FilePermissions Property

A 32-bit integer containing the a POSIX-compatible file permission bitmask.

Syntax

property FilePermissions: Integer;

Default Value

0

Remarks

A 32-bit integer containing the a POSIX-compatible file permission bitmask.

The bitmask should be interpreted as a decimal value of a series of octal digits. For example, a octal permission value of "100644" would be "33188" in base-10, and "40755" in octal would be "16877" in base-10.

The last three octal digits are the most significant and represent, in order, the file access capabilities of the file's owner, the owner's group and other users. Each of these octal digits is, on its own, a 3-bit bitmask with the following possible values:

An octal permission digit of 7 would have all three values set and would mean that the file can be read, written and executed by that user class. For example, the octal permissions "100644" would have a value "6" for the owner, "4" for the group, and "4" for other users. This would be interpreted to mean that all users can read the file, no users can execute it and only the owner can write it. The permissions "40755" would mean that all users can read and execute the file, but only the owner can write it.

The previous octal digit is another bitmask with the following values:

The previous two octal digits are used together as a bitmask to determine the type of file. This bitmask has the following values:

For example, the octal file permissions "100644" would indicate a regular file and octal "40755" would indicate a directory.

Please note that you will need to convert the octal permissions bitmask into its decimal representation
