If you are dealing with files on your filesystem in your flow, time to time you may encounter this error. If you are moving a file, copying a file or trying to unarchive a zip file.
The first thing you should check is, of course check the path on your filesystem. If everything looks correct, this path may be hiding a non-visible character, that probably comes from a copy-paste operation.
So that if you copy paste this error message into a hex-editor you may see those unvisible characters as below:
"opening source file: open <U+202A>C:\Users\01\Downloads\534834-REPORT-20220127-123.zip: The filename, directory name, or volume label syntax is incorrect."
If you fix the path by deleting these characters manually, your flow should start working fine.
