I have a drive mapped to sharepoint share. I also can access the Document library from internet explorer in Sharepoint . I used to be able to add files
But if I try to open a pdf file that is on my computer windows 7 then try to save As and select the sharepoint share, it will come up with the error shown in the screenshot. (The document could not be saved. A file write error has occurred."
If I drag PDF from my computer to the sharepoint share, I receive the error "file name you specified is not valid or too long"
I included a screenshot about that too
if I go to sharepoint document library from internet browser and try to add the pdf file, it will give me error shown in screenshot.
these errors just started to popup
Any help will be very much appreciated.
