Windows 95/98 : To delete all of those temporary internet files and hidden index.dat files that store your cookies and surfing history, insert the following into your autoexec.bat file : DELTREE /Y c:\windows\applog\*.* DELTREE /Y c:\windows\cookies\*.* DELTREE /Y c:\windows\history\*.* DELTREE /Y c:\windows\recent\*.* DELTREE /Y c:\windows\temp\*.* DELTREE /Y c:\windows\tempor~1\*.* Another way to do it is to make a .bat file, like tempfiles.bat and put the above commands in it. Then put c:\tempfiles.bat (assuming you saved tempfiles.bat in the c: directory) into the autoexec.bat file. NOTE: Whatever commands you put into the autoexec.bat file, try not to put it first or last. If you have only one command in autoexec.bat, then put it last. If you're pretty paranoid about the sites you've visited being on your hard drive, remember this: temporary internet files are written to the hard drive and even if you delete them they are still written onto your hard drive, and could potentially be recovered with an undelete program. Also, all of your surfing history is copied to hidden index.dat files which are not deleted when you supposedly delete the temporary internet files. Windows ME / NT 4.0 / 2000 : 1. Make file xxx.bat (use notepad etc.) and write into it: DELTREE /Y c:\windows\applog\*.* DELTREE /Y c:\windows\cookies\*.* DELTREE /Y c:\windows\history\*.* DELTREE /Y c:\windows\recent\*.* DELTREE /Y c:\windows\temp\*.* DELTREE /Y c:\windows\tempor~1\*.* 2. Save it in c:\ 3. Open "My computer" and pick that "xxx.bat". Then choose "properties", "program" and enable "close on exit". 4. Run Regedit, and go to "HKEY_LOCAL_MACHINE \SOFTWARE \Microsoft \Windows \CurrentVersion \Run" and "new - string value" [name it to:"xxx"], set its value to "c:\xxx.bat". 5. Close regedit. Windows XP : 1. Make file xp.cmd (use notepad etc.) and write into it: cd %homedrive%%homepath% rd /s/q locals~1\tempor~1 rd /s/q locals~1\temp rd /s/q cookies rd /s/q temp rd /s/q locals~1\temp\history rd /s/q locals~1\temp md locals~1\temp 2. Store the xp.cmd file in your startup folder. 3. Reboot your computer. Your paths may be different than mine so be sure to check them first.
