Before moving any files in response to low disk space, verify that no other files on the volume are responsible for the condition of low disk space.

You might need to relocate the database file, the log files, or both, if disk space on the volume on which they are stored becomes low. Before moving the database file or log files, examine the size of the database folder, logs folder, or both, if they are stored in the same location, relative to the size of the volume to verify that these files are the cause of low disk space. Include the size of the SYSVOL folder if it is on the same partition.

Administrative Credentials

If you are online when comparing the size of the directory database files, you must be a member of the Domain Admins group. If you are offline, you must provide the Directory Services Restore Mode password for the local administrator account.

To compare the size of the directory database files to the volume size

  1. In Windows Explorer, click My Computer.

  2. On the View menu, click Details.

  3. In the Name column in the details pane, locate the volume. Make a note of the value in the Total Size column.

  4. Navigate to the folder that stores the database file, the log files, or both.

  5. Right-click the folder, and then click Properties. Make a note of the value in Size on disk.

  6. If the volume includes SYSVOL, navigate to that folder and repeat step 5.

  7. Compare the sizes. If the combined size of the relevant database files and SYSVOL files (if appropriate) is significantly smaller than the volume size, then check the contents of the volume for other files.

  8. If other files are present, move those files and reassess the disk space on the volume.
