Remote servers will likely prohibit certain characters from being used in file and folder names. If you see issues with invalid file or folder names, we recommend you modify those names to remove the restricted characters.

Remote servers may also restrict the length of the file or folder name. Common length limits include:

• 160 characters
• 255 characters

Each type of Remote server will calculate the total filename length using its own method. Some remote servers calculate the total length as being either just the file or folder name, including any extension OR the sum of the whole folder path + file name + extension + temporary suffix

If your syncs are failing with invalid file or folder names, shorten the name of files and folders so that they are below the length limits of the remote server.

The maximum allowed path length on Files.com is 550 characters for the length of the full path, including folder names.
