100,000 temp files ???

[cybmole]

running a defrag with calibre idling in system tray.

I note a lot of temp files being defraged & check app data .. local...temp.

I see 8 x calibre folders - 4 with 7.40 in the name, 4 with 7.42.

each of the 7.42.... folders contains 25,000 files -

I have done several conversions today but 25000 files ??? - should the program not clean up after itself ?

e.g. - paste from properties - 25,427 Files, 12 Folders
what is all that about ?
I force calibre to close completely as next test, but there is still one folder with 25000+ files in it!

As long as calibre closes cleanly, temporary files used by that instance of calibre are removed.

i guess I never normally close it - I have the PC sleep, not shut-down & I have calibre "close" to system tray.

so they build up over time, I close it only to do program updates.

It's no big deal - I probably have other things that wipe all temp files over a certain age which get run regularly.

but wiping temp files after a conversion ends rather than only when program is closed may be better housekeeping ?

and clearing old temp folders when program first starts would take care of stuff left by previous crashes or forces shutdowns.

PS nitpicking even more! - I think it removes files but leaves temp empty folders

I did zap calibre with task manager a couple of times in the last few days, when I overloaded it & sigil, playing with pdf conversions after 7.42 release, so that would have boosted the number of stray temp files I guess. there was I think 156MB of calibre temp file space, and 4 x 25,000 individual files in local temp folders

I have noticed the same problem with empty folders in ...\user...\temp directory. UNTIDY! Had to tell external program to wipe them.

I always close my Calibre nicely. And yet it never cleans those temp folders...

In case it sheds any light on the situation, I just opened calibre and closed it again immediately.

These zero-length files were not deleted. I then rebooted the PC, the files were still there.

I'm using Windows XP SP3 in case it's relevant.

I start up calibre from a batch file and never have to worry about old temp files or folders.

My way of handling temp files is to get rid of them daily. I'm aided in this by the fact that I don't run calibre round-the-clock in the systray. I normally update and add whatever books on Saturdays while giving my Kindle a charge-up at the same time. For me, I do a backup every day using Drive Snapshot. Drive Snapshot will empty the recycle bin. So, I use EmptyTempFolders and CCleaner to take a double-pass at getting rid of temp files that might be scattered about. I have, at last count, seven folders on C: alone called Temp. ETF2 does a good job of hacking away at those. CCleaner is a good fail-safe for ETF2 and gets at a few other places ETF2 isn't set up for.

So, my daily backup batch file, run at the ungawdly hour of 8:01am, has these lines at the beginning:

cd \apps\utils\EmptyTempFolders
emptemp2.exe /all
cd \apps\utils\CCleaner
CCleaner.exe /auto

Obviously, Dwanthy's version is really quite good, requiring no third-party software. But it IS Calibre-centric. My version, with the freely available third-party freeware, is more of a blunderbus approach, which might clean out more stuff, while giving up on getting stuff back out of the recycle bin if you discover the deletion a day late. (Which is why I keep 31 days of complete backups on NAS's and have a Carbonite Pro account).
