For the typical cloud user, one in every ten photos is a copy of another. That's not an exaggeration: when we analyze Cloudiet users' folders before compression, the space taken up by duplicates regularly runs into gigabytes. In one test cloud with 32,000 files, the deduplication engine found 127 groups of identical photos — 348 redundant files consuming 2.1 GB. Let's break down where these copies come from, how to find them, and — most importantly — how to delete them without accidentally removing the only copy of a shot.
Where Duplicates Come From: Five Common Sources
Auto-upload from two devices (a phone and a tablet both syncing the same shoot), forwarding through messaging apps (something saved from WhatsApp ends up in auto-upload as a second copy), manually copying folders "just in case," restoring from old phone backups, and editing (the original and the edited version sitting side by side). Each source alone produces dozens of files; together, they add up to gigabytes.
Why Eyeballing It Is Useless
Copies rarely sit next to each other: one is in "Camera," another in "Downloads," a third in a folder called "Vacation 2023 - to sort." Filenames differ too: IMG_4021.jpg and photo_2023-08-14.jpg may be the exact same shot. That's why reliable deduplication compares file content — checksums — not names. This is how all trustworthy tools work, including ours: two files are considered copies only when their content matches byte for byte, which means no false positives.
The Golden Rule of Safe Deletion
Exactly one file must remain from each group of identical files — and that should be the tool's guarantee, not your vigilance. That's how Cloudiet is built: the service never deletes every copy in a group, even if you ask it to; before deletion it shows you exactly what will be removed and what will remain; and deleted files go to the cloud's trash, from which they can be restored for several more days.
Step by Step: Clean Your Cloud of Duplicates in 10 Minutes
Connect Yandex Disk or Mail.ru Cloud in your Cloudiet dashboard, run a duplicate scan on the folder you want (or your entire drive), review the report — how many groups were found and how much space the redundant copies take up — then confirm the cleanup. After that, it's worth compressing the remaining photos right away. How that works and how much space it frees up is covered in our article on compressing photos without quality loss. Together, these two steps typically recover 30–50% of your cloud storage.
Frequently Asked Questions
What if photos look similar but aren't identical — like a burst series?
Burst frames are different files, and we deliberately leave them untouched: choosing the best shot from a burst is a creative decision that can't be delegated to an algorithm. Only exact copies are deleted.
Can duplicates across different clouds be found?
The scan works within a single cloud. On the Pro and Unlimited plans you can connect Yandex Disk and Mail.ru Cloud at the same time and scan each one in turn.
Is it free?
Duplicate scanning and safe deletion are available on the Light plan and above; on the free plan you can gauge the scale of the problem — how much space copies are consuming.
Run a free scan — in a few minutes you'll see the exact number of gigabytes that duplicates are eating up in your cloud.
