0 Here’s how to force Explorer to display correct filename capitalization:

By default, Explorer displays uppercase (all caps) 8.3 DOS-style filenames (such as "README.TXT") in a "prettier" format (such as "Readme.txt). If the filename has more than eight letters (not including the extension), or if the filename contains at least one space, the capitalization is not modified. (Note: Windows doesn't actually change the capitalization of any files, only the way they're displayed in Explorer.) Here's how to turn off this feature:

Windows 95, Me, 2000, and XP:

• Run the Registry Editor (REGEDIT.EXE).
• Navigate to HKEY_CURRENT_USER\ Software\ Microsoft\ Windows\ CurrentVersion\ Policies\ Explorer.
• If it doesn't already exist, create a new DWORD value named DontPrettyPath. (Edit -> New -> DWORD Value).
• Double-click on the DontPrettyPath value, and type 1 for the value.
• Close the Registry Editor when you're done. You might have to log out and log back in for this change to take effect.

To turn the feature back on, change the value data back to 0, or just delete the value entirely.
