Metadata PNG

Hello everyone

I have used this website:

To view the metadata of PNG file. Is there any software or website that can show more data than the website above?

When Windows gives a PNG file a "stamp" in form of dates (created, accessed, modififed), where in the file is that data stored, and is it accessible?

Could it be possible to view these "dates" in the byte-data, by using FileInputStream?

Looking forward to your answers

This will give you more information, but going further, I'm not sure:

Windows file and folder timestamps are used to correlate events and system activities by time. They are displayed by reading and recording to the NFTS file system. Different file systems and operating systems have different methods of dealing with this data. The information you are looking for "in the PNG file" is most likely, but not always, a file system time stamp.

The write time indicates the last time the file was written to, or last modified date.
The access time is when the file was last accessed for a read or write.
The creation time is when the file was created.

For NTFS, there is consistency. When you move a file from one file system to the other, you can get a creation date that is later than the last modified date.

This information can be modified, but it involves changing the attributes of the file as it relates to both the NTFS volume and Windows. This information can be changed with a freeware program called Smart Timestamp:

About EXIF Timestamps

When you take a photograph with a digital camera or a cellphone camera, there are likely to be timestamps within those files in the form of EXIF data marks. These can even include latitude and longitude coordinates for where the image is taken, if the user is on a cellphone and elected to use that feature. However, the standards seem to be different for each camera. More information on that here:

If this is for casual use, that's one thing. None of this promises your changes wouldn't be detected using proprietary analysis of your system or the given files/hard drives.

On an additional note, this is also a good reason that drivers and such are digitally signed.
