>There must be a maximum, but I think performance is the real limiting factor. Folder access really bogs down when the file count gets up there.

We have folders with several thousands of files. We are just moving up to be able to support up to 60000 files, which will probably not happen, but this is what the client has to upload into a specific directory. Because, once received, a robot will process those files one by one and remove them. But, I just wanted to verify those numbers first. As for a few thousands, it's only a question of waiting longer if you use FTP for example. In that case, if we have to go on disk, we will use Windows Explorer.
