rar instead of 7z

Let me give an example. 

On my usb 3 drive, if i unzip a .7z game that is a little over 1Gb, it takes over 1 minute to unzip with 7zip.

If I zip the same game with winter using rar5 format, it take winter only 14 seconds to unzip it!

7zip can't even extract a rar5 format, so i can't use 7zip for that. 

this is a HUGE time savings un the decompression wait.

however, i just tested and found that if i zip all the iso files using the "rar" (not rar5) format, 7zip can unzip them and it only takes 16 seconds!

so, the end result is that 7zip is fine. the HUGE savings here is just zipping up everything with winrar using rar format.

win !!

guys, i wasn't suggesting LB to use, include, or set rar or any other program. i was just asking for LB to have an OPTIONAL setting to allow us, the users, to specific any unzipping program and parameters we want, so that if someone owns Winrar they would have the option to tell LB to use their rar program in their program directory with their command line unzip parameters. it would only be an option and 7zip would still be the default with LB.

anyway, from my experiment i found it is OK to just keep using 7zip only for unzipping. the super fast performance improvement is to rar all your game images using rar and .rar extension and compression. 7zip can extract a rar (not rar5) format OK. the difference in unzipping speed is phenomenal.

i got a batch file script from the Rocketlauncher forum to automatically unzip and rezip all my .7z gamecube files, using rar.exe program and rar format. i own Winrar, but you could also just use the trial of it for this purpose.

again, the speedup is amazing. wish i found out about it before.

I decompress rar5 just fine with 7zip all the time. 7zip added suport for it late last year

I believe you, but I tried zipping with rar5 using the very latest Winrar program and then unzipping it with 7zip and 7zip told me it could not. But it could deal with the regular rar compression.

You should *.zip them, that's even faster, haha!  ^^

I don't know what you mean? i am rezipping my 7z files (that were not zipped with rar format) using the rar format. that's the only way i know of to get a fast unzip.
