We do maintenance on a lot of web sites we inherit from other developers.
Often, there is a need to change something in the Flash file(s).
Normally, only the swf files are located on the web server. To get the .fla file requires the cooperation of the prior developer, not always easy for the obvious reasons. In some cases, we have had to rebuild the fla from scratch.
Is there any downside to including the .fla file(s) on the web server as well so the next developer can easily get at them?
