> Roman I do already have BOTH options on.

The first option is zip only. If the second option doesn't report any error, the file (the data of the compressed file, not the archive) is valid.

You talk about 7z files here, not good old zip. 7zip (and esp. its SDK) is a lousy format when it comes to checking structures or caring for standards. You shouldn't check it with Winrar either. The sdk and so cmpro doesn't check for corrupt structures in 7zip files. If cmpro is able to decompress the file and check the crc and reports it as valid, the data is valid and rebuilding it to zip will create a fine file.

If you need 7z structure scans, complain to the sdk authors. You can send me one of the bad files and I may have a look at it if it's even possible to capture such things. To sum it up: nothing really to worry about.
