Issue:

sometimes, we tried to copyclip and paste (ctrl + C and ctrl + V), but ZWCAD responses very slow, sometimes even failed, why and how to solve it?


Reason:

ZWCAD will generate the temp file starts with "Zw$" under the folder %temp%, and the file will not be removed even you close ZWCAD, because you may need to paste it in other CAD. As time goes, the files will be more and more, and it will take time to check the file name duplicate or not, and if the files are too many, the 4 numbers for the file naming will be used up, then it will caused the copyclip failure.


Solution:

Just go to %temp%, and then remove all the files that starts with "zw$", then try again.


Note: since ZWCAD 2022 SP1, the mechanism has been optimized, so this issue doesn't exist since this version.
