File size limitations

Maximim size limit for an individual file 25 MB (25,000 KB)

The file size of the document can be determined by locating it on the computer, using the right-click option with a mouse (Shift + F10 on Windows OS, or Ctrl + 5 on Mac OS), followed by selecting "Properties".

Please note that time-out issues may be experienced with files above the maximum allowed size, depending on the internet connection.

File names can include most characters, including letters, numbers, spaces, punctuation marks, and/or symbols, except for the following:

< left angle bracket or less-than sign > right angle bracket or more-than sign
