FILE_ATTRIBUTE_ARCHIVE - Win32 file attributes
After getting my resource manager to work, I thought I would change the "search for resource in x folder" code so that it wouldn't look at files it didn't need to ( system files, folders, hidden files, etc. ).
Each file can have an attribute of one or more of the following:
FILE_ATTRIBUTE_ARCHIVE
FILE_ATTRIBUTE_COMPRESSED
FILE_ATTRIBUTE_DIRECTORY
FILE_ATTRIBUTE_NORMAL
FILE_ATTRIBUTE_HIDDEN
FILE_ATTRIBUTE_READONLY
FILE_ATTRIBUTE_SYSTEM
FILE_ATTRIBUTE_TEMPORARY
So, naturally, I do a check on each file to see if it has the attribute FILE_ATTRIBUTE_NORMAL. My manager immediately stopped finding any of the textures I told it to look for.
After much hair pulling and cursing (yay for comparing integers to #defines) I discovered that all my resource files had an attribute of FILE_ATTRIBUTE_ARCHIVE. These are all images I created in GIMP.
I am at a loss as to why they are considered archives. Maybe it has to do with the fact that the folder they are in was originally extracted from a zip file ( although, as I stated, the images themselves were created with GIMP ).
MSDN's description of FILE_ATTRIBUTE_ARCHIVE is:
"The file is an archive file. Applications use this attribute to mark files for backup or removal.", which is, in my opinion, wonderfully vague.
I know I've made a check for FILE_ATTRIBUTE_NORMAL in previous code and it worked fine.
So my code is working, and I'm not complaining, but I was just curious as to why my files might have this attribute. If any of you could shed some light on this, I would be grateful [smile].
FILE_ATTRIBUTE_ARCHIVE doesn't mean the file's a archive. It is (was?) used for backups and it's purpose is to mark a file as "archived" or not (so you know which files has changed since the last backup). If they were extracted from a zip it's possible they are marked as archived. I don't know if this "arhived flag" is used anymore.
I've seen drawing programs saving images with Archive attribute (MSPaint, Photoshop, CorelDraw for examples).
I think this is a 'hidden' rule between programmers, as Microsoft said Archive files are ready for archiving (in Windows NT there is a built in utility - I don't remember the name - automatically compresses Archive files and delete unnecessary stuff). Images is probably considered safe to compress.

The archive attribute is not particularely useful nowadays. Basically in old days once a file was backupped its archive flag was removed. Once the file was modified it got the archive flag set marking it as need-to-backup.
I'd rather go the exclusive approach and ignore all files with the unwanted attributes like system file/folder or others.

Yeah, I know the file isn't actually an archive - that's the weird part.
I also realized that a file I am writing using my resource manager is marked with FILE_ATTRIBUTE_ARCHIVE.
Its just strange that I've done this before and never ran into this problem.

That is possible, especially considering the amount of backward-compatibility code in the windows API.
Thanks for the reply.

Ah, that clears it up a bit. Thanks!
@Skeleton_V@T: That makes sense.
Now I know to be aware of this in the future. Thanks for all the replies.
