Unnecessary Files to Delete

When you install (or upgrade) to Windows 95/98, there are many files placed in your root and Windows directories that can be deleted. These are temporary files, or files that are no longer in use by the operating system. These include:

In your Windows directory:

Any files with the following dates can also be deleted, for they belong to old versions of Windows:
03-10-92 - Windows 3.1
09-30-92 - Windows for Workgroups 3.1
11-01-93 - Windows for Workgroups 3.11
12-31-93 - Windows 3.11

In your Windows\System directory:

The entire WIN32S directory under your System directory - this is used only in Windows 3.x to allow certain 32-bit applications to run, but some older applications errantly install it in Windows 95. If you remove this directory, make sure to remove any references to it in your SYSTEM.INI file, and restart Windows 95.

In your DOS directory:

Windows 95/98/NT (not 3.1) don't use the old version of DOS. The DOS directory is probably just taking up space. If you try to use the executable files in that directory you will probably get a message that will tell you that it is the wrong version. I've done just fine after erasing the whole DOS directory. Do NOT erase the DOS directory if you are using Windows 3.x!!!

In your Temp directory (usually Windows\Temp):

The temp directory is used as programs are opened and closed. This directory "should" be empty every time you restart your computer. This isn't always true, however, and there will be scrap files left there. Check the dates of them and as long as they are at least 1 day old, they can safely be deleted.

Anywhere on your system:

Anything with the extensions:

"TXT" - They are usually readme.txt files that only explain how to use a program. Once the program is installed and you are using it, these can usually be deleted.

"TMP" - These are temp files that are usually in the c:\windows\temp directory but they can be elsewhere. If the program isn't in use, then the temp files can be deleted.

"AVI" - These are little movies that are installed that can show you how to do certain things. You probably didn't know they were even there, so you probably don't need them. Be careful though as they might be required by certain programs.

"BAK" - These are backup files that are created when a more up to date file is installed. As long as everything is running fine, then these can be deleted.

"PRV" - These are similar to backup (BAK) files. As long as everything is running fine, then these can be deleted.

"LOG" - Log files are only useful if you are technical minded and you want to see what commands were used when certain things were run. For most people these are useless and can be deleted.

"OLD" - These are similar to backup (BAK) files. As long as everything is running fine, then these can be deleted.

"- - -" - These are similar to backup (BAK) files. As long as everything is running fine, then these can be deleted.

"000" - These are similar to backup (BAK) files. As long as everything is running fine, then these can be deleted.

"001" - These are similar to backup (BAK) files. As long as everything is running fine, then these can be deleted.

"DOS" - These are similar to backup (BAK) files. As long as everything is running fine, then these can be deleted. (unless you use the dual-boot feature)

"WAV" - These are sound files that can be deleted if you don't like all of the "cool" sounds that you hear when you maximize and minimize programs. I would suggest moving these to a temporary directory just in case you miss the sounds.

If you don't plan on uninstalling Windows 95, you can delete WIN95UNDO.DAT (if it's there).

Other files that can be deleted include MSCREATE.DIR. Any directory named, ~MSSETUP.T or msdownld.tmp. If you use WS_ftp, your hard drive might be littered with ws_ftp.log files. They can all be deleted as well.

In your Help sub-directory of the Windows directory, all *.GID files can be erased.

Image files can take up a lot of space. Do a search on your hard drive for *.BMP, *.JPG, *.GIF, *.TIF, and other image files. View them and erase all of the ones you don't want. The Windows directory will have quite a few BMP files as they are used for wallpaper.

You generally don't want to delete EXE, COM, or BAT files as these are programs.

Files NOT to delete:

Anything in your SYSBCKUP directory.
Your Registry (SYSTEM.DAT, SYSTEM.DA0, USER.DAT, USER.DA0), as well as SYSTEM.1ST, which you can use if the first four become corrupted.
Any files in your root directory not mentioned above.

If in doubt:

If you're not sure if something should be deleted, try moving it to another directory first to see if it makes a difference.
Check the file's date - if it's recent, most likely it's still being used.
For information on removing a particular application, contact the manufacturer of that application, or refer to the application's documentation.
