What is the best way to add scripts?

[FTPServerTools]

A small question about the scripts section. Suppose I have a new version of one of my scripts. Suppose my script is stored as FTPLogger.zip and I now upload a new version also as FTPLogger.zip will the old one be overwritten or not?
Should I put the version number in the filename (extra work) to keep the old versions available? I know that in the old script section this had to be done.
Please advise us scripters of the best way to do this.
And if it has to be with version numbers I would suggest to make it so that it can be stored using a normal filename without overwriting an old one...
