name starting with dot – so called dot files), because user does not need to see them normally. Normally Finder does not display some files (e.g. Finder with hidden files displayed: search internet for “Show hidden files in Finder”.Let’s meet our new friends which will help us: This case looks very appealing for a curious man who wonders: “How is it done”? So we will later explain some basic methods. In later runs it usually displays how many days still you can use it. When the application is run for the first time, a dialog appears with the information that the application is not registered and you have some time to try and explore it.
Another method which is more comfortable for user is that the application stores silently the information about start of the trial period somewhere in the computer.Example of such an application: Araxis Merge. The application doesn’t work without the code. The code contains information about start or end date of the trial and has some redundancy (checksum), so it is not easy to fake the date. The application is informed from outside – the most common is probably registration process when you enter your email address on the developer’s page and an email is sent to you with some code you enter into the application.I haven’t met any software which uses this type of starting of the trial period. Moreover technically speaking such a trial is measured from installation date, which may differ from the first usage date (preinstalled computers). There are several timestamps on a file, but each of them can be changed by the system (if you copy files, the new files may have the same timestamps as the original file). This method is a bit pointless, because there is nothing such a “creation date” of a file. The applications look onto “creation” date of its binary (or other) files, for example.If it does, anything is possible, so I won’t to analyse this case.

So let’s think how to tell the application the start date of the trial period:

When you download and install the software with trial time, the application (software) must get know, when the trial period started and wether the trial period is finished.
