Resuming large download help please

Hello,

I was in the middle of transferring a 5gb file when my wireless connection went.
I had transferred roughly around 67%.
I am posting the log as well with this as it may or may not help here.

The ftp client keeps retying and then telling me the timestamp of the retry, i.e. retry at 2.21.32 etc.
The problem is that this is not resuming, and i'm not sure what the 'default' action is for large single files here.
I have gone through the settings, and re-checked transfers after re-connection (i.e. started a different download) and there is no problem there, so I need help please..

Please post the log from the transfer. Double click the file in the transfer queue window to get it.

log file is long gone now so maybe you could tell me how to make sure that the program automatically splits one large file into chunks for transport?

SmartFTP automatically resumes broken transfers. There shouldn't be any problem if your wireless connections goes down in the middle of the transfer.
