Here we will discuss about an issue which we will get if you will provide folder name more than 128 characters in SharePoint on premise or SharePoint online. The error will appear as:
The specified file or folder name is too long. The URL path for all files and folders must be 260 characters or less (and no more than 128 characters for any single file or folder name in the URL). Please type a shorter file or folder name
– SharePoint Online Site Workflow and Initiation Form Parameters example using SharePoint designer workflow
– Introduction to cloud computing and Microsoft Azure
There is a limit of 128 characters for folder names in SharePoint. So the best thing is to give small meaningful names as well as avoid spaces and special characters. For example a space which encoded as %20 will take three characters.
– The file / folder name should not have more than 128 characters.
– The full path of file / folder length should not exceed more than 260 characters.
Hope this will be helpful.
