I post this here in case it is of any use to others.
Unless you are super efficient in your filing, there will come a time on larger or long term projects when you know you have a drawing file for something but are not sure where you filed it. Someone might refer to a drawing you sent them in an email weeks, months, or years ago and then you have to scrabble around trying to locate it. On small projects with few drawing files, that is not much of a problem. But on a job that has hundreds of drawings, it can be.
What I have started doing when I send a drawing file out by email is to copy the file path and then add it as a note to the email sent. Providing the file does not get moved in the interim, that should make it easy to find in future. On a Mac, you can get the filepath onto your clipboard by holding down the Option key, right clicking on the file in Finder, and then choosing “Copy [file] as pathname”. Then just paste into the note.
If you don’t have the facility to append notes to your emails, you could just add it to the body of the email after the attachment (say).
