7Zip is one of the widely used compression techniques similar to Zip compression. 7Zip application creates compressed archives with .7z file format, which is much better than ZIP file format. It uses varieties of algorithms to compress .7z archives. It also decompresses .zip, .rar, .jar, .arj and other archive formats with ease. However, this 7Zip file undergoes various uneven situations after which archive gets corrupt and shows errors; one such error that makes 7Zip file inaccessible is CRC error.

7Zip CRC error:

Every archive file holds a CRC value while zipping the contents and this value will be saved within archive. Again while unzipping archive, decompressing application like WinZip matches calculated CRC value with existing value of that file. If both the values do not match, then it gives way for CRC error. Encountering CRC error message during 7Zip file extraction implies that either contents of file is damaged or altered. There are many reasons that causes CRC error in 7Zip file such as:
