## Issue: Problems with Mail Attachments After Upgrading from Apache Hop
2.13 to 2.14
### Description
After upgrading from Apache Hop 2.13 to 2.14, I experienced issues with
sending emails that have attachments in my workflow. Specifically:
- The attachments are not being sent with the email.
- In the "Mail" action, under the "Attached Files" tab, the file type
selection is not saved or displayed in the UI, even though it is specified in
the XML configuration.
### Technical Details
Upon reviewing the XML configuration files between versions 2.13 and 2.14, I
noticed a change in the structure for specifying file types:
**In 2.13:**
```xml
<filetypes>
<filetype>GENERAL</filetype>
</filetypes>
```
**In 2.14:**
```xml
<fileTypes>
<fileType>General</fileType>
</fileTypes>
```
It seems that the change in the XML tags and the case sensitivity of the
values might be causing the issue.
Additionally, I had to manually edit the workflow `.hwf` files using VS Code
to update the tag to the new format. Only after making this change did the
email sending with attachments start working again.
### Steps to Reproduce
1. Upgrade a workflow from Apache Hop 2.13 to 2.14.
2. Configure a "Mail" action with attached files.
3. Save and reopen the workflow.
4. Check the "Attached Files" tab and attempt to send emails with
attachments.
