Attachments


Emails can have files added to them. A file enclosed in an email message is known as an attachment. There are a number of different sources a file can be attached to an email from. They include the following.


Attachment Sources


Files from the computer's Hard Disk Drive:

Files stored on a computer's hard drive can be attached to email messages. The given file to be attached must be uploaded to the email in order to attach it to an email.




Files from a USB drive:

Files from a USB drive can be attached to an email, too. The only difference is the source of the file. Instead of the file coming from the hard drive, it is attached from a USB drive. USB drives are connected to the computer through a USB port.




Files from an email account’s own storage drive:

Files from an email account’s own storage drive for files if one is present can attached to email messages as inline file attachments. An inline file attachment is a file attachment from an email account itself.





Files from a network drive:

Files from a network drive is an option to consider when network drives can be accessed from a given computer. One example of a network drive is a server’s disk drive. Standalone drives can also be added to computer networks, too.







Ordering of File Attachments



Order of attachments in an email:

Attachments in emails are either ordered from last attached file to first attached file or vice versa.

To change the order of attached files, the attachments must be removed from the email and attached in the order that will result in the new desired order of attached files to the given email message. An example is the following.

File#3 File#2 File#1


Here, the files are ordered from last attached to first attached. The most recent attachment gets listed first, the, the next most recent attachment, and so on. Attachments can be listed vertically or even horizontally in emails, depending on the email service provider or email client.



Attachment Size Restrictions or Limits

Email providers all have attachment size limits. This is mainly for security reasons. Without attachment email attachment size limits, the risk of extremely large file attachments posing a risk to the functionality of email servers would be high. When large files are sent as spam, if the size of the file is too large for the email server to handle, the email server could cease to function. Email attachment size limits are determined and set by the email service provider providing email service. To send files greater than the set maximum size limit, there are means of doing so.
