OIC, OK noted will try out. So I name the 1st file then for output the file name when they are all joined I suppose?
Basically, if the poster of the download links were a sane person.. The files would be named like this:
-EXAMPLE ONLY-
XV-531 Rio.avi.001 or XV-531 Rio.avi.__a
XV-531 Rio.avi.002 or XV-531 Rio.avi.__b
XV-531 Rio.avi.003 or XV-531 Rio.avi.__c
XV-531 Rio.avi.004 or XV-531 Rio.avi.__d
You download ALL THE FILES FIRST then JOIN THEM AT THE SAME TIME. No need to rename the files. Once they are joined you'll get a single file:
XV-531 Rio.avi
The size of which is equal to the 4 files listed above COMBINED.
From what I can see from your posts, you're unable to see the *.001 on your first file. The said extension (*.001) cannot be seen once you install a file splitter/joiner program because the said program associates with *.001. All files with recognized file extensions (such as *.mp3 and *.avi) cannot be seen by default. The *.001 or *.__a files are also unique because they have an icon. This is also the case with your *.001 files. You can only see *.002 (and so on) files because only the *.001 are recognized by the file splitter/joiner program. This will be the end result (in your case):
XV-531 Rio.avi or XV-531 Rio. (WITH ICON)
XV-531 Rio.avi.002 or XV-531 Rio.avi.__b
XV-531 Rio.avi.003 or XV-531 Rio.avi.__c
XV-531 Rio.avi.004 or XV-531 Rio.avi.__d
Note that the file extension is still there but system hides it from view.
If you want to see the *.001 or *.__a on the first file. Go to TOOLS menu (besides HELP) and click FOLDER OPTIONS. Once a new window opens, click on the VIEW tab and look for the ADVANCE SETTINGS BOX. There you will need to look for an a check box with a text HIDE EXTENSIONS FOR KNOWN FILE TYPES. I assume this check box is enabled so you have to uncheck it. After this you should be able to see the *.001 or *.__a file extension on the first part of every split file.
Note that you will also see file extensions for all the file types (jpg, avi, bmp, mp3, exe, doc, ETC).
The second problem would be the fact that you attempt to JOIN THE FILES WITHOUT COMPLETING THE DOWNLOAD FOR ALL FILES. We're not building Lego parts here. You
DO NOT join part 001 to part 002 first, then add part 003 to the conjoined part 001 & 002, and add part 004 later to the conjoined part 001 002 & 003 and so on. YOU JOIN THE FILES TOGETHER ONCE YOU HAVE THEM ALL ON YOUR DRIVE. For example, you want to download a movie which has four parts. You download all FOUR parts unto your hard-drive first before you attempt to join them.
If my explanation wasn't enough then I guess you'll have to wait for someone else to bump this thread.
I don't wanna be blunt but this discussion is getting ridiculously long. This is definitely not rocket science. This is the basics of basics in Windows.
