Thread: Can't delete Thumbnail Cache under Windows 7

Hi,

under Vista, i used to delete my Thumbnail Cache files :

AppData\Local\Microsoft\Windows\Explorer\thumbcach e_32.db
AppData\Local\Microsoft\Windows\Explorer\thumbcach e_96.db
AppData\Local\Microsoft\Windows\Explorer\thumbcach e_256.db
AppData\Local\Microsoft\Windows\Explorer\thumbcach e_1024.db
AppData\Local\Microsoft\Windows\Explorer\thumbcach e_idx.db
AppData\Local\Microsoft\Windows\Explorer\thumbcach e_sr.db

with the following Code:

Code:

if ( !DeleteFile( filesC.Item( i ) ) )
{
	DWORD dwAttC = GetFileAttributes( filesC.Item( i ) );
	dwAttC &= ~( FILE_ATTRIBUTE_READONLY );

	SetFileAttributes( filesC.Item( i ), dwAttC );

	DeleteFile( filesC.Item( i ) );
}

after restarting explorer.exe, those files are automatically regenerated.

Under Windows 7 this is not the case, those files are not deleted or regenerated even after restarting the system.

Am i missing something, or there is some way to notify explorer.exe to delete those files?


Thanks in advance.

Under Vista:

-The first call to DeleteFile returns 0, and GetLastError returns ERROR_ACCESS_DENIED.
-After changing the file attribute, DeleteFile returns non-zero value(success).
-Thumbnails are regenerated automatically after restarting explorer.exe.

Under Windows 7:

-The first call to DeleteFile returns 0, and GetLastError returns ERROR_ACCESS_DENIED.
-After changing the file attribute, DeleteFile returns 0, and GetLastError returns again ERROR_ACCESS_DENIED.
-Thumbnails are not deleted or regenerated even after restarting the System.

Under Windows 7 this is not the case, those files are not deleted or regenerated even after restarting the system.

-Thumbnails are not deleted or regenerated even after restarting the System.

I don't get it. If you can't delete the files in the first place, how would you know wether or not they get re-created??

As for deleting them, try blanking out the file's security descriptor before deleting and see if it works.
