I have a folder with several zip, rar, 7zip, exe files and other folders inside, if I create a single solid or compressed file with all these files and folders inside it will be better to avoid corruption if a problem occurs on the HDD media where this file is saved ex. HDD or SSD and will it also be easier from time to time for me to take this file inside the HDD or SSD and with the help of a program analyze if anything inside it has not corrupted? |

Quote: if I create a single solid or compressed file with all these files and folders inside it will be better to avoid corruption It would also increase chance it would corrupt which would put all of that data inside in jeopardy. If you're so concerned about these things, buy good drives rather than cheap refurbished stuff and use ZFS, it has built in check summing if I am not mistaken. |

So no possibility of creating a unique one without risk of corruption? I don't know of any software that analyzes all these files automatically, you just need to select the main folder and it will analyze them all to show if something has been corrupted. If it was just 1 solid file it would be easier |

Yes, one archive then you'd immediately detect if it's corrupt > congratulations, you have now lost all files inside the archive. No, there's no software that can detect file corruption in random files unless you use check summing. Which is why I suggested a FS with that built-in. |

Do you recommend creating the single solid file or not? ZFS is a program? I don't know it analyzes all folders and files and shows any corruption? i use windows |

The bigger the file, more chances you have that having some bad sectors that corrupt the whole file. Better to have small files. |

The advantage of having a single file is that in a single test I can check if something has been corrupted, if the files are separate I will have to test many files and I may forget to test a file What is the safest way to create an archive and inside it there are folders and files zip, rar, 7zip, exe and others? |

I'd get one of those 4TB AMAZON portable SSDs, then grab all my data, put it on there in a single archive that I'd encrypt twice (better safe than sorry). If you have more than 4 TB data I'd write a single multi-part archive to multiple AMAZON 4 TB SSDs. |

I don't want to compress or compress anything else I just want to generate a single file with all these files and folders inside it 150gb What format do you recommend? 7zip or rar or something else? which software? what compression settings? just these 3 questions |

personally, I would just do a disk image. then super easy to extract files, just mount it. But if you really want to squeeze 150GB down a bit (these days I don't see the need to compress as much) then 7-zip on regular settings is fine. There isn't going to be a great deal of difference between all the different options, or archive software. If you are really hard up for storage, I will send you 30x 500GB laptop hard drives, you just pay for postage! |

I wouldn't rely on rar solid archive, I have found that if a file is damaged, then it is damaged. no fancy tricks will fix significant damage. with all of them you can specify archive compression, but the more compression levels, the slower it will be and less useful or easy to use. seriously, if you need some drives, pay for shipping and I will send some. I have so many I don't know what to do with them. And I will never use them. maybe grab an old PC and make a raid / NAS box or something |

So what format and compression configuration and software do you trust? What is the shipping cost to Brazil? |

the problem is, you will need to keep this archive you make safe from all the same factors as the files you archived up. I generally use z-zip if on windows, but I dont often archive big things. I used to use rar for dumps of devices 1GB - 64GB and make them multiarchive of 100MB ea. not sure there is any real reason to multiarchive anymore actually. this is a rough estimate in AUD Box 22.5 x 31 x 10.2cm Up to 5kg $119.85 |
