corrupt zip archives

[lionstorm]

Hi all,
I download sword of sodan HD from BTTR and when I extract it on my A1200 with Unzip5.42 I got error message telling disk1 and 2 are corrupted. How it is possible ?

will download the file again. Problem is how can I be sure that all my already downloaded files are all right ? Is there a good program that will let me check the archive integrity of all files in one go ?

@ Steady : BTTR is the biggest legal amiga emulation site so files from them are probably checked and rechecked before their get released so I am surprised to get corrupt archives.

I download the file again and did a check under winzip : no error. I then checked the corrupt archive and the test option is seeing errors. So maybe it was a DL error (strange because I never have to resume since the connection at work is very fast 50-100kb/s).
BTW do you always shift and click when you DL a file ? I dont and it works fine until now so maybe this shift enable may help me ??
