Delphi: Hide Files

Question by Guest | 2012-09-17 at 21:00

I need a Delphi code to hide a file. Is that possible with Delphi?

It would be helpful, because otherwise, I have to click on each file individually with my mouse to select "hidden". So, hiding would be really easier by using Delphi.

That is possible with Delphi.

Just try out the following code:

FileSetAttr('C:\dat.txt', faHidden);

With this, you hide the file "dat.txt".

Alternatively you can also take the following code to hide the file:

fname := 'C:\dat.txt';  //fname is a string variable

if (FileGetAttr(fname) and faHidden) > 0 then
  FileSetAttr(fname, FileGetAttr(fname) xor faHidden);

And the following to undo the invisibility again:

FileSetAttr(fname, FileGetAttr(fname) or faHidden);

If you are using the two last codes, any other file attributes (such as read-only) will be kept. The first method, however, overwrites any other former attributes of the file.
