Does cancelTransfer() deletes current file ?

Question

hi,

I use java Thread to trigger ftp file transfers. i want to be able to cancel the transfer by user pressing a cancel button.

for this i call the FTPClient.cancelTransfer() method. it seems to work because when i checked file size after cancel it is less than total file size.
the problem is that i want to be able to delete the current canceled file when i call cancellTransfer(). does this method take care of that ?
logically it should.but i noticed the file remains in ftp server with incomplete size & it is tedious for me to track which file is canceled to delete it afterward.
any suggestion to deal with this issue is greatly welcomed.

thanks.

Answer 1

If you call cancelTransfer(), it stops the current transfer where it is up to. It does not delete the partially transferred file. Call delete() to do that.

Answer 2

thanks.

if i cancel a ftp upload i can delete the partially uploaded file .(indeed i had to quit() & reconnect before being able to delete ftp file).

however i'm facing a hard time to do same with file download:
if i cancel ftp download & try to delete partial file on local drive the File.delete() method fails.
it seems some other process (may bejavaw.ee or the Thread i use for download) is locking the file.
before calling File.delete() i call Thread.interrupt() to stop download thread i also set my thread object to null and call System.gc() .but still unable to delete the partial downloaded file.

can you help me fix this annoying issue ?

thanks much.

Answer 6

thanks ,i solved the issue .
it was Thread.interrupt() method which didn't release the lock.
so i used another flag technique to terminate the Thread and exit run() method.
