| The OutputFileAttributes property allows to specify the file attributes for file which being downloaded to location specified in OutputFileName property.
|
|
|
| There is 2 "sub-properties": Complete and Incomplete.
|
|
|
| Incomplete property specifies flags for incomplete file which still being downloaded (or paused, but still not downloaded to local drive completely).
|
|
|
| Complete specifies attributes which being set to the OutputFileName once the download finished and file completely downloaded.
|
|
|
 You can use this property to make difference between complete and incomplete files for other application, or to quickly determinate whether local file has been completely downloaded.
|
|
|
| Also, anyway you will be able to rename the downloaded file and change its file attributes (using SetFileAttributes WinAPI), in the OnDone event handler.
|
 atrTemporary and atrOffline options has no effect in Win95/98/ME. These options are only for NT-family systems. You can set it but they will work only in NT/XP etc.
