By right clicking on a file and accessing its properties we can discover a lot of interesting information: its creation date, the date of the last time it was opened or modified and much more. Well, perhaps not everyone knows it but it is possible to modify some of these properties in an arbitrary way, effectively disguising the actual creation or modification dates of a file. It is not a very correct operation from an ethical point of view - this must be said - but in some cases it can be useful, and so I'm here today to explain how to do it.
If you want to know how to change file creation date, all you have to do is take a few minutes of free time and follow my instructions. Below you will find some applications, and some terminal commands, which allow you to change the creation date and / or modification date of a file in an extremely easy and fast way. Contraindications? Virtually none. The contents of the files are not altered in any way and the modified date appears on all operating systems.
Speaking of operating systems: in the tutorial you are about to read you will find instructions valid for both Windows and macOS. This means that regardless of the computer and system you use you will certainly succeed in your intent. Another thing to underline is that the information relating to the creation date of the file, if it is sent via the Internet, for example, are not always kept. To preserve the creation date of a file, it is a good idea to zip it before sending it on the Internet. That said, happy reading and have fun!

Change File Creation Date on Mac
I use a Poppy? In this case you can change the creation and last modification date of a file by simply using the Terminal. This means that you don't have to install third-party applications and you can do everything very quickly. The only problem is that you cannot set dates later than today as the creation date. For the last modification date, however, there is no problem, you can also use future dates. All clear? Well, then I'd say we can take action.
To change the creation date of a file, open the terminal macOS by selecting its icon from the folder Other of the Launchpad. Then type the touch command -t YYYYMMDDhhmm put one empty space, drag the icon of the file you want to change the creation date into the Terminal and press Submit per salvare i Cambiomenti.
The formatting of the touch command -t YYYYMMDDhhmm expects that instead of YYYY, MM e GG there are the year, month, and day of the creation date you want to set for the file and instead of hh e mm the time expressed in hours and minutes.
For example, to change the creation date of a file by setting it to theJanuary 1 1989 you have to use the touch command -t 198901010800 /filepath/filename.xyz. It is important to put a space between the date and the file path.
Using the command touch -t the creation date and the last modification date of a file are changed at the same time. To modify only the last modification date of a file leaving the creation date intact, use the command touch -mt (the formatting to be used for the date and path of the file to be modified remains the same as explained above).
After the modification, to find out if the creation and / or modification date of a file has actually been changed, click on the icon of the file in question and press the key combination cmd+i on the Mac keyboard to call up the window with the properties of the selected object. The creation and last modification dates can be found in the field General of the window that opens.
If you want, you can also change the creation or last modification date of all files in a folder. To perform this operation, all you have to do is use the commands above by entering the path of a folder instead of a file at the end of the command (eg touch -t 198901010800 / path /). To speed up the operation I suggest you type the command touch -t o touch -mt, the creation or modification date to be applied to the files in the folder and to copy the folder icon directly into the Terminal window (leaving a blank space between the date and the path).
Finally, I would like to point out that by using the touch command -t YYYYMMDDhhmm /path/*.xyz or the touch command -mt YYYYMMDDhhmm /path/*.xyz you can change the creation or modification date of all the files of a certain type present in the same folder (instead of xyz you have to type the extension of the file type you intend to modify, eg. touch -t YYYYMMDDhhmm /path/*.pdf to modify only the creation date of PDF files). Easy, right?
