Answer 1

Here you can find which file names are allowed.

The following characters are not allowed:

• < (less than)

• (greater than)

• : (colon)
• " (double quote)
• / (forward slash)
• \ (backslash)
• | (vertical bar or pipe)
• ? (question mark)

• * (asterisk)

• Integer value zero, sometimes referred to as the ASCII NUL character.

• Characters whose integer representations are in the range from 1 through 31, except for alternate data streams where these characters are allowed. For more information about file streams, see File Streams.
• Any other character that the target file system does not allow.
