As VolvoGirl has stated the tilde itself DOES NOT designate
a .pdf file.
Perhaps a little explanation
regarding the file naming structure used by Windows (& MAC) systems.
Each file and program have unique
names and are presented as "filename.exten
" Where:
filename
is a unique name assigned to a file; and can typically be just about anything
exten
is a specific extension that are used by various programs to
attached 'ownership' to that type file
Specifically in this case .tax15 identifies a
file as being a data file created by TTax for the tax year 2015. A file
extension of .pdf identifies files intended to be readable by a
PDF (Portable Document File) viewer program (eg Adobe
Reader). That is basically the only way .pdf files are
identified --a prefix of ~ (tilde) has no special meaning with
regard to .pdf file.
When a filename if prefixed with a tilde the sorting
sequence of a list of files will be altered. Depending on sorting
preferences at any given time (based on user selection) the files prefixed with
a tilde will be listed before a similarly named file without the tilde
(or, based on user selection, the tilde prefixed files could be listed
after similarly named files without the tilde).
It may be that a setting on your
PC prevents the system from displaying the filename extensions. To change
your PC's setting to show full filenames (with extensions) you need to navigate
to "Folder Options" by clicking the start menu and entering
"folder options" in the search box.
1. Then click on "Folder Options" in the list
displayed.
2. Click on the "View" tab; and
3. scroll down the list to: "Hidden files and
folders".
4. Then click/select the option to "Show hidden files,
folders, and drives".
5. Finally click 'Apply" and then click "OK".
