Delete Temp files

[hutch--]

I thought someone may like this as its very simple. Something in my system is dumping tmp files in the windows Temp directory and I end up with far too many in a short period. This is a quick way to solve the problem.

What about using SHFileOperation? This can delete subdirectories as well (I think) or at least recurse through them.
Or maybe a batch file  :bg

Edit later:
If you chdir into windir$() and then chdir into "temp" but "temp" doesn't exist then you will start to delete your windir...

[hutch--]

I already have recursive delete including directories but what I needed in this instance was deleting tmp files in one place so the simple code does exactly what I required.

[sinsi]

Yep, I was just thinking of the "cut&paste" brigade.

Here is a version incorporating sinsi's suggestion to test if the "temp" directory exists first.

I had visions of somebody deleting their windows directory - in XP it might not be too bad,
but in 98 is would be a bit of a problem...

[P1]

I would clean the GetTempPath directory as well.

Hi all!)
Speaking about trash files i found that the following extensions are usually belong to garbage files. U can just try to search them and accurately(!) delete some or all of them. But be careful some files with such extensions are may be important... delete on your own risc...or cisc?;)

Hutch,

I think I was having the same problem you are. Something was cramming acr*.tmp files in my 'C:\Documents and Settings\LocalServer' folder, there were 12 GB of them! I got a warning that my disk was getting full. After much searching on the web I think the culprit is Acrobat Reader (I had 7.05). I ran FileMon on one of the files and 'cidaemon.exe' was reading and writing to the files. 'cidaemon.exe' is part of the Windows Indexing Service. I did a search and most of the stuff I found suggested disabling the Indexing Service. I did that and the problem stopped, but I would rather have the Indexing Service on. I did another search for "acr tmp Indexing Service" and found this on the Adobe Reader Forums. I uninstalled Acrobat Reader (I'm using Foxit Reader anyway) and I turned the Indexing Service back on. So far so good, no more acr*.tmp files.

You don't need the indexing service, it just makes searches faster, but the Windows searching ability is flawed anyway. I have had many problems with that service locking files, which is a real PITA particularly when you are trying to build ASP.Net projects or do automated builds.

sluggy,

Yeah, I have gone back and forth over whether to leave Indexing Service on or to disable it. Some people say that you should disable it, others say that you should leave it on. I have read and heard opinions both ways. I have always decided to leave it on. I may disable it for a while and see how it goes.

This problem I was having was being caused by Adobe Reader. I have been using Foxit Reader and I like it much better, it's smaller, faster and has less negative side effects.
