A Chinese court has ordered the software giant to stop producing and selling versions of its Windows OS that include Chinese fonts developed by a local software company. Microsoft’s (MSFT) use of two Chinese fonts developed by Zhongyi Electronic, a Beijing-based software company, was not covered by the licensing agreement between the two, the court found, and therefore infringed on Zhongyi’s rights. And so Microsoft must pull from the shelves Chinese language editions of Windows 98, Windows 2000, Windows XP and Windows Server 2003.

“By winning this case against an internationally well-known company like Microsoft, it shows that China, although still a developing country, is taking positive steps to protect intellectual property rights,” an attorney for Zhongyi Electronic told Reuters.

Microsoft, for its part, insists its agreement with Zhongyi covered its use of the fonts at issue and plans to appeal the decision. “Microsoft respects intellectual property rights,” the company said in a statement. “We use third party IPs only when we have a legitimate right to do so.”

And if Microsoft should fail in its appeal? Well, piracy is so rampant in China, a court order preventing the company from selling certain versions of Windows isn’t exactly going to hamstring Microsoft’s business. “The majority of operating systems in the market today are illegal copies, and the ones that are Zhongyi-related have an even smaller share of the market,” Analysys International analyst Edward Yu explains. “So I don’t think it will have much impact on Microsoft’s business.”

Here are a few questions I’ve received recently from people like you, and my answers. I have edited and restated the questions a bit, for readability. This week my mailbox contained questions about moving a 25 gigabyte file from a Mac to a PC, switching the iPhone to horizontal mode, and enlarging font size.

How can I move a 25 gigabyte file from a Mac to a PC?

If the two computers are on the same network, you could simply transfer the file over the network. Or, you could establish an ad hoc network using what’s called a “crossover” network cable, though that might require some technical expertise. You might also try uploading the file from the Mac to one of the online backup-and-storage services and then downloading it to the PC. For instance, a service called MediaMax, at mediamax.com, offers 25 gigabytes of storage free, and claims to work with both Macs and PCs.

For the best combination of simplicity and speed, I suggest you purchase an external USB hard drive, formatted for Windows. The Mac should be able to instantly recognize it, since Macs can read Windows disks and can write to them as well, as long as they use a standard Windows format called FAT. You would just plug the drive into the Mac, copy the file to it, then remove it from the Mac, plug it into the PC and copy the file from the external drive to the PC’s internal hard disk. Update: Due to technical limitations, you can’t copy a file larger than four gigabytes in size to a disk drive formatted using the FAT file system.

A 30-gigabyte or larger Apple iPod can also be used as an external hard disk and thus would do the trick — provided it is formatted for Windows, is set to work in disk mode, and has enough room to hold the file.

Is it possible to switch the iPhone into horizontal mode when typing emails, which would allow for wider spacing on the onscreen keyboard when typing, thus helping to eliminate typing errors?

No. While the iPhone’s Web browser, built-in iPod and photo program can operate in landscape, or horizontal, mode, its email program works only in vertical, or portrait, mode. However, in my daily experience with the iPhone, I have actually found the horizontal version of the keyboard (which appears in the browser) clumsier to use than the narrower vertical version.

My grandmother, age 85, recently stopped our weekly emails and when I asked why, she said the 14″ screen has become difficult to use. I considered a 20″ LCD, but the bigger screens seem to shrink the font, and the Magnifier option under Accessibility isn’t agreeable to her. What other options are there?

I assume from your question that she is running Windows XP. If so, you can enlarge the fonts she uses in several ways, to offset the shrinkage you noted on the higher-resolution monitor. First, in Windows itself, go to the Display control panel, click on the Appearance tab, and in the Font Size menu, select “Extra Large Fonts.”

Most email programs and Web browsers also offer options to enlarge the size of text. For instance, in Outlook Express, go to Tools, then Options, then click on the Read tab and the Fonts button. Change the Font Size setting to “largest.” In the Compose tab, click the “Font Settings” button and select a large font size. While reading an email, she can increase the font size by clicking on the View menu, selecting “Text Size,” and then selecting “Largest.” There is a similar “Text Size” setting in Internet Explorer, under either the View or Page menu, depending on which version she is using.

Finally, if she is reading her email inside Internet Explorer, you might try a very good $25 utility called WebEyes, which enlarges the type on any Web page. I tested it in 2004 and liked it (Read the review). You can get it at www.ionwebeyes.com.

Corrections & Amplifications:

Due to technical limitations, an individual can’t copy a file larger than four gigabytes in size to a disk drive formatted using the Windows file system called FAT. A previous version of this column incorrectly advised that a 25-gigabyte file could be copied to such a disk drive.
