Hi Krishnan

Thanks for looking into this.

I have replicated the issue with a file of 6KB

When duplicating some lines to enlarge the file >10KB, the issue did not occur;

About the SFTP server, which is not managed by ourselves, I can see the following information;
- FTP version: SFTP-3
- Cryptographic protocol: SSH-2
- SSH Implementation: AWS_SFTP_1.0
Files I used:

Hi jvandenbranden,

We tested the 'Receive File Over SFTP' with the file (CSV) less than 10 KB size. We can see the exact size of the file(metadata) is updated in the Appian. Also, the file size is updating without any issues while we tested it will the file size greater than 5 MB. Please provide the snapshot of the issue and sample file for testing.

Please find the attachment while we tried to reproduce the issue.
