hi all,

i've done a little prog. to change creation time attribute of files.
During creation time changing i would like to set a flag in the file, to recognize that the creation date has been already changed and is not original.

some1 know a way to do it ?

If it is an executable file leave a signature consisting of nop instructions.

perhaps by writing something in a reserved section of the FAT/NTFS ?

In that case, if you take the file to other computer you would not know it was modified.

If you mean for any file, generally... then no. Well, perhaps set the
seconds to some predefined value, but I dunno if that's too useful.

If you only need to do this for your own files, nothing stops you from
putting a "hasFileBeenModified" flag somewhere in your file data.

In text files you can add a space ASCII character.

Yes, i know, it is not the better solution, and also it will increment the file 1 byte.

Let me ask you a question: What are you coding? You are not creating some kind of "badware", are you?

On NTFS you can write some info into the NTFS streams :)

Thanks all.


nice idea :) I think i will use your suggestion: a combination of msec and sec will recognize a not original file.


i'm a good boy. The idea of this file creation time alignment was suggested from my desk-job-neighbour: he sais that could be useful a prog. to align creation time just to release a software product with all the files created at same day/time. Just for an order reason, the day of release will be equal for all the files. Attached my prog, just look if can be useful...

Bye B7
