File name, length and character restrictions for SharePoint

What are the file name restrictions of the document libraries, link lists, etc? It’s not really a question that I get regularly, but when it comes up I’ll have to look for it as I don’t know it from the top of my head. Here’s a list of general restrictions.

  • File and folder name lengths can’t exceed 128 characters in both WSS 2.0 as WSS 3.0
  • Link list items can’t exceed 256 characters
  • The entire path of files can’t exceed 260 characters

File and folder name restrictions:

  • Can’t be longer than 128 characters
  • Can’t use: ~ # % & * { } \ : < > ? / + | ”
  • Can’t use the period character consecutively in the middle of a file name (blah…blah.docx)
  • Can’t use the period character at the end of a file name
  • Can’t use the period character at the start of a file name
  • Can’t end with:
    • .files
    • _files
    • -Dateien
    • _fichiers
    • _bestanden
    • _file
    • _archivos
    • -filer
    • _tiedostot
    • _pliki
    • _soubory
    • _elemei
    • _ficheiros
    • _arquivos
    • _dosyalar
    • _datoteke
    • _fitxers
    • _failid
    • _fails
    • _bylos
    • _fajlovi
    • _fitxategiak

The same goes for site, subsite and site group names.

There are a couple more restrictions like size, but that’s quite dependent on the server configuration. You can check this blog post for more information about that.

  1. What is the maximum length of the comment field for files in SharePoint Server 2007?

    It is below 1023 – which is the displayed max length.

    • I think that you’re adding to the article, or are you asking that as a question?

      A multi line text field is Defined in sharepoint as a ‘Note’ type, this is stored in the the DB as a ntext sql type.

      The SQL type can store 2gb of char data, that’s 1,073,741,823 characters. This is of course not practical in a webbased environment. However I’m not sure if there’s a built in limit defined in SharePoint.

  2. Hello
    You can also use Long Path Tool to sort out this problem.
