Permissions

The rows of checkboxes are used to set/unset specific permissions for the Owner (the owner of the file); the Group (members of file group); and Others (all others). The label R stands for “read permissions”, W for “write” and X for “execute”. For directories the “execute permission” means permission to enter the directory (make it working directory).

When explicitly changing permissions of existing remote files, the checkboxes can be set to undefined state (grayed checkbox on Windows 2000 and older, green square on default theme of Windows XP). It means that the particular permissions should be left to its current state. This is useful when you want to change one particular permission for set of files/directories that have different permissions.

Note that this will not work fully for SCP protocol for files in subdirectories.

The Octal box shows octal number representation of the permissions set by the above checkboxes. You can enter the octal format directly instead of manually ticking the checkboxes. If you enter only three numbers, the leading zero for unset special permissions is added automatically. When any of the checkboxes are in undefined state the Octal box is empty.

Note that if permissions box pops up from an edit box, you can enter permissions in octal format directly into the edit box, without having to pop it up.

The Add X to directories checkbox makes WinSCP add “execute” permission to directories for every permission group (owner/group/others) where there is a “read” permission set already.

On Properties dialog the option is available only when there is at least one directory selected. Also it will not work for SCP protocol for subdirectories of selected directories.

The checkbox is disabled, if you check “execute” permissions explicitly for all permission groups, as it makes it effectively useless.
