You install Internet Information Services (IIS) 8.0 on a computer that is running Windows 8 or Windows Server 2012.
You create an FTP site by using IIS 8.0.
You upload files to the FTP site by using the Ftp.exe utility.
You run the following command to monitor the upload progress of the files: ftp> literal size file name
In this scenario, the command does not return the current size of the file as expected. Additionally, you receive the following error message:
550-The process cannot access the file because it is being used by another process. Win32 error: The process cannot access the file because it is being used by another process. Error details: File system returned an error.
This issue occurs because of a sharing violation that occurs when you use the literal size command to query the current size of a file that is already open with write access.
