Illegal Characters Scanning Utility

We are preparing to upload a lot of company data to SharePoint online.

We know there are characters which are not permitted in folders and file names such as the ampersand (&). Is there a utility which we can run on the local data which will provide output of all the folders / files which will not be compliant and in an ideal world make changes?

If you try to upload folders / files which have illegal characters to SharePoint online, does it simply stop you or produce a report at the end?

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

The list of characters is not that big, if you remove the ones not allowed on NTFS filesystem anyway:

To list such files, you can use PowerShell:

Get-ChildItem C:\ -Force -Recurse | ? {$_.Name -match "&|\#|~|%|\{|}|\+"}

Open in new window

A quick way to list the names, replacing any invalid characters with space:

Get-ChildItem C:\ -Force -Recurse | ? {$_.Name -match "&|\#|~|%|\{|}|\+"} | foreach { $name = $_.Name -replace '&|\#|~|%|\{|}|\+',' '; echo $Name}

Open in new window
