(Resolved) SharePoint mapped drive is unable to rename files and folders

I recently faced a problem while mapping a drive to my SharePoint "My Document" folder.  First time It was great that I could be able to open, save, and delete files and folders.  Now I had a problem while renaming files and folders.  No matter how long of short of a name same error popup

"The file name you specified is not valid or too long.  Specify a different file name."

I've mapped the "L" drive to http://MySharePoint.com/My Documents/
Also, "My Computer" it shows the mapped SharePoint drive as a "FAT" filesystem.
Solution#1 Try to remapped the drive without the / Like: http://MySharePoint.com/My Documents
Solution#2 Try to re-map my drive as " https://MySharePoint.com" May be previously you had not drive mapped beginning with "http" as opposed to "https".**
Solution#3**
May be last portion your drive would be like "My%20Documents", So try to remove “My%20Documents" and then Maybe you will be able to rename files.
May be 2 of the given solution make your error wipe out that is Solution 1 and Solution 3 max of time.
