My filetype.pm control file has two PDF related entries in the following order:

Adobe-PDF,0,X,0,.PDF
Adobe-PDF,S,0,\037PDF\045

Thank you. I've added these two to my filetype.pm 

[quote user="Euler GERMAN"]

Strangely, my mime-map.pm file has only a single line "Text/HTML = HTML-text" (no quotes). I'm assuming it has little or no-effect on how Pmail handles attachments. BTW, this is the same file I have under my \Programs\RESOURCE directory.

Anyway, I remember of recipients complaining about attachments sent by me were found corrupt after being processed by Pmail. This happened a long time ago and I don't remember which measures taken corrected the problem. My guess is that telling Pmail to behave by the "Attachment type" instead of file extension is a good guess. As an example, I remember plain-text attachments being added to the message body instead of attached as a file. I used a trick (can't remember who whispered it to me) to make Pmail treat plain-text as binary by adding the line below to filetype.pm:

[code];Text,0,X,0,.TXT
binary,0,R,0,\\032,R,0,\\013\\010,R,0,e,R,0,E,R,0,t,R,0,T,R,0,n,R,0,N,R,0,r,R,0,R,R,0,i,R,0,I,R,0,o,R,0,O,R,0,a,R,0,A,R,0,s,R,0,S,R,0,d,R,0,D,R,0,h,R,0,H,R,0,l,R,0,L,R,0,c,R,0,C,R,0,f,R,0,F,R,0,p,R,0,P,R,0,u,R,0,U,R,0,m,R,0,M
[/code]

Notice that the original "Text" is commented.

Lastly, anyone can get a copy of my current filtype.pm control file HERE for the next 7 days. I'm not saying it is perfect, but it plays well here without hiccups AFAIK.

I've added this too.

I'll start sending PDFs again by right clicking the file to send to Pegasus and see if I get any more complaints of not being able to read PDF attachments.

So far it looks good. Pegasus is now saying that my attachment is a PDF, unlike before. However it still wants to use encoding. I'll let Pegasus do that for now.

 Finally made the move up from XP to windows 7 on my journey to 10. Recently have had problems downloading attachments pdf & docx etc.

When I receive the information from people, and hit attachment to go to download it...it keeps showing type unknown re ere any special settings to cofrrect this problem?

finally 

Here are my notes on the subject attachment file types (both outbound and inbound):

Quoted from the Pegasus Mail manual:

FILETYPE.PM -  Pegasus Mail uses this file to work out what attachment type it should associate with a given file. It is used when "Mailer decides" is chosen as the attachment type in the Attachments view of the Message editor. Having a well-stocked FILETYPE.PM file means that your messages are more likely to be sent with the information necessary to allow other programs to associate file viewers with them.  Instructions are contained within the file which is a plain text file.

MIME-MAP.PM - Pegasus Mail uses this file to translate custom MIME content types into attachment types. New MIME content types are being added all the time, and using this file allows Pegasus Mail both to generate them in outgoing mail and to recognize them in incoming mail. For example, say someone sends you a MIME message with the content type "Application/MyWordProcessor", and you have an entry that says that "Appli-
cation/MyWordProcessor" is the same as "MS-Word", then Pegasus Mail will be able to work out that it can run MS-Word to view the document.

Example by BF:

Adding the following lines to FILETYPE.PM will identify the file type of .docx files as "MS-DOCX" and .xslm files as "MS-XLSX".

MS-DOCX,0,X,0,.DOCX
MS-XLSX,0,X,0,.XLSX

Taking this a step further, adding the following lines to MIME-MAP.PM will identify the file type in the Pegasus Mail reader Attachments tab as "Microsoft Office Word Document" and" Microsoft Office Excel Spreadsheet".

application/vnd.openxmlformats-officedocument.wordprocessingml.document = MS-DOCX
application/vnd.openxmlformats-officedocument.spreadsheetml.sheet = MS-XLSX

NOTE:   "MS-DOCX" and "MS-XLSX" _MUST_  be the same text as the corresponding <file type>  entry that you have in FILETYPE.PM

 My MIME-MAP.PM file contains these entries:

Text/HTML = HTML-text
application/pdf = PDF-document
application/vnd.openxmlformats-officedocument.wordprocessingml.document = MS-DOCX
application/vnd.openxmlformats-officedocument.spreadsheetml.sheet = MS-XLSX
application/ics = iCalendar-Event-File
application/vcs = vCalendar-Event-File
application/dwg = AutoCAD

My FILETYPE.PM file contains these entries:

MS-Word,1,S,0,\219\165\045
PCEXE,1,X,0,.EXE,S,0,MZ
PCEXE,1,X,0,.DLL,S,0,MZ

Appreciate your time and effort from your notes but with all do respect this old guy is somewhat lost.

As mentioned the downloaded information (attachments) do identify the attachment as a docx and/or a pdf but unable to download

either and I've never had this happen to me before in all the years I've used Pegasus

I used a something called PC mover to move all my files from the old (XP) to the new computer with Window 7 and I just don't know what happened

I guess what I was looking for  was possibly a fix...via office or maybe reload Pegasus or basically find out what I currently have and maybe correct.

Thanks for bearing with me

I forgot to mention I checked under incoming mail and content viewer but not sure if I was supposed to add something

and if so, it is asking me question and I didn't want to mess with anything

[quote user="Eshtaol"]As mentioned the downloaded information (attachments) do identify the attachment as a docx and/or a pdf[/quote]

OK, the first question would be whether you installed the applications to open these file types on your system (and I mean literally install, not copy) and set them as default appplications for opening PDFs or DOCs in Windows?

[quote user="Eshtaol"]I used a something called PC mover to move all my files from the old (XP) to the new computer with Window 7 and I just don't know what happened[/quote]

Assuming you did this with all the files you think to be part of the Pegasus Mail setup it's pretty likely they have been copied to an invalid path especially since XP allowed paths to be used without issues that are not supposed to be used by applications like Pegasus Mail anymore because of security considerations. IOW: My first suggestion would be to do a fresh install to a new path without touching the existing one as offered by Pegasus Mail's installer. The only thing you must not do is selecting a new install path below any kind of ...\program files\... directory. If this works properly you could download some emails with the attachments in questions and try to open them there. If this works you will need to copy over your existing folders and adresses etc. to your new setup which might become a little time consuming I'm afraid - but it's definitely possible!

This discussion is flagged as answered but a PM received from Eshtaol indicates that is isn't so here goes...

In the original post the question was asked:

[quote user="Eshtaol"]When I receive the information from people,

and hit attachment to go to download it...it keeps showing type unknown

re ere any special settings to cofrrect this problem?[/quote]

I provided information about mime-map.pm and filetype.pm which control the file types of incoming and outgoing attachments.  I was assuming that the question was about how to fix the problem of attachments being listed in the attachment tab with a file type as "type unknown".  I'm now wondering if the problem is that the attachments won't open on double click or when hitting the "Open" button.

If this is the case try these troubleshooting suggestions/solutions:

• Attachment preview can cause a double click not to work.  Try turning off attachment preview.  You must get out of and then return to the attachment pane for the new setting to take effect.
  
• If the attached file appears to try to open, save the file to your hard drive and then navigate to it with a file explorer and double click it. 
  
• If it doesn't open, the app it needs either isn't installed, isn't installed correctly, or isn't set as the system default app for that file type.  If you can open this file with an application but not by double clicking from a file explorer, go back to Pegasus Mail and add that app as a Helper

  Application in Tools > Options > Incoming mail > Content
  viewers.  Enable the "file extension" option and the "Run this program" option, browsing to select the executable file of the appropriate application.

• If it opens, then go back to Pegasus Mail and try adding that app as a Helper Application in Tools > Options > Incoming mail > Content
  viewers.  Enable the "file extension" option and the "Let windows choose and run an appropriate application" option.  This SHOULD work if that application is the system default application for that extension but in some cases it doesn't.  In that case, try the "Run this program" option as mentioned above.
  

I have been having a problem lately of some recipients not being able to open PDF's that I have been emailing to them.

I then noticed that Pegasus came up with Filetype unknown and Encoding mailer decides when right clicking on a PDF and "sending" it to Pegasus.

I then started attaching PDF's to emails by adding the attachment within the email, forcing Pegasus to load it as an Acrobat file and no encoding. My recipients are then able to open the PDF. 

I have added the 4 lines that Brian has added to his filetype.pm and to the mime-map.pm hope this will fix the identification problem and allow all of my recipients to be able to open the PDFs that I am sending to them.
