Get-SmbOpenFile retrieves a list of opened files on a given SMB share. This command is useful for identifying and managing file access, such as determining which users have opened specific files or which files are currently being accessed.

Options/Flags

  • -Size: Specifies the count of open files to retrieve.
  • -Server: Specifies the name of the SMB server hosting the share.
