You can delete most files except system files which are .exe and .dll (in Windows folder for example).\n\nI will delete large video/DVD files if I do not like them or watched already, maybe after backing them up on DVDs.

Yes, if you have Windows XP you open up Start>>all programs>>Accessories>>system tools>>Disc cleanup\n\nwhen that opens up it will show you everything you can get rid of. You will want to get rid of the temporary internet files. You can view them before you delete them if you like.

1.  Start --> search --> all files and folders.\n2.  Type in name of file you want to delete.  You don't have to add the extension (.exe, .txt, .doc, and so on).\n3.  In drop down menu select My Computer\n4. In advanced options make sure there's a check mark next to Hidden Files and Folders;  System Folders;  and Subfolders\n5.  Click on search.  When search is finished, delete all files and folders found.\n6.  Restart computer.\n\nIf you're truly brave, delete registry entries.  (It's a lot easier to use CCleaner and safer.)  But if you're brave.....\n\n1.  Start --> Run\n2.  Type in "regedit" (without the quotes) --> OK\n3.  The registry page will open.  Hold down CTRL key and click the letter F\n4.  Type in the exact same file name you used in step 2, above\n5.  Click Find Next\n6.  When a registry item is found, click DEL (or delete key) and answer YES when warning appears\n7.  Click F3 key (top row of keyboard) --> Find Next.  If another item is found, click DEL --> YES --> F3 --> Find Next\n8.  Keep doing that until it says registry search is finished.\n9.  Close out registry screen and reboot.\n\nNOTE:  If you aren't absolutely sure about messing with the registry. DO NOT DO IT!!  Deleting the wrong item can  cause your computer to become unstable or crash.  CCleaner is a lot easier and safer.

Go into my computer and in the address bar put in %temp%\nthen when all the temp files come up highlight all of them and press delete and off they go GONE\n\nAlternatively go onto search and choose my computer and put in the following:   *.tmp,*.chk,~*.* \n\nExactly as i write it - this will delete all temp,check files and other rubbish.  When the search is complete do Control A and delete the lot = ALL GONE

The answer is that you can safely delete everything in that folder. It is the place where all the programs you have ever installed leave garbage, like installers and logs of activity.\n\nIf you are new to this sort of thing, try to find your Temporary Internet Files, which are a cache of all the web pages you have ever visited that make your computer load web pages faster. They suck disk space if you don't clean them regularly, and if you don't want a list of EVERY site you visit on your computer you have cause for concern. They'r hidden here: \nC:&#92;Documents and Settings&#92;{Insert Your User Name Here}&#92;Local Settings&#92;Temporary Internet Files\n\nIgnore the drive D thing. That's probably Windows Recovery, which mirrors your regular architecture so you can restore the whole thing if you do something foolish, like delete the whole Temporary folder and not just the contents.

I use a CCLEANER daily.  It can delete temporary Windows and IE files, as well as detect and remove useless/old/unused registry keys and entries.  The software is free and is updated regularly.  I highly recommend it, even if it's not exactly what you're looking for in this post.  It's just a good day-to-day maintenance application to have.
