PlayStation Download Manager / Booster is an application designed to increase the download speeds of the PlayStation Notwork, it can install both free and paid content as long as you've paid for it.
In order to create a speed boost, it creates multiple segments which will draw data from the servers using multi-threading, this allows you to achieve the maximum speed of your line; unlike the PS3 which uses only 1 transfer.
Your PC can also be faster at downloading in general due to several factors, including it's connection method, processor speed, RAM and TCP Optimizations.

Develio13 - Mashing the Source, and removing bugs / limitations of the original code.
Why has it taken so long to fix the bugs?
The development between 3.27 & 3.41 consisted on an advanced study of the C# programming language considering my knowledge was average and I only had a little understanding of how it worked, and this is why it has taken a much longer period of time to release compared to those before, which only took several hours.
The original code was limited and could only handle up to 2 Gigabytes of data, and relied on 32 Bit Integers, this had to be changed and was difficult; practically a 40% recode and many improvements in other areas.
Example of the applications use:
Downloading a PS3 Demo on a 50 Megabit Fibre-Optic line will not achieve more than 700 - 800 Kilobytes /ps, however using multiple segments you'll achieve the full line speed of around 5 - 6 Megabytes /ps.
Recommended Maximum Segments and Minimum Segment Size:
Maximum Segments = (Line Speed / 256)
Minimum Segment Size = (Line Speed / Maximum Segments) * 100,000
Line Speed is measured in Kilobits which is (Kilobyte / 8)
If any numbers contain a decimal point, then round to the nearest whole
number.
For those who find the above to complex, just use the following:
Max Segments = 20
Min Segment Size = 25000000
Line Speed is 5000 Kilobits (625 Kilobytes) for the above information
[These figures are based on my recent testing]
NOTE: Incorrect settings may reduce the speed, below it's maximum potential.
Changes from 3.27 to 3.41:
• Added support for files larger than 2048MB
• Fixed Options Menu
• Several Performance Enhancements
• Prevention of multiple proxy.exe causing an error (prep.bat)
• Outputs url log for debugging purposes, for those encountering
and error upon file downloads.
Options Menu:
• Schedule Downloads
• Adjust Proxy Settings for downloads (not PS3)
• Change Minimum Segment Size
• Set Maximum of Segments
And many more.
Quick Start Guide:
1. Make sure .NET framework 3.5 or greater is installed.
2. Start PSNDM[Version Number].exe, and extract to current path.
3. Start Internal IP.bat
4. Write down your IP Address
5. Start your Playstation Console
6. Goto Network Settings and select Internet Connection Settings
7. Proceed with Custom Settings until Proxy Server
8. Choose Use and enter your IP Address, and port = 27
9. Save your changes by completing the wizard
10. Start the PSN DM.exe (NOT Proxy.exe)

FAQ:
Q: When I download files, I get an error about illegal characters in path?
A: E-Mail the Url-Log.txt and time / date of download and a copy of your Country.txt and Char_Illegal.txt, I should be able to identify the issue within 24 hours, if not minutes.
Q: Application won't run because required files are missing?
A: Download the application again, and delete the older version.
Q: When downloading from PSN it says "Please Wait" until error occurs?
A: Once it says "Please Wait" just press Circle and wait until download manager has finished, then download the file from the PSN Again this will take the file from the PC Cache folder instead.
Q: Can I use this for game sharing?
A: Yes, make a copy of the file in the download folder and give this to
your friend / user, then log-in on his / her PS3 with your account and
download the file from the PSN, this will transfer straight from the PC.
Q: Can I install paid content without purchasing it?
A: No, I am unable to implement this and will not being doing so
because I expect Sony would put a stop to this program if it could.
[Only Game Sharing is allowed]
Q: Can this bypass game patches, Playstation Updates?
A: No, this isn't designed for that purpose and will never include bypasses.
Q: Will this install / download to firmwares lower than the latest version?
A: No, it will only work on the latest firmware.
