Why does the folder name change its color to blue? [duplicate]

Solution 1:

It's possible that you're dealing with compressed files, and the two Windows computers just have different configurations for how to display them.

Windows XP, as well as Windows 7, will by default display compressed files in blue and encrypted files in green, while files which are both uncompressed and unencrypted are displayed in black. This is easily configurable in Folder Options, which is accessible in Windows 7 as follows:

Control Panel
  -> Appearance and Personalization
    -> Folder Options
      -> View
        -> Show Encrypted or Compressed NTFS Files in Color

Solution 2:

By default, Windows Explorer represents compressed files and folders as blue. It may be that your configuration between Windows XP and 7 is different. This particular setting is found under Folder Options > View > Advanced settings > Show encrypted or compressed NTFS files in color.
