JOE should not delete all files on FTP server before saving a hot folder

Current Situation

When editing a hot folder and saving changes on an FTP server then JOE performs the following steps:

• Copy the hot folder from remote directory to local directory
• Working with the local copy
  • deleting and creating new files takes place in the local directory
• When saving
  • all files in the FTP hot folder will be deleted
  • then the local copy will be transferred to the FTP server

The problem is that JobScheduler considers the objects as new objects when more than 2 seconds pass between deleting and saving, e.g. a job chain node will loose its skipped state, jobs will loose their stopped state etc.

Another problem is that probably addes objects from other sources also will be deleted.

Desired Behaviour

• JOE should not delete all files availabe from the directory when saving a hot folder. Instead, JOE should delete individual files that are replaced.
