To send a file which has big size does take time and some solutions to it are as follows:
1) first of all she should spend a little extra money for a better internet connection,
2) secondly she can compress the file by putting it in a .zip or .rar folder,
3) she can copy the text from the .pdf file and then paste on microsoft word and then send to whomever she wants to,
4) and lastly she can minimize the quality of the file so that its size gets reduced.
