317661 - Renaming attachment when saving removes file extension

Status: RESOLVED DUPLICATE of bug 298074

(Thunderbird :: Mail Window Front End, defect)

Description

[Adam Piggott]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.0; en-GB; rv:1.7.12) Gecko/20050919 Firefox/1.0.7
Build Identifier: 1.5 (20051111)

With Windows Explorer set to "Hide file extensions for known file types", when you save an attachment after choosing a different file name, Thunderbird strips the file extension from the attachment. This is confusing and troublesome for non-computer savvy users.

This also affects Windows XP.

Reproducible: Always

Steps to Reproduce:
1. Set Windows Explorer to hide file extensions for known file types (Tools->Folder options->View)
2. Create a new email message
3. Attach a file with a "known" file type, e.g. picture.jpg
4. Save the message and move it to Inbox
5. Open the email, right-click attachment and select Save As...
6. Type a different file name and save
Actual Results:  
File is saved with given file name but file extension (which is not shown in the file Save Attachment dialogue) is stripped.

Expected Results:  
File is saved with given file name using original extension. I would expect if a file extension is given with the name it should be used instead. Other programs use the "Save file as type" drop-down menu with the original file type selected by default.

Not sure if this is a dupe of Core bug 129979, definitely related though.
