Case: Some of the PDF is not viewable in UI

Cause: Some of the PDF which has name in the sequence "E -Application_Verso_v1.1_1570480117439.pdf" like 2 dots are appearing in complete file name is causing the issue. 

The file extension is parsed by using dot as a delimiter and getting the second element of  file name array.

Correction: We are now fetching the last element of the array now each time where we will get the file extension correctly each time, regardless of the dots present in the file name.
