[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] Dewinter:
hi folks, i finally got a way to copy office / PDF files directly from computer, these files will show up in Office Hub/ Adobe Reader's Document List

before you start, make sure you get TouchXplorer work on your phone.

1. you need to do some registry hacks to make the wp7 device visible in My Computer/ Explorer , here you can see the tutorial http://xdaforums.com/showthread.php?t=915664.

OR: Modify these Registry Entries

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USB\VID_045E&PID_04EC&MI_00\6&210a541a&0&0000\Device Parameters]
"EnableLegacySupport"=dword:00000001
"PortableDeviceNameSpaceExcludeFromShell"=dword:00000000
"ShowInShell"=dword:00000001

Once you're done , CLOSE ZUNE, you should see 2 wp7 devices in your computer, they're exactly the same. just choose one open it and you'll see folders like Album Video Music etc, these are your zune folders.

[TIP], if you open your device/storage and see nothing there, you have to delete one registry key and reconnect your phone.

the registry key is :

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USB\VID_045E&PID_04EC&MI_00\6&210a541a&0&0000\

Device Parameters\DeviceSelectiveSuspended]

delete that key , and you'll see those Zune folders.

2. now we can copy files to the Phone and make them show up in Office Hub or Acrobat Reader.

first, pick one of the Zune Folders, never create one 'cause you'll never see it from the Phone. just use the existing folders , i recommend "Video" folder.

copy a file to the Video folder, eg. officetest.docx,

open your touchXplorer, goto "My Documents"\"Zune"\"Content"

you'll see folders like 0100 0200 0300 0400 0600, these are the music / pictures / video folders of zune, and all files inside are named using numbers.

now open "0400"(in my case, might be different on other phones, you have to find it yourself) and you'll see a folder named "02", open this "02" folder, what do you see?? yes,a "20.z"(the number varies) file, this is exactly the officetest.docx you just copied to phone.

rename the "20.z" files back to "officetest.docx" using TouchXplorer , double click the file ,it will open in office .

you can cut it, and paste to \My Documents of your phone, open Office Hub, you just have the "officetest.docx" there

even you renamed the "20.z" file and moved it to \My Document. you can still see the "officetest.docx" in the "Video" folder on your computer, you should delete the "officetest.docx" to save some space, it's safe, actually, when you rename the "20.z" file to "officetest.docx", the phone did a copy job , not just rename.

EASY Enough ???

3. well, you can do the same with .PDF files if you installed the Adobe Reader.

once you renamed this "xx.z" (xx is a number) back to eg. "mypdffile.pdf" using TouchXplorer, you may try to double tap the pdf file and open it. but to PDF files , it's NOT working, the adobe reader will say "invalid path"

I know exactly what's going on, office files are opened by office apps like word etc. they're WP7 Stock programs from M$ and got very high privileges, they can access any folders. but to poor Adobe Reader, it can only access its isolated storage.

so what we need to do is: find adobe reader's isolated storage folder and move the "mypdffile.pdf" there, you can then double tap the file and open it. and when you open Adobe Reader , you'll see the "mypdffile.pdf" right under the "Documents" list.

the Adobe Reader's IsolatedStorage folder is at

\Applications\Data\BC4F319A-9A9A-DF11A490-00237DE2..\Data\IsolatedStore

just put the pdf files here

1. I'm chinese and my english sucks, sorry if you can't understand

2. the office program on WP7 and Adobe Reader 9.0 for WP7 really sucks
