A Utility to Clean Up Compiler Temp Files

A shell extension that deletes compiler temp and intermediate files.

 [DirClean menu items - 9K]

Recently at work, I was talking with a coworker about cool little utilities that we wished we had. He mentioned an idea for a shell extension that would remove all intermediate compiler files (such as *.obj) from a directory (and recurse subdirectories, naturally). That sounded pretty neat, and since he was in the middle of writing up a different cool program, I decided to get cracking on the clean-up utility and see what I could do.

I came up with this little app, DirClean. It's a shell extension that appears on the context menu of directories, and has a "Clean up temp files" command that will remove intermediate compiler files from the selected directory and its subdirectories. By default, the files are put in the Recycle Bin, but you can configure DirClean to just delete the files instead. DirClean uses the SHFileOperation function to delete files, so if there are a lot of files to delete, you'll see the familiar flying-paper progress dialog.

DirClean has both ANSI and Unicode versions. It was written with VC 6 SP 3, and tested on Win 98 and Win 2000.

The "DirClean options" menu item brings up the DirClean options dialog:

 [DirClean options - 9K]

The settings here should be self-explanatory. I don't do any checking of the wildcards you enter, so you probably don't want to enter "*.*" Wink | ;) The settings are saved in HKEY_CURRENT_USER, so each user has his own settings.

Note that you can override the "Send files to the Recycle Bin" setting by holding down the Shift key when clicking "Clean up temp files." Holding in Shift will immediately delete files if you have the option set to send files to the Recycle Bin, and vice versa.

Important note for VS.NET users

On the NT-based OSes, the way that the shell handles extensions of more than 3 characters will cause problems for C# projects. The default behavior of the shell makes the wildcard *.res match .RESX files (it only compares the first three characters), and deleting the .RESX files will delete some resource information.

So, to avoid deleting those files, you can either remove *.res from the list of files to delete, or go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem, and set the DWORD value Win95TruncatedExtensions to 0, then restart your computer. See KB article Q164351 for more info on this feature.


Oct 28, 2001 - Default list of wildcards updated.
Dec 25, 2002 - Added note about the Win95TruncatedExtensions registry entry.

Reinout Hillmann25-Dec-02 22:23
memberReinout Hillmann25-Dec-02 22:23 
There is a logical reason for that (although the reasoning doesn't offer a solution).

If we look at the old short names that windows generates when you create those three files we have:
   Long name     Short name
1)     =  QQQ.RE
2) qqq.rer    =  QQQ.RER
3) qqq.rerere =  QQQ~1.RER
So, it seems as if the DIR command (and other commands) parses using the old and new filenames and makes a union of the results.

For example:
dir *.re    -> This will return 1 result as expected
dir *.rer   -> This will return 2 results since it matches the union of the long names and the short names
dir ???.rer -> This will return only 1 result.
dir *q.rer  -> Also return only 1 result since it won't match row 3

As I mentioned, it's not really a solution to your problem but at least it's an explanation as to why things are happening the way they are. Unsure | :~
