Gibt es eine Funktion, die für ein Datei-Attribut den/die Buchstaben/Zeichen liefert, die Windows für dieses Attribut verwendet.
Für die gängigen Attribute sind die mir bekannt, aber für einige bin ich nicht fündig geworden.
Ich weiß, dass für einige (viele) Werte keine Konstanten definiert sind.
Die Frage ist, was zum Beispiel im Explorer angezeigt wird, wenn eine Datei solche Attribute hat.
Könnte ich vielleicht herausfinden, indem ich für eine Datei diese Attribute setze.
Allein: Wollen hätte ich gern gewollt, aber dürfen hab ich mich nicht getraut.

In der nachstehenden Tabelle sind die mir nicht bekannten Zeichen = '?' gesetzt - um die geht es mir.

Hi,

Zitat:

Is there a function that returns the letter/characters that Windows uses for a file attribute?

I don't recall seeing such thing.

One thing though, where did you get these letters from ?
I mean this part might be wrong, ( i think !! )

Code:

     
      ,(Bit:9; Attribute:512;      Text:'P'; LongText:'SparseFile')  // ??
..........
      ,(Bit:19; Attribute:524288;   Text:'?'; LongText:'Pinned')     // should be P
      ,(Bit:20; Attribute:1048576;  Text:'?'; LongText:'Unpinned')   // should be U

from here https://learn.microsoft.com/en-us/wi...ommands/attrib


on side note : files can be pinned and unpinned at the same time.
also found this (by searching) https://ss64.com/nt/attrib.html

The one that is really i don't understand what it does is this one

Zitat:

{+\|-}b Sets (+) or clears (-) the SMR Blob file attribute.

As i can't find any helpful resource about it, and why if possible a local file can have it !? yet, on my PC it only report "Invalid switch - +b", like i am not allowed to change this attribute or even access it.

Thank You, Kas Ob.

I got the "P" for SparseFile from the Windows-Explorer.

Pic1.jpg (Own Application) shows for a file that Bit 9 (SparseFile) is set.
Pic2.jpg (Windows Explorer) shows for that attribute for that file a "P"

Thank you, Amateurprofi !

Now the question is :
How your Explorer will report the Pinned and Unpinned bits ? and how it will change when the file is sparse one ?

Here what i see here

Also i tried the steps from here https://superuser.com/questions/5088...file-attribute yet my Explorer didn't show any letter for the sparse file, even though the file is marked with sparse attribute, my Windows 10 didn't show any special letter for it.

And found two more letters
https://en.wikipedia.org/wiki/File_attribute

Zitat:

Not Content-Indexed (I): When set, Indexing Service or Windows Search do not include the hosting file in their indexing operation.
Reparse Point (L): The file or directory has an associated re-parse point, or is a symbolic link.
Offline (O): The file data is physically moved to offline storage (Remote Storage).

///// ??? again this ???
Sparse (P): The file is a sparse file, i.e., its contents are partially empty and non-contiguous.

I and L can be seen with link files like the directory "Cookies" in your user directory.

Yes.
Pic3 and Pic4 show Users/Defaults/Cookies in my Application and in the Windos-Explorer.
