB each, the tool would take whatever you uploaded, split it, and distribute it across all those accounts to create a single pool. Let’s check out this trick to get it for free.

Introducing FileFluss

I am pleased to announce a second project called FileFluss, a cloud file manager. Look, it provides a comparison mentioning great solutions like Transmit or Free File Sync. That was the one I was talking about. Hold on, we have something interesting here… I don’t understand this language [laughs], but I assume the first option is to accept, even though it’s in German. Let’s enable translation here because we haven’t learned German yet. It is an optimized application designed to conveniently access data from various cloud storage providers and copy, move, or rename files—even directly from one cloud to another. Very cool.

How File Transfer and Chunking Work

The supported services allow effortless file copying and transfers. If I recall correctly, what the other software did was take a 1 GB file, split it into smaller chunks—much like a torrent file—and distribute those fragments like peers across your connected cloud services. When requested back, the application knew exactly which service stored each missing segment, downloaded them simultaneously, stitched them together, and delivered the complete file to you. Essentially, a torrent system built on top of cloud services.

This enabled you to take advantage of free tier accounts. You could sign up for free accounts across multiple services, and the app would seamlessly combine them. For the user, the experience remained unchanged: you drop the file in, the app stores it, and retrieves it just like using Google Drive. You see it in Drive, but Google handles distributing it across their backend servers without exposing that complexity.

Integrated Services and Features

Currently, it integrates with various cloud storage providers: pCloud, aDrive, koffer, OneDrive, Google Drive, Dropbox, Nextcloud, and Mega. The list is continuously expanding. I remember that following my Free File Sync video, many viewers asked about support for other providers like Terabox.

It features a clear search functionality across all connected cloud accounts and local drives. Once you search, it shows the exact location of the file across each service (Dropbox, Gmail, Google Drive, etc.). It would be great if the app automatically chunked and distributed files; implementing this shouldn’t be too complex since it only requires generating an index manifest (like a torrent file) and assigning fragments to destinations. It also displays download and upload speeds after completing file operations. It includes a folder synchronization mode between services (mirror mode), a directory comparison tool, and a sync engine.

Developer and Interface First Impressions

Developed by Robert Rudolph, a one-person project. It’s an application with solid potential. We are looking at GitHub release version 1.0.1, a very recent build. FileFluss, FileFluss.

Visually, it operates as a standard dual-pane file explorer. It lets you toggle hidden files, refresh both panels, copy, drag-and-drop, move, and compare directories.

Local Folder Synchronization

I tested local synchronization by creating two folders on the desktop, temporal and temporal 2. When running a left-to-right sync, the app calculates missing files, copies them over, and keeps both sides in sync. This demonstrates that it isn’t limited to cloud services—you can also use it to sync local directories directly on your Mac.

Unlike a simple manual copy-and-replace—where deleting a file in the source folder leaves the old file untouched in the destination—proper synchronization ensures the backup target matches the source state perfectly.

Account Setup and Dropbox Testing

The About section includes a donation link to support project development. Under general settings, you can toggle hidden files, deletion confirmation, and cloud service integrations.

To test cloud functionality, I added two separate Dropbox accounts inside FileFluss. I set the account containing the test file on the left panel and the empty account on the right panel. Running sync left to right calculated the space, downloaded the file, and synchronized it between both Dropbox accounts seamlessly.

Storage Limit Handling and Final Thoughts

A great feature addition would be the ability to automatically split large files across accounts when encountering quota limits. When uploading a file that exceeds a basic 2 GB tier, the application attempts the upload until the cloud provider rejects it due to insufficient space. Having an integrated visual indicator showing remaining account storage would be very helpful. For now, storage management must be monitored manually, but the application performs reliably.

In summary, FileFluss is a very solid tool. I will post the download links and testing details in the testing section on my website. For each tool, I publish a card containing the download link, video test, category, and my honest conclusion on what worked well and what could be improved. My goal is to maintain a practical, easy-to-access repository of tested software for everyone.
