Is there limitation for maximum number of files which can be uploaded in SharePoint location in one folder.

Question

1. Is there limitation for maximum number of files which can be uploaded in SharePoint location in one folder.
2. Is there limitation for maximum number of folders/sub folders which can be created in SharePoint location.
3. Whether specific naming convention is required to be followed for folder/file creation in SharePoint(Special character allowed)?

Answer 1

For #1: The maximum library limit is 30,000,000 documents. The maximum practical limit for a single folder is 2000 files. Sharepoint does not scale well beyond 1000 files per folder.

For #2: There's no practical limit for the number of subfolders. Your folder structure will become unmanageable well before you reach the limit. The complete URL for the file or folder cannot be longer than 260 characters. Note that this includes the server, site and library name.

For #3: You cannot use the following characters anywhere in a folder name or a server name:
~ # % & * { } \ : < > ? / | "

File names and folder names cannot be longer than 128 characters.
