File Miner - Data Recovery

Review by eFreeware

File Miner is a free Android recovery tool from RichMobile Life, published on Google Play since June 2022 and sitting in the Productivity category. It has two jobs: hunting down files that have gone missing from your phone's storage, and giving you a place to keep the files you would rather not lose. The developer describes it as a way to find files tucked away in places you would not think to look and pull them back before the operating system or another app wipes them for good.

That framing is what makes it worth a second look. Most people only think about file recovery after the fact, when a photo has vanished from the gallery or a document has disappeared from a folder. An app built around that exact problem, rather than around general file management, is a narrower and more useful thing. File Miner is free to install, which lowers the cost of keeping it around for the moment you need it.

Who tends to need a recovery tool

The clearest fit is anyone who has deleted something on their phone and wants it back. Photos and videos are the usual casualties, since a misjudged tap in the gallery can remove a shot before you have had a chance to back it up. File Miner is built to scan for those items and let you preview them before deciding what to bring back, which matters when a scan turns up more than you expected.

Documents are the other obvious case. If a report, a downloaded form or a saved PDF has gone missing, the app's recognition of common document formats is meant to help surface it. People who handle a lot of files on their phone, whether for work or study, are the ones most likely to notice the difference between a recovery tool and simply giving up on the file.

The vault feature points to a second group: people who want a fixed place for files they consider important. Rather than relying on a folder that another app might clean up, they can park those items somewhere the developer describes as harder to delete by accident. Anyone who has lost a file twice tends to appreciate that kind of insurance.

What the deep scan actually looks at

The headline capability is a deep scan that reaches into hidden folders along with cache and temporary directories. These are the corners of Android storage where deleted content often lingers for a while before it is overwritten or cleared out. A scan that only checked the obvious locations would miss a lot; widening the search is the point of the feature, and it is the reason the app exists at all.

The developer pairs that scan with smart file recognition. Common document, photo, video and audio formats are identified during the search, so the results are organized around the kinds of files people actually want back rather than a raw list of storage addresses. That should make the difference between a scan you can act on and one you have to decipher.

It is worth being realistic about what any recovery tool can do, and running a scan sooner rather than later is the sensible approach.

Previewing, recovering and exporting

Before anything is restored, File Miner lets you preview the deleted photos, videos and audio it has found and choose which ones to bring back. That selection step is the part I would value most, because recovering everything a scan turns up is rarely what anyone wants. Being able to look first and decide second keeps the process manageable.

Once items are recovered, the app lets you view them and supports exporting to external public directories. That gives you a way to move recovered content out of the app's own space and into somewhere you can reach with a file manager or another app. For photos and videos in particular, getting them back into a normal, accessible location is usually the whole goal.

The file vault handles the preventive side. Important files placed there are described as not easily deleted, which is a different promise from recovery: instead of chasing lost data, you keep the things that matter out of harm's way in the first place. Used alongside the scan, it covers both the accident and the aftermath.

What it costs and what comes with it

File Miner is free to download and the developer calls it completely free. There are no in-app purchases, so nothing inside the app is gated behind a payment. That is a straightforward arrangement, and it means the decision to try it costs you nothing but the install.

The app does contain ads. That is the trade the developer has made: no charge and no purchases, with ads present instead. I would set expectations accordingly rather than treat it as a hidden catch.

The developer also asks for a five-star review if the app works for you and offers a contact route for questions, promising to respond as soon as possible. The most recent update, from late September 2026, mentions process optimization and fixes for known bugs, which suggests the app is still being worked on rather than left as it was at launch.

How it compares with the alternatives

The nearest alternative is your phone's own file manager. Those tools are good at showing what is there and moving it around, but they are not built to search for content that has already been deleted, and they do not offer a vault. If your problem is organization, a file manager covers it; if your problem is something that has vanished, it usually cannot help.

Cloud backup services are the other comparison. They solve data loss by keeping a copy elsewhere, which is a stronger guarantee than recovery, but only for files that were uploaded before the loss happened. File Miner works on what is already on the device, so the two approaches address different moments: one prevents the loss, the other tries to undo it.

There are also general-purpose cleaner and optimizer apps that promise to free up space. Those tend to remove files rather than find them, which is close to the opposite of what File Miner does. A dedicated recovery tool sits in its own niche, and that narrowness is a fair description of both its strength and its scope.

A recovery tool worth keeping installed

File Miner does one job with a clear method: scan deep, recognize the file types people care about, let you preview and choose, then recover and export what you picked, with a vault for the files you want to protect. It is free, it carries ads, and it asks nothing else of you. For a 50 million-plus install base and a 3.9 average from over 38,000 ratings, that combination has clearly found an audience.

I would suggest it to anyone who has deleted a photo, video, audio clip or document on Android and wants a shot at getting it back, and to anyone who would rather keep important files in a place that resists accidental deletion. Install it before you need it, since the sooner a scan runs after a loss, the better the odds. If your aim is general file organization or cloud backup, that is a different task and a different tool.
