# How do I resolve the "InvalidPathException-Trailing char < >" error from the AWS Snowball client when I transfer files on my Windows machine?

### Issue

I'm trying to transfer files to an AWS Snowball device using the Snowball client on my Windows workstation. However, I get the error "InvalidPathException-Trailing char < >". How can I fix this?

### Resolution

To resolve the "InvalidPathException-Trailing char < >" error, you must remove trailing spaces from the names of the files that you're trying to transfer. For more information on Windows file-naming conventions, see Naming Files, Paths, and Namespaces.

To remove trailing spaces, you can run this command in Windows PowerShell:

Get-ChildItem -recurse "* .*" -Path “path\to\directory” | Rename-Item –NewName { \$_.name –Replace '\ \.','.' }

Note: This command removes one trailing space for each file name. If your file names have multiple trailing spaces, run the command multiple times until all trailing spaces are removed.
