Indeed it is a great blog on RAR. I have a providers contract and if I want to create a 100000$ as the total contract value and if I want to recognize every year if I want to recognize 10000$ as revenue every year how will I make it happen at the contract level? Do I need to make a configuration change for this integration to happen automatically.
When I wrote Today is "Support Your Favorite Small Software Vendor Day", I made a commitment to spend at least $20 per month supporting my fellow independent software developers. WinRAR has become increasingly essential to my toolkit over the last year, so this month, I'm buying a WinRAR license.Sure, ZIP support is built into most operating systems, but the support is rudimentary at best. I particularly dislike the limited "compressed folder wizard" I get by default in XP and Vista. In contrast, WinRAR is full-featured, powerful, and integrates seamlessly with the shell. There's a reason WinRAR won the best archive tool roundup at DonationCoder. And WinRAR is very much a living, breathing piece of software. It's frequently updated with neat little feature bumps and useful additions; two I noticed over the last year were dual-core support and real-time stats while compressing, such as estimated compression ratio and predicted completion time.WinRAR fully supports creating and extracting ZIP archives, so choosing WinRAR doesn't mean you'll be forced into using the RAR compression format. But you should use it, because RAR, as a compression format, clobbers ZIP. It produces much smaller archives in roughly the same time. If you're worried the person on the receiving end of the archive won't have a RAR client, you can create a self-extracting executable archive (or SFX) at a minimal cost of about 60 KB additional filesize.RAR also supports solid archives, so it can exploit intra-file redundancies. ZIP does not. This is a big deal, because it can result in a substantially smaller archive when you're compressing a lot of files. When I compressed all the C# code snippets, the difference was enormous:ZIP229 KBRAR73 KBBut even in an apples-to-apples comparison, RAR offers some of the very best "bang for the byte" of all compression algorithms. Consider this recent, comprehensive multiple file compression benchmark. The author measured both compression size and compression time to produce an efficiency metric:The most efficient (read: useful) program is calculated by multiplying the compression time (in seconds) it took to produce the archive with the power of the archive size divided by the lowest measured archive size.2 ^ (((Size/SmallestSize)) - 1) / 0.1) * ArchiveTimeThe lower the score, the better. The basic idea is a compressor X has the same efficiency as compressor Y if X can compress twice as fast as Y and resulting archive size of X is 10% larger than size of Y.
every little thing every best single 3 rar
And sure enough, if you sort the results by efficiency, WinRAR rises directly to the top. Its scores of 1871 (Good) and 1983 (Best) rank third and fourth out of 200. The top two spots are held by an archiver I've never heard of, SBC.WinRAR and SBC 0.970 score very well on efficiency. Both SBC and WinRK are capable of compressing the 301 MB testset down to 82 MB [a 73% compression ratio] in under 3 minutes. People looking for good (but not ultimate) and fast compression should have a look at those two programs.The raw data on the comparison page is a little hard to parse, so I pulled the data into Excel and created some alternative views of it. Here's a graph of compression ratio versus time, sorted by compression ratio, for all compared archive programs:What I wanted to illustrate with this graph is that beyond about 73% compression ratio, performance falls off a cliff. This is something I've noted before in previous compression studies. You don't just hit the point of diminishing returns in compression, you slam into it like a brick wall. That's why the time scale is logarithmic in the above graph. Look at the massive differences in time as you move toward the peak compression ratio:72.58%02:54WinRAR 3.6275.24%11:20UHARC 0.6b77.16%30:38DRUILCA 0.578.83%05:51:19PAQ8H79.70%08:30:03WinRK 3.0.3Note that I cherry-picked the most efficient archivers out of this data, so this represents best case performance. Is an additional two percent of compression worth taking five times longer? Is an additional four percent worth ten times longer? Under the right conditions, possibly. But the penalty is severe, and the reward miniscule.If you're interested in crunching the multiple file compression benchmark study data yourself, I converted it to a few different formats for your convenience:Download Excel spreadsheet (36 KB)Google Spreadsheet (view-only)Google Spreadsheet (editable, but need Google login)
Personally, I recommend the Excel version. I had major performance problems with the Google spreadsheet version.After poring over this data, I'm more convinced than ever. RAR offers a nearly perfect blend of compression efficiency and speed across all modern compression formats. And WinRAR is an exemplary GUI implementation of RAR. It's almost a no-brainer. Except in cases where backwards compatibility trumps all other concerns, we should abandon the archaic ZIP format-- and switch to the power and flexibility of WinRAR.
Basically what I'm getting at is in the industry I've been working in 7zip (the program not the archive) is the defacto standard, and is installed on every computer in the office. So I don't really care what archive format it is in.

That lead me to the following question: if anytime I open a rar it caches its content, then is the whole encryption pointless, unless I clear the Temp folders? But does this happen for everything? Is there a safer way to store sensitive information?
Security is hard. While I applaud your attempts to use commonly available programs to increase your security, software that wasn't expressly designed for security often does the little things wrong (as you found out). In your case, your rar program makes a local cache of the contents, presumably so it'll run faster - something that most users would be happy about.
TL;DR: the single best way to protect yourself from data leakage on a personal computer is to use full-disk encryption (or encrypt your user's folder if it's a shared computer), a strong password for your user account, don't share your account with anyone, and make sure you log out (or at least lock your screen) whenever you step away from the computer. Also, turn on your firewall to make sure that programs aren't uploading data anywhere without your permission. That way, even if you are using programs that do the little things wrong, it doesn't matter.
In fact, once it decrypts / unarchives the files and saves them to disk there's really no point in even trying to protect them anymore because every other program on your system can see them. For example, Windows Explorer will index and process the photos in order to display thumbnail previews, leaving cache files behind. And what about actually opening the photos? Which photo viewer will you use? Are you the programmer who wrote it? If not, how do you know that the photo viewer will not make cache files? Or maybe upload your files to the internet? The point is: unless you've personally inspected the source code of every program that's running on your computer (including the OS itself), any one of them could be doing naughty things with your data.
To avoid this kind of surprise, you could use something like Tails: Tails forgets everything you've done once you log out and you didn't expressly copy to an external device. But then, using Tails for daily stuff is such a pain - because most of the time you DO want your computer to remember stuff - that you will give up on it. You should only use Tails for very sensitive "your eyes only" things, but you cannot work that way every day. 2ff7e9595c
