Issue to open some folders in Documents Library

Hi all,

Today I was facing to a strange issue : users were no more able to open Document Library via the “Open with Explorer” Library Tool option.

But, other libraries were able to be opened via this option, and subfolders of the faulty Library.

The error message was :  ... is not accessible. no permission. You might not have permissions to use this network resource.

I made a search on internet, and found the Sean Wallbridge Site http://www.brainlitter.com/2011/12/05/sharepoint-open-with-explorer-errors-the-parameter-is-incorrect/ with the same issue and a nice solution.

Issue is created (in my case) when the end-user created the folder with 2 space characters next each other.

Doing this make SharePoint replacing the first space by “%20”, but not the second space character.

So, the URL is not correctly rendered, and give the mentioned issue.

I had more than 1000 documents in the faulty library.

And about more than 400 folders to review, one by one.

Result was that only 5 folders were wrongly written with 2 time the space character in their name.

Simply edit the item, and removing the extra space, then save solved all the issues.

So, remember that not only the files can have this issue, but also the folder’s name.

That's all folks.
