About the prevention and resolution of compressed files can not be opened

compressed files downloaded from the network, most afraid of failure to decompress or decompression, usually divided into two cases: one is to decompress passwords Correct, there is another kind of CRC error. The CRC error is also called the cyclic redundancy check code error. The main reason is the network transmission problem, or the RAR compression package is inherently damaged, and then it is because of the download tool problem (downloading to 99% is no longer transmitted, manual operation is over ). To avoid CRC errors we can create a restore record for important compressed files, which reduces the chance of CRC errors.

Step 01Open the compressed file, select the "Settings" option in the "Options" menu bar, then in the new pop-up settings window, you need to enter the "Compression" tab, under the tab there is a " Click on the "Create Default Configuration" button in the "Compress Configuration" setting.

Step 02 will then pop up a window called "Set Default Compression Options", go to the "General" tab, there are quite a few compression options in the lower right part of the tab, check Select "Add Recovery Record", then go to the "Advanced" tab, set the percentage in the recovery record to 3%, and then click "OK" to be OK.

Step 03 If you are downloading a compressed file from the network, and the compressed file has no recovery record, you can only gamble on luck. Open the compressed file, click "Extract to", and check the file that keeps the damage in the pop-up window" to skip the WinRAR warning window and see how many files can be pressed. As long as the damage is not serious, the probability of normal use is also Very high.
