Remove your temporary files!

During the program run of an application, it is sometimes unavoidable to create temporary files (e.g., in the Temp system directory), which may be needed until the program is closed. However, removing these temporary files at the latest when closing the program is a recommended good practice for many reasons. Here is a method to conveniently manage temporary files automatically:

First, declare a StringList Field variable in your Form class (it should be a public variable if you plan to use it in other forms of your application too):

Then create the StringList in the OnCreate event handler (of your main form):

Whenever you create a temporary file during the program execution, you should not forget to add it to this list of temporary files, for example:

Then, when the program terminates (preferably in the OnDestroy event handler of your main form), the collected temporary files are automatically deleted, and the allocated StringList object is removed from the memory:

That's how easy it is to manage your temporary files!
