Hello, Regarding the previous, it is best left as is, and perhaps the helpfile changed. EG 2: AddOptions := AddOptions + [AddResetArchive]; // Full Copy, ClrBit 3: AddOptions := AddOptions + [AddResetArchive] + [AddArchiveOnly]; // CopyBitSet&Clear is fine. the helpfile might be changed thus: AddResetArchive Clears the archive bit after a successful Zip Add on all files selected. By including AddArchiveOnly (eg [AddResetArchive] + [AddArchiveOnly]) will only Zip files with bit set, then clear the bit.
