I am having an issue renaming a file in SharePoint 2010 whose current url path exceeds 256 characters. There is no custom coding involved here, just a simple rename through the SharePoint UI. I know about the many url limitations within SharePoint (i.e. 260 full file path, 128 file/folder name, etc.). However, this issue does not appear to be one of those limitations.
Here is a sample url: "/PaulsTestSite/ASubSiteWithinPaulsTestSite/SubsiteToTestRename/Document Library To Test Rename of File/This is a Sub Folder/Another SubFolder To Test Rename/One Last Sub Folder to Test Rename/aaaaaaaaaaaaaaaaaaaaaaaaabbbbbbbbbbbbbbbbbbbbbbbbcccccccccccc.txt"
Notice, I did not list the server name portion as it is my understanding that it does not apply to the url limit. Also the url is not encoded. As I understand, the SP limitations have to do with non-encoded urls. The path above is 257 characters long, which is under the 260 limit. SharePoint will allow me to upload this file. I can rename the file to be longer (i.e. 259 characters), it works without issue. However, if I try to rename it to anything shorter, I receive the below error.
Is this a bug in SharePoint, or perhaps am I reaching a url limit that I am not aware of?
