Unable to transfer files with % (Percent sign) in the file name

[thetonyleone]

I am transferring a large number of files from a windows server to a QNAP SFTP server.

I have had no issues with almost 1 TB of data over the SFTP until it started error out.

I am getting an error that says Cannot write file Error time out. It started happening more and I found the %(percent sign) in the files names was the cause. If I click ignore on the error it might resume or sometimes it just seems to crash and not move forward on any further files. I de-selected the directory where the percent signs were located and the transfer was able to keep going without issues.

I am working to find files with the % in them but its hard searching when its 130000 files left.

I have also tried this with temp files turned on and off, ignore errors on, and auto retry on with the same error. I finally just had to exclude that directory where I found some % files named.

Looks like a QNAP bug. Copying files with percent sign works fine on other SFTP servers.

Even with ignore errors on? Shouldn't it just skip those files?
