File.Delete - temp folder?

[Robert Barton]

Hi all,

I am trying to incorporate the file.delete function into a macro and am
able to get it to work if I use an "ImageJ" directory somewhere along the
path, but it will not work if I use a "temp" folder.  I have
tried "temp", "tmp", "Temp", and "Tmp" with no luck.

It is not imperitive to change it, but would make my files less confusing
for someone else who may be using them.

Also, is it possible to bypass the "1" that signifies that the file was
deleted?

Thanks

Hi Robert,

As written in the documentation, for deleting the file must be
in one of these
  - (1) in the user's home directory
  - (2) the ImageJ directory or
  - (3) the temp directory.

Actually, any directory with "ImageJ" in the path will fulfil
(2), so you can delete, e.g. /disk2/data/ImageJdata/myimage.tiff

The temp directory for (3) is the one you get with
getDirectory("temp").

To avoid the "1" in the log Window, assign the result to a
variable:
   success = File.delete(myPath+myFilename);
or
   if (!File.delete(myPath+myFilename)) exit("Delete failed");

If you didn't want the directory in one of the three locations Michael
listed, you could probably use the exec() function instead.  It
executes a system command, and the limitations would be dependent on
the user's permissions.

Linux
exec("rm", "path");

Windows
exec("cmd" , "/c" , "del", "path");
