freespacer perfect clean disk space on Windows 98 XP 2000 russian software

If you end up with a low disk space, or a lot of broken shorcuts without knowing how this exaclty happened  on  Windows XP and you need to free some disk space on OS without manually bothering to delete Windows Temporary files. Check out a tiny Russian Program called Free Spacer. The program is a good substitute for the inefficient windows default app Disk Cleaner. Free Spacer is FreeWare and it can be just used "as it is" but unfortunately access to source code is unavailable as well as use for commercial purposes is prohibited.

I've used Free Spacer multiple times on messed up PCs and always it does good, it is an excellent piece of software. Any Windows-Admin knows  Cleaning some disk space from unnecessary junk files, makes PC work faster. Free Spacer is very useful to run on Virus infested PCs, together with SpyBot , Malware Bytes and some AV soft like Avira.

As software is Russian, unfortunately menu buttons are in Russian too. Even non-russians can easily orientate as the most important buttons are first two from up to bottom and the last which is exit. The first button on from top onwards starts searching for garbage and obsolete and temporary files you can afterwards delete with the second button Удалить – meaning Delete in Russian). A note to make here is on newer Windows than XP Pro or XP Home FreeSpacer does not work well; even though it installs and runs on x86 Windows Vista and Win 7 it hangs up during scan.

For latest version of FreeSpacer check Free Spacer's Official version here, only available in Russian. As of time of writting this post FreeSpacer's latest version is 1.67, I've created mirror of FreeSpcer 1.67 here.

Here is description of what FreeSpacer "features" translated to English:

  • Powerful cleaner drive of unnecessary files.
  • Cleans efficient found "garbage." files
  • A large number of masks for the detection of unnecessary files / folders.
  • Cleanup folders with temporary files, not only Windows / Internet, but about 30 popular programs.
  • Search for invalid shortcuts.
  • Search system restore points.
  • Search for missing files and folders.
  • Support Exclude files and folders.
     

Is it possible mail server to work on alternative port to 25?

Thursday, February 28th, 2013

If you're running a small home based Linux or BSD server with Qmail, Exim or Postfix and it happens your ISP has filtered incoming connections to TCP/IP port 25 and you wonder if it is possible to use other alternative port to 25 for example the (Secure SMTP) SMTPS 465 supported by all major SMTP servers, the answer unfortunately is it is not possible.

The only accepted and working mail transmission port works on TCP/IP Port 25, thus the only option to make the mail server working fine is contact your ISP and convince them to remove filtering for port 25 to your custom IP. Many ISPs set a Firewall filter for 25, because nowadays many Windows XP / Vista / 7 PCs get infected with Viruses and Trojans running a tiny SMTP server on the host and trying to send million of SPAM messages via the poor unknowing victim. This congests the network and often even creates ISP network overloads, thus ISPs prefer to filter Port 25 to get rid of such eventual problems.

Once again,  alternative port to 25 for Mail is impossible !
