I'm unable to see file's original date it was created in Windows. CS sets the create date as the current date after upload process.
I'm writing a small program that upload files with it's metadata taken from Windows. I'm using this code :

Even though I filled all the fileAtts properties and sent it with the UploadContent() function the result at the CS can be seen like this :

This is how the original file's metadata looks :

This is how the file properties looks when I upload it manually using the add document at CS :

I only able to see the modified date as "created" while created left unknown.
Is there a way to insert the file's original creation date into the properties at cs?
