Why is the HTM file of a page saved in FF also being deleted, if one deletes the subfolder with the corresponding files?

Question

Alright, let me explain: When I'm saving a web page in FF, this will create a .HTM file as well as a subdirectory with matching filename plus suffix "-Dateien" (German version - I'd guess in the English version it would probably be "-files" or maybe "-data" instead...). Anyway, now if I delete that subdirectory (including all its content) with the Windows Explorer (I'm still using XP, btw), it'll also delete the corresponding .HTM file in the parent directory. Question is: Why/how does it do that? Could that be some hard or symbolic link phenomenon that escapes me?
Greetings from Munich & thanks in advance!

That is a Windows feature called connected files that connects the main file and the folder with the other files for certain file operations and HTML files among others.<br />
If you delete one of them then the other is deleted automatically (the same for Copy).

You can use the registry editor (regedit.exe) to create a NoFileFolderConnection key of type REG DWORD and set the value to 0x01 to disable this "Manipulate connected files as a unit" feature.
*HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\NoFileFolderConnection: REG_DWORD 0x01
Change the value to 0x00 to re enable.
