Bug? In Icon Cache

[romulous]

Hi,

On my PC, everytime I open TC, it will lose the icons for a particular file extension (for example, .xls files) & rather than displaying the normal icon that is associated with that file extension, it will just display a generic "white window with blue title bar" icon. However, if you double click on the file, it will still open in the associated program, it just displays the icon incorrectly. Once you close TC & reopen it, this extension will be fine, but another will have lost its icon & will display as the generic icon (for example, jpg). Has anyone else noticed this? You can of course go into Files-Associate With & just click ok (this will somehow refresh the display so that the correct icon is displayed), but this is terribly annoying as TC loses the icon for a filetype every time it is opened on my PC. I've noticed this problem on the last few vesions of TC.

Hello!
• I'm using the newest TC 6.02 under Win 98SE and XP-Pro.
• I didn't noticed such a problem. Maybe have you a program running in the same time, like a virus scanner ? In some cases, that could disturb some functions in TC.
• You might watch the icons in Win Explorer, in order to compare and see if all file-types icons are present...

• Please, tell us what version(s) of TC you are using, what OS, and the main infos about the PC, network (if existing) etc.
Glad to hear more,
  Kind regards,
Claude

I have A PIII, 1000Mhz, 384MB RAM, WinXP with all Updates and TC6.01. I have the same problem. I already had it with TC6.00 on Win2000, it was just the same.
I don't think that my antivirus program is the problem (F-Prot). I don't wanna test it, because i had to disable it for a very long time then, to be sure that it doesn't happen anymore.

And I have a different AV program (Norton AntiVirus), so it's not that. My PC is an AMD Athlon XP 2100+, 512MB of RAM running XP Home, no network & TC v6.02 (but it happened on previous versions as I said). When the icons in TC are changed, the icons for the same file extensions in Windows Explorer are fine - they show the icons they are meant to, indicating that it is a TC problem.

• Well, we have to wait and see whether other users had the same issue.
• An idea : have you many plugins for TC / Lister installed ? If you have, please try to disable them one by one, maybe the problem should disappear...
• I don't think that TC itself be faulty, since I never see that, and don't hear anything like this...

TC loses the icon for a filetype every time it is opened on my PC

Maybe this is related to the windows icon cache, which is pretty small by default.

Try to increase the value (default: 512) at :

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Max Cached Icons

[romulous]

2 sqa_wizard: Wouldn't this mean that Windows Explorer is affected by the problem too? It's not on my PC - only TC has the problem.

[romulous]

2Clo:
-At least one has (see post above)
-no plugins for TC itself, 2 for Lister...but wouldn't Lister plugins only affect TC like this if Lister was running all the time?

As ghisler described in http://www.ghisler.ch/board/viewtopic.php?t=2908 Total Commander uses it's own icon caching mechanism.

In http://www.ghisler.ch/board/viewtopic.php?t=3420 ghisler provides a workaround. Files/Associate/OK rebuilds the TC icon cache.

[romulous]

Well, that explains why the problem only affects TC. The "Files-Associate With" workaround is what I've been using, but it quickly gets annoying doing this everytime you open TC (filetype icons disappear everytime TC opens on my PC) - a fix for the problem itself would be better. I wonder if it is listed in Christian's "list of bugs to be fixed"? Maybe something as simple as TC dropping its own cache & using the Windows one?

Well, AFAIK no - it looks like Christian just refused to do something with this problem. Actually it's well-known, I have reported about it rather long time ago.

Thanks for the info Black Dog. Looks as though we will just have to put up with it for the time being & hope that it does make it onto the list sometime in the future...

Sometimes, I also have the file type association icon problem, and in Chinese forum I've seen some ppl reported this problem too.

So, Yes! we really need it.

I've had this occur a couple of times, but its very rare for me. I usually just restart Total Commander, since I notice it seconds after I open it.
Because until now, it's only affected filetypes in the startup directories (the last used directories from last session).

[Gingo]

I too have had this problem for quite some time, a couple of years at least I think. For me, just restarting TC usually fixes it.
