Hello Mark,

Thank you very much for your code.

It works well if it is the first time you drop only one file. Then it will wait for the next file. -- But unfortunately, it does not work in the subsequent runs, because (I think) the value of "property file_1" stays the same as the first time it had a value.

I am sure this method is better than the other way (which uses the "choose file" dialogue) because with the "choose file" dialogue, the user tends to be not sure of selecting the right file...

Perhaps it would be possible to work around this problem if instead of "property", I write the file_1's path in a temporary file somewhere, and delete it each time the script finish its work. -- Unfortunately, I don't know how to achieve this.

Thank you in advance for any further idea.

Best regard,
