Keyword searching can be an effective way to identify data on a device, depending on the circumstances. If you know exactly what you're looking for and have a good understanding of the naming conventions and file types used on the device, keyword searching can quickly locate relevant files.
However, if you're not sure what you're looking for, or the files you're searching for have been renamed or stored in unexpected locations, keyword searching may not be the best approach. In these cases, it may be more effective to use specialized search tools or data recovery software that can scan the device's file system and identify relevant files based on file type or content.
Additionally, if the data on the device has been encrypted or otherwise secured, keyword searching may not be an effective way to access the data. In these cases, you would need to use specialized decryption tools or techniques to access the data.
