Permissions issues for creating files under Windows

1. Under Windows, if a file is created under a directory, the newly created file inherits all permissions from that directory by default ( parent-child relationship )
2. If you move a file from one directory to to another directory, then the permissions of the file do not inherit permissions from the directory but retain the permissions of the original directory .
3. If you copy a file from one directory to another, the permissions of the file will lose the permissions of the original directory and inherit the new directory. ( new re-write )
4. Files uploaded via FTP are also new and re-written as 3

Any permission that is continued cannot be lower or deleted (parent- child relationship ) than the parental permission
However, there are ways to resolve this problem, that is, the relationship between directory and file Inheritance (de-parent relationship)

1. Right-click Properties
2. Click the Security tab
3. Click Advanced
4. Click Change
5. Uncheck "Include permissions that can be inherited from this object's parent"
6. Click Delete
7. Click OK
8. Click Yes
9. Click OK
10. Click OK
