Add multiple files one by one in an array
Seems trivial. What have you tried?
In a proper state machine, the code will not "stop", just proceed to another state, e.g. for the "other purpose", or to an idle state waiting for the next command. So you want an automatic prompt for each file? When should the adding of file stop? (E.g. if the file dialog is canceled?)
I'd pop up a dialog VI that has a cluster array of a Boolean and a FileName. Tick the ones you want, press OK and it filters those out and continue.
A few more ideas:
- The file dialog has an option to select multiple items (uncheck "limit selection to single item"). Once the dialog pops up, you can ctrl-click as many files as you want and you'll get an array of paths out. No need for looping.
- Have a control for a folder and pattern and populate a listbox with all matching file names. Now you can select multiple items or e.g. toggle a checkmark symbol by double-clicking. (e.g. similar to what I use here)
I would stay away from repetitive file dialogs, because they make it difficult to see what has already been picked, for example.

Just last thing, the chosen files are going into array in alphabetic order rather than in the order I am clicking them. I want the file to go at the top of the array which is clicked first in the folder and vice versa.
You can use a multicolumn listbox (similar to already suggested) and display a sequence number with every click in the second column, then sort entries by that value at the end. (Of course you need mechanisms to undo and edit later, e.g. if you accidentally clicked in the wrong order. You should also add some sanity checks to prevent entering the same path twice.
