ftp download bug?

[Jungle]

2 times (today and some days ago) while downloading files (> 2Gb) from ftp TC (pb1) stopped downloading with a message "source and target are different". I know that files were not changed. I can't remember such behaviour in e.g. 6.55.

Total Commander 7 now tries to auto-resume a transfer when the connection is lost. TC then sends a REST (restart) command to restart the transfer a bit before the end of the file, and then compares the overlapping part for identity. The error means that something must have corrupted the data near the end of the file.

Can i disable auto-resuming? It's not pleasant to redownload 4Gb file with the 40Kbytes/sec speed.

You may try the following:

Let's say the file you've downloaded so far is 2,934,974,234 bytes. Try to split it using TC to parts of 2,934,900,000 bytes each (just try to delete up to 100K at the end of the file). After that, delete the 2nd part TC-split will create (*.002) and rename the first part to your original file (just replace the .001 extension with the original one). Then try to resume the download to see what happens.

It should work if the downloaded files has been corrupted at the last few bytes only. If you have a poor connection and there is a more extensive corruption then you may have to re-download all of it.

Good luck.

P.S.: Christian, some programs (download managers mainly) have an option to automatically rollback a certain amount of bytes before resuming. I believe TC should have such an option too.

Yes, Configuration - Options - FTP, there is an auto-resume option which you can turn off.
