What is a QDS file?
Saved search file created in Microsoft Windows' "My Network Places;" contains the search criteria and scope information for searching folders and files in Active Directory, a centralized permissions management program.
QDS files are used for reopening searches, as well as sharing Active Directory searches with other users.
NOTE: Windows 7 uses .SEARCH-MS files to save local Windows Explorer searches.
