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.
