Is there a reason why help projects should be located in the hard drive's file structure such that they have particularly short path names? Is seems to me I read that somwhere, and I noticed that our developer put a previous help project right in the root directory. We use the Eclipse IDE and CVS for source control, does that have any bearing?
The location and path length are separate issues. RoboHelp projects must be on the hard drive. Path length is a Windows limitation and it can get too long if your project is in your profile. In addition to the folders and files in the project, they are all prefixed with C:\users\yourname etc.
Maybe it is the output the developer is moving or maybe it is to do with it being picked up by source control. Otherwise I don't know why they would move your source project.

Best practices dictates that RH projects should be located in a C:\Projects\\ folder on your hard drive.
