The ‘.fe_tmp’ file extension is a temporary file created by Mi File Explorer, the file manager application pre-installed on many Xiaomi devices. These temporary files hold data during ongoing operations within the app, acting as a sort of scratchpad for tasks like copying, moving, compressing, or extracting files. Because they’re temporary, they’re usually automatically deleted once the operation is complete. However, sometimes due to unexpected app closures or system errors, these files might linger. Don’t worry if you see them; they generally don’t pose a security risk. They simply represent incomplete processes within Mi File Explorer. Trying to manually open them directly is generally unproductive, as their contents are typically unreadable without the context provided by the app. Forcing their deletion might even interfere with ongoing tasks.
If you’re concerned about the number of ‘.fe_tmp’ files accumulating, the best course of action is to simply restart your device. This often clears out any lingering temporary files. Alternatively, you can try closing and reopening Mi File Explorer, which might also resolve the issue. In rare cases, if the problem persists, clearing the app’s cache and data (through your device’s settings) might be necessary, though be aware that this will remove any recently used settings within the app. Remember, these files are inherently temporary and designed to be automatically managed by Mi File Explorer; manual intervention is usually unnecessary.
