I have a problem with the UPLOAD function of SYNC. The ftp server I am connecting to is running on MSDOS and will not accept the long filenames with the .part added extension. (this is what I deduct from the server output with default SETUPLOADMODE)

When switching to DIRECT UPLOADMODE it tries to overwrite the file with the direct filename, but then it sounds: error: File already exists.

Here is the feeback (VERBOSE(ON))
Default "SETUPLOADMODE":

I am now considering to bypass this by using the below code, but I would prefer SYNC:

[ScriptFTP]GETLIST
GETFILETIME(LOCAL)
GETFILETIME(REMOTE)
IF $BLA > $BLABLA
DELETEFILE
PUTFILE
END IF[/ScriptFTP]

Thank you for your advice!

Hello Jonas,

Thanks for posting here. I modified the script you posted but I think it will not work as good as SYNC. The problem is that it does not handle the clock time difference that may exist between the the computer where ScriptFTP is running and the FTP server.
FTP Script
  1. # Get the file listing
  2.  
  3. GETLIST($list,LOCAL_FILES)
  4.  
  5. # For each remote file
  6.  
  7. FOREACH $file IN $list
  8.     $localfile_time = GETFILETIME(LOCAL,$file)
  9.     $remotefile_time = GETFILETIME(REMOTE,$file)
  10.     IF($localfile_time > $remotefile_time)
  11.         DELETEFILE($file)
  12.         PUTFILE($file)
  13.     END IF
Another way that might work is comparing the file sizes. If you are sure that in your case a newer file always implies a different file size you can use this one:
FTP Script
  1. # Get the file listing
  2.  
  3. GETLIST($list,LOCAL_FILES)
  4.  
  5. # For each remote file
  6.  
  7. FOREACH $file IN $list
  8.     $localfile_size = GETFILESIZE(LOCAL,$file)
  9.     $remotefile_size = GETFILESIZE(REMOTE,$file)
  10.     IF($localfile_size != $remotefile_size)
  11.         DELETEFILE($file)
  12.         PUTFILE($file)
  13.     END IF
I noticed the problem of time difference indeed. I fixed it by making a timesync, but is is only 99%.

I will let it run on filesize for a while to see where it goes.

EDIT: The FTP server won't accept the SIZE command, so I am back to the time for now. The fault is with the ftp server.

Thanks!
Jonas
Thanks for the update Jonas
