• TobyRickett Accessing the FTP root directory.

  Hi, I'm working on a class that walks the directory on an FTP server. It looks for files following a certain format (i.e. "Acc*"), and returns the directory in which the files are located. The servers have limited scope, and access is limited to only a few users, so it is certain that only one folder will contain these files. This needs to be done with little to no user intervention.
