Change Timestamp is a free utility software developed by OGA that allows you to manipulate the time and date on your files. This program is easy to use and does exactly what its name suggests - it can change the timestamp of any file. With Change Timestamp, you can easily modify the date and time when a file was last accessed or modified. It supports batch processing and the drag-and-drop function, making it convenient for handling multiple files. However, it lacks advanced features and the ability to select files by browsing directories within the program. Overall, Change Timestamp is a recommended tool for those who need to automatically change metadata on their files.
