Release lock on file

Question

Hello,
Sometimes, but it is rare, if communication fails when user is uploading a picture file to the server, that the file stays locked.

How can I release the lock on that file so the user can retrieve to upload it?

Here is the exception thrown when user tries to upload a file that is locked on the server:

Using Process Explorer, I can see the file is locked by CompleteFTP process:

I already tried to restart CompleteFTP server using CompleteFTP Manager without success.
 

Comments

If a file gets locked you might need to restart the CompleteFTP service via the Windows service manager. But make sure you are running the latest version of CompleteFTP, as there was a locking bug in earlier versions.

Thank you for the fast answer !
Restart service from Windows service manager did release the lock on the file, great!
For information, I use the last version (13.0.0)
May I close the question?

Sure. But if you could email support your diagnostics.log file with the error we'd like to take a look at it to see how it happened and try to prevent it again. (see C:\ProgramData\Enterprise Distributed Technologies\Complete FTP\Logs)

OK,
I will close the question and send you the log file.

Thank you

We identified a scenario where locking could occur, and released a fix in version 13.0.1. If anyone is experiencing this issue, please upgrade to 13.0.1.
