[Gambas-user] Acting on a file in the local folder of a Gambas project

[Bruce]

Hi Vuott,

The answer lies in understanding the difference between relative and
absolute paths in the gambas runtime.  There is some help at
http://gambasdoc.org/help/cat/path?pt&v3 

Some comments inline below

Here you are using a relative path to a file inside the executable, not
the file in your source directory. So, as per the pemissions revealed by
your Print Stat(..) below, you can Copy it somewhere else.

Yes because the permissions for the file inside the executable are read
only and Move, i.e. Copy + Delete cannot be achieved.

Here you are using an absolute path, i.e. your source directory, and as
per the second Stat below you do have Write access to that real file.

Again, the relative path means that you are trying to access the file
that has been compressed inside the executable and no write access is
allowed.

As per the first example.

Again, the absolute path means this is trying to save the real file
inside your source project.
