Hi Chris-
When i made a second attempt, i've followed your instruction step by step, but nothing changed.
Files stored on my virtual machine (but not in docker container). Directories, between which i transfer files, both placed in Documents folder.
UPD: Looks like i've troubleshooted all that moments, for now. Issue was in absence of dxlfiletransfer.config files in some folders. But when i read the documentation,I got the impression that actions with the configuration files should be performed once and then i just need to indicate it's location. Thank you for help. Also, i would recommend to add some of your steps to documentation, so it would be easier for less-skilled users to deal with it. For example, Command Line Provisioning pages has no information about provisionconfig command for the sample folder etc.
Thanks for help,
Andrew
