CCleaner: Issues

  VCR97 20:17 24 Oct 04

I have just run CCleaner for the first time on my XP Home/SP1 system. The "Scan for Issues" brought up several "Invalid File Extensions". However, several of them appear to me to be perfectly valid. The all have Registry key

HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\, (extension).

The extensions are $$$ avc bak BTL CH_ dal dtb NET old OVL pf qkt ref OpenWithList.

Can anyone shed any light on this, please? It doesn't do it on my Win98 system.

Keith S I don't know what those entries are, but if you delete them you're offered the choice to make a backup. They're usually leftovers from deleted programs.

Choose 'yes' and if there's a problem you can restore them.

I keep all mine for at least two days but haven't yet had to do a restore.

See if RegscrubXP click here finds the same.

ps I've recently run CCleaner on my new laptop and cleared out quite a few entries that I assume were left there when the techies were setting up the system.

These file extensions are not recognised as valid file extensions.

Don't panic it doesn't delete the file only the entry in the registry, just done it with a .bak file I created during some work.

The files wil work ok when called for by the appropriate program.

Thanks for the responses. It seems that I can probably delete them but I'm puzzled as to how an extension such as .bak can be regarded as invalid.

VoG Regscrub doesn't find any in "Regscrub finds problems".

I wonder about some issues and as a matter of fact do not fix all issues raised only the ones I know need fixing i.e Removed program issue. Although the backup is there I am still apprehensive about fixing all items.
Advise would be appreciated.

Always fixed All Issues never yet had a problem.

but what are the issues that contain the name of programs I still have installed. I just don't understand it enough to have complete faith in it.

I let CCleaner delete the items with backup and all seems well. I'm guessing that "invalid file extension" actually means an invalid instance of use of a file extension. Pity it doesn't say so.
