Cloud Shared Storage Limitations


SharePoint Cloud Storage has some caveats. And is not meant for all files and uses.  There are best practices related to how you name your files and which files should be used from the cloud and which shouldn’t.


File Naming

When uploading documents and folders into Shared Storage locations, certain characters can’t be used. Examples of characters to avoid are ~ " # % & * : < > ? / \ { | }.


File Types

Some files don’t lend themselves to be used from SharePoint or OneDrive.  Large files especially, if lauched without downloading them to your local computer first, can cause a desktop to react very slowly.

File types to be avoided include:

  • Any files that contain High Risk Data.

  • Any files over 250 GB in size.

  • Access Databases.

  • Outlook backup files.

  • Video editing files (like those used in Adobe Premier Pro).

  • OneNote Notebooks as they have their own sync features.

Caution should be used in the following situations:

  • Files that have links in them to other documents that reference the S: drive UNTIL the links have been updated.
  • Storing files from non-Microsoft applications without rigorous testing.
