Confused-in-English-writing-due-to-different-styles-adopted-in-URLs

Regards !

I am confused in English writing due to different styles adopted in URLs specially by:

1. cr4.globalspec.com

<http://cr4.globalspec.com/thread/22447/parallel-capacitance>

Dash used in place of <Space>

2. globalspec.com

<.../Telecommunications_Networking/RF_Microwave_Wireless_Components/RF_Frequency_Multipliers>

Under-score used in place of <Space>

3. wikipedia.org

<http://en.wikipedia.org/wiki/List_of_academic_disciplines>

Under-score used in place of <Space>

Some other websites:

<http://www.webopedia.com/TERM/d/output_device.html>.

http://www.sizes.com/materls/black_blasting_powder.htm

<http://www.thatdamnpc.com/tips-to-keep-your-pc-from-overheating/>

etc etc.

A file saved as: Spray Painting Equipment (Paint Sprayers).txt

cannot be searched by windows & 3rd-party tools like baregrep.exe

but when saved as:

Spray-Painting-Equipment_Paint-Sprayers.txt *** or

Spray-Painting-Equipment-Paint-Sprayers.txt

can be searched by both.

Note:

*** I separate groups with _ <Underscre> in file names to access the file & group like:

Main group in which file is to be: Spray-Painting-Equipment & Paint-Sprayers.txt is the file.

Following is the original text from a website:

Note: I have split the URL in 3 parts for clarity in text file.

Spray Painting Equipment (Paint Sprayers)

<http://process-equipment.globalspec.com/

learnmore/Manufacturing_Process_Equipment/

Surface_Coating_Protection/Painting_Equipment>

I do not know the correct rules for such writing.

Any body please come forward for help !!!!!

Thanks & kind regards.
