No, you cannot repair 7zip files using Remo Repair Zip software. The software doesn't support repair of 7z (7zip) files, it only supports repairing corrupt ZIP and ZIPX file types. And it also repairs split Zip files.
Once the repair process is completed Remo Repair Zip software would display a window, which displays all the recoverable items in the Zip archive. You could check file name and its corresponding size of each and every file that is present in the ZIP archive.
According to this information, you can judge whether Remo Repair ZIP repairs your corrupted Zip archive. If you are satisfied with the results you could purchase the software to save the repaired ZIP file.
The internal data and structures of split Zip files are identical to those of spanned Zip files. The only differences between them are the names of the parts, that is:
Each part of a split Zip file has a different extension (such as 'mysplit.z01', 'mysplit.z02', etc., and 'mysplit.zip' for the last part). While all parts of a spanned Zip file have the same name (such as 'mysplit.zip').
Please follow the below mentioned procedure to repair your split Zip files:
