Edit online

Describes any limitations that currently exist for Aspera transfer server and client products.

  • Path Limit: The maximum number of characters that can be included in any pathname is 512 on Windows and 4096 on Unix-based platforms.
  • Illegal Characters: Avoid the following characters in filenames: / \ " : ' ? > < & * |.
  • Environment Variables: The total size for environment variables depends on your operating system and transfer session. Aspera recommends that each environment variable value should not exceed 4096 characters.
  • Usernames with "@" symbol: You cannot add a username with an "@" symbol through the Aspera GUI. You can, however, perform the following actions: (1) Set up a Hot Folder to sync with a Linux server using a Linux account containing the "@" symbol; and (2) Connect to and start a transfer with a Linux server through the Aspera GUI with user credentials containing the "@" symbol.
