We are looking for a Version Control System to change our current Source Safe one. We are using it along with Visual Studio. We've failed so far - and the main reason for it is that all the alternatives we see doesn't support one or more features of VSS, especially one that we use widely - file share! What's up with that?
Alternatives like Source Gear claim to support them, but I gotta tell you that they do that very poorly. Not to mention that they are way slower than Source Safe, and have even more bugs.
What alternatives we do have to source version systems that do support file share? Or is there a reason to not use features like this? Please share your experience and support your comments.
EDIT:
By Share File I mean that I can checkout a file from any project that is sharing it, do some changes and then all get the latest version. It is very useful when working with C++ projects, or even C# Web Projects. I want to be able to share a file without the need to make another library for that.
From MSDN:
Sharing Files or Projects
Visual SourceSafe has a Share command that allows sharing of files or projects. For use of the command, see How to: Share an Item.
When you request file sharing, Visual SourceSafe creates a shared link between the versions of the file in the projects that share the file. When you check in the file to one of the projects, your changes are automatically checked in to all the sharing projects. All the projects that share a specific file are listed in the Links tab for the file.
When you share a Visual SourceSafe project, you create a completely new duplicate project under the current project. All the files in the new project are shared with the corresponding file copies in the shared project, and changes in one are reflected in the other during check-ins to the Visual SourceSafe database.
Other tools do have similar concepts, though not always with the same name or exactly the same semantics. Off the top of my head:
I tend to avoid them because it indicates there are some other issues with my project. If the resources are needed across many projects, I package them as a library and set my other projects to depend upon that artifact (using a dependency management tool such as Maven or Ivy to manage the dependencies)
