There was an error opening the document. The file size exceeds the limit allowed and cannot be saved PDF Error
When opening a pdf file from SharePoint, you get an error message and the file will not open. "There was an error opening the document. The file size exceeds the limit allowed and cannot be saved".
Issue: This is caused by a download limit in the registry settings. It is not related to the file size upload limit set in SharePoint central admin.
Solution: Make a change in the registry settings.
· Go to Run and type regedit.
· Find this path: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WebClient\Parameters
· Right-click on the FileSizeLimitInBytes and click Modify
· Click on Decimal
· In the Value data box, type 4294967295, and then click OK. Note this sets the maximum you can download from the WebDAV to 4 GB at one time.
Note: Restart your computer if necessary or re-start WEBCLIENT service
