Deleted photo video recovery refers to the process of retrieving photos and videos that have been accidentally or intentionally deleted from a device such as a smartphone, or tablet. When a photo or video is deleted from a device, it is usually moved to a temporary storage area called a "trash" or "recycle bin" from where it can be restored if needed. However, once the trash or recycle bin is emptied, or if the photo or video is deleted directly without being moved to the trash or recycle bin, it is considered permanently deleted from the device's file system.

Deleted photo video recovery involves using specialized software or services to scan the device's storage for remnants of deleted photos and videos. This may involve searching for traces of the deleted files in the device's memory or storage sectors and attempting to reconstruct the files based on the remaining data. The success of photo video recovery depends on various factors such as the type of device, the file system in use, the amount of time elapsed since the files were deleted, and whether the storage space has been overwritten with new data.

It's important to note that not all deleted photos and videos can be successfully recovered. If the storage space has been overwritten with new data or if the files have been deleted using specialized software that securely erases data, recovery may not be possible. Additionally, the use of photo video recovery software or services may have legal and ethical considerations, as it may involve accessing potentially private or sensitive data. It's always recommended to use such tools or services in compliance with applicable laws and regulations, and with proper authorization.
