Sequenced URLs
--------------

LetMeAtIt can now download sequenced URLs, e.g. those that have a large fixed portion but with an incrementing number somewhere within.
For example:
http://www.microsoft.com/file/part01.bin
http://www.microsoft.com/file/part02.bin
http://www.microsoft.com/file/part03.bin
...
http://www.microsoft.com/file/part45.bin
etc

How To Download
----------------
To download them, the URL field needs to be of a special format consisting of:
The base URL
The starting point
The ending point (inclusive)
How many numbers there are
An optional padding character (defaults to 0)

Enter the base URL as you would normally, but replace the incrementing number with '{}'. That's an open curly bracket and a close curly bracket next to each other.

Then a space to separate the URL from the parameters.

Then the parameters given in the order above, separated by commas. 

Using the example URLs above, to download all 45 parts you'd enter the following in the URL field:
http://www.microsoft.com/file/part{}.bin 1,45,2,0

This is equivalent to the following as the padding character is optional

http://www.microsoft.com/file/part{}.bin 1,45,2

You will receieve an error if there are any spaces in the parameter portion, so if you're having trouble check for those.


Considerations
---------------
If the fixed URL portion contains a space, it ordinarily doesn't matter. As long as there is a space between the url and the parameters, LetMeAtIt should detect it correctly. If you encounter any issues, please try replacing spaces in the fixed URL portion with '%20'.

So the sequence
http://www.microsoft.com/my file/part000.bin
http://www.microsoft.com/my file/part001.bin
http://www.microsoft.com/my file/part002.bin
...
http://www.microsoft.com/my file/part038.bin

Could be entered either as:
http://www.microsoft.com/my file/part{}.bin 0,38,3

or

http://www.microsoft.com/my file/part{}.bin 0,38,3


Joining
---------

If you download a parts of a video using the sequenced method, they will not be joined automatically like some plugins do when downloading multi part videos.

This is because plugins use specific knowledge of their sites' video formats to be able to join correctly. A generic method such as this sequenced downloading doesn't have that knowledge and would probably end up generating corrupt files.

Likewise, if the sequence represents a multi-part binary file such as an archive, it also will not be joined into a whole for the same reasons.
