To check the size of files

E-mail messages are very small but it is a good idea to check the size of files before you attach them.  Many e-mail systems do not receive files larger than 3 Mb.   Large files take longer to send and therefore cost more to send. 

To check the size of files before you attach them, click on Views which is found when you look for files.  Go to Details. 

The size of the files are shown.  The people to whom you send files will not like unnecessarily large files.
