| - | The array of checkboxes is used to set/unset specific permissions. The //Owner// row defines permissions for owner of the file. The //Group// row defines permissions for members of file group. The //Others// row defines permissions for 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). | + | 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 for file (or folder)", //W// for "write" and //X// for "execute". For directories the "execute permission" means permission to enter the directory (make it working directory). |
| - | ===== Special Permissions ===== | + | ===== [[special]] Special Permissions ===== |
| - | There are three special permissions. //Set UID// and //Set GUID// are used with executable files. They grant the user, who execute the file, permissions of file owner or group, respectively. //Sticky bit// for executable files makes the kernel keep the memory image of the process after it has terminated, in order to avoid the overhead of reloading it when it is re-invoked. //Sticky bit// for directories ensures that only the owner of a file can remove or delete the file or directory. | + | There are three special permissions. //Set UID// and //Set GID// are used with executable files.

| Note that while non-Unix systems are usually able to map the 9 simple Unix-style permissions to their own style, they probably won't be able to handle the 3 special permissions. | Note that while non-Unix systems are usually able to map the 9 simple Unix-style permissions to their own style, they probably won't be able to handle the 3 special permissions. | ||
| - | ===== Undefined Permissions ===== | + | Also [[interoperability|not all Unix SFTP servers]] are able to set the special permissions. |
| - | When explicitly changing permissions of existing remote files, the checkboxes can be set to undefined (grayed) state. It means that the particular permissions should be left to its current state. This is useful when you was to change one particular permissions for set of files/directories that have different permissions. | + | ===== [[undefined]] Undefined Permissions ===== |

| ===== Octal Format ===== | ===== Octal Format ===== | ||
| - | The //Octal// box shows octal number representation of the permissions set by the above checkboxes. You can enter the octal format directly instead of manualy 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. | + | The //Octal// box shows octal number representation of the permissions set by the above checkboxes.

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. | ||
| + | |||
| + | ===== [[other_options]] Other Options ===== | ||
| + | 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 the [[ui_properties|Properties dialog]], the option is available only when there is at least one directory selected. Also it will not work for [[scp|SCP protocol]] for subdirectories of the selected directories. | ||
| + | |||
| + | The checkbox is disabled, if you check "execute" permissions explicitly for all permission groups, as it makes it effectively useless. | ||
| + | |||
| + | ===== [[s3_acl]] S3 ACL ===== | ||
| - | The //Octal// box is available on [[ui_properties|Properties dialog]] only. | + | With [[s3|S3 protocol]], you can set basic file ACL on [[ui_properties|Properties dialog]].· |
| - | ===== Other Options ===== | + | &screenshotpict(permissions_s3) |
| - | 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-only" permission set already. | + | |
| - | On [[ui_properties|Properties dialog]] the option is available only when there is at least one directory selected. Also it will not work for [[protocols#scp_secure_copy_protocol|SCP protocol]] for subdirectories of selected directories. | + | The rows of checkboxes are used to set/unset specific permissions for the //Owner// (the owner of the file); the //Users// (anyone with an AWS account); and //Everyone// (public access). The label //R// stands for "read permissions for the file", //R ACL// for "read permissions for the file ACL" and //W ACL// for "write permissions for the file ACL". |
| + | Changing permissions of S3 folders is not supported. | ||
