HOW TO: Clean Profiles By Using the Cprofile Command in Terminal Services

This article was previously published under Q320186
This step-by-step article describes how to clean profiles by using the Cprofile command in Terminal Services. The Cprofile command removes wasted space from profiles, and removes user-specific file associations from the registry if user-specific file associations are turned off.

Users can use file associations to associate a specific program with a specific file type. A server uses file associations to determine what program to use to access files of a particular type. File types are registered by using Explorer. With per-user file associations, each user can have a different program associated with a specific file type. For example, one user might have .doc files associated with Microsoft Word, and another user might have .doc files associated with WordPad.

Note that user-specific file associations in Microsoft Windows NT 4.0, Terminal Server Edition are turned on or off by using the Peruser command. If the user-specific file associations are turned on, Cprofile removes only the wasted space from the user's profile. If user-specific file associations are turned off, Cprofile also removes the corresponding registry entries.

When items are removed from a user's profile, the corresponding registry does not become smaller. Cprofile is useful in clearing this wasted space from the registry.

NOTE: Profiles that are currently in use are not modified, and you must be an administrator to run Cprofile.

back to the top


  • /?
    Displays the syntax for the command and information about the command's options.
  • /l
    Cleans all local profiles. You can also specify a list of additional profiles in the filelist parameter.
  • /i
    Interactively prompts the user with each profile.
  • /v
    Displays information about the actions that are being performed.
  • filelist
    A list of files from which you want to remove user-specific file associations. Separate each file in the list with a space. File names can contain wildcard characters.

    NOTE: Use quotation marks to enclose paths that contain spaces. For example, type cprofile "c:\documents and settings\tester\ntuser.dat" "c:\documents and settings\tester2\ntuser.dat".

An Example of Using the Cprofile Command

To clean all local profiles and clean an additional profile by using a network path, type cprofile /l /i /v "\\server\C$\Documents and Settings\tester2\ntuser.dat" at a command prompt, and then press ENTER. The command interactively prompts you with each profile, and displays information about the actions that are being performed, similar to the following prompts:
Processing file:  C:\Documents and Settings\Tester\NTUSER.DATModify (Y)es, (N)o, or (Q)uit [default=n]? yProcessing file:  C:\Documents and Settings\Administrator\NTUSER.DATModify (Y)es, (N)o, or (Q)uit [default=n]? nProcessing file:  \\zippy\C$\Documents and Settings\Tester2\ntuser.datModify (Y)es, (N)o, or (Q)uit [default=n]? y

Note that profiles that are currently in use are not modified. To work around this issue, schedule the Cprofile command to run when the server is not busy.
