Final answer:
When the standard information creation timestamp does not match the filename creation timestamp, it means that the two timestamps are different.
Step-by-step explanation:
When the standard information creation timestamp does not match the filename creation timestamp, it means that the two timestamps are different. This can occur when a file is created on one device and then later copied or transferred to another device. The standard information creation timestamp is a record of when the file was first created, while the filename creation timestamp is the date and time associated with the file's name.
For example, if you create a document on your computer and then move it to a USB drive, the standard information creation timestamp will show the original creation date on your computer, while the filename creation timestamp will show the date and time when the file was moved to the USB drive.
