To compare your controlled work area files with the database files, use the Reconcile Work Area dialog box.
If you want to change a work area from link-based to copy-based, or vice versa, use the ccm work_area /cb option or select the Use Copies or Use Links option in the Work Area Properties dialog box to convert the work area automatically. See the Reconcile Work Area dialog box for information about converting link-based or copy-based work areas.
You can delete a work area (for example, to remove unwanted uncontrolled files). However, always sync before you delete a work area to ensure that the database is updated with your work area changes. See the Reconcile Work Area dialog box.
If you removed files from your work area and you want to write the database versions back into the work area, use the Synchronize operation to re-create the work area.
