Been awhile and this is from memory, so I may be misremembering... but I /think/ the CSIDL for APPDATA started with Win98SE (maybe 98 mach I, but for some reason my brain's saying SE), and prior versions of Winders don't have a CSIDL for APPDATA. And IIRC, the API should return nothing if the CSIDL (in this case, APPDATA) doesn't exist (spits an error, thus returning nothing). So you may only need to check if the API returns something for the CSIDL, if it doesn't then it's either Windows Old or Windows Hosed. It's been awhile since I've looked at my special folders functions, and I'm not on my dev box at the moment, so the odds I'm remembering correctly are probably around 50/50 <g>

For curiosity sake, I just fired up a Win95 (950b; build 1111) VM that's *almost* pure. The API returns these folders: CSIDL_APPDATA: C:\WINDOWS\Application Data CSIDL_LOCAL_APPDATA: C:\WINDOWS\Local Settings\Application Data CSIDL_COMMON_APPDATA: C:\WINDOWS\All Users\Application Data Which all show a creation date just 17 minutes past the \Windows\System folder. Unfortunately, the system isn't totally pure, as I did install a few utilities (textpad, winzip) before saving it. And it does have IE3 on it (can't recall what came with this one?). But it sorta shows that these folders will virtually *never* fail to be there, eh? Do you recall any of the specifics behind your test? -- ..NET: It's About Trust! http://vfred.mvps.org

In some versions of Windows the folders aren't created automatically, so you have to use CSIDL_FLAG_CREATE(In shell32.dll version 5.00 or above).

Did you mean shell32.dll version below 5.00? What I understood so far is that with shell32.dll version 5.00 or above the folder will exist for sure. Am I wrong? And seemingly, reading Karl's latest post in this thread, it existed in Win95. |
