Savefile creation date?

[marcocip]

I retrieved different files I did during years.
Different version of same project, files modified by third parties...
It could really help me to rebuild what's happened to start from checking the file creation date.
That is not possible from the information released by the OS about each file, because if for example the file was copied to a new USB key, the "date of the copy" became at same time the "date of the creation" and the "date of the last modify".
I hoped to find a creation date inside a "file info" option in a menù inside the SH3D, but I was not able to find such an option.
Maybe someone could hint me on how to retrieve the real "creation date" looking inside each file?

If not handle by the system, the creation date isn’t stored in a SH3D file.
