I have a dotnet 4.5.2 application, which is just a console application that saves some datafeed into a .txt file. The program depends on some .dll files (private data-connectors, I don't have control over them).
I installed dotnet 4.5.2 via winetricks
winetricks -q dotnet45 corefonts
Now I'm running my application
wine ~/datafeed.exe
and cannot filgure out there it actually saves my .txt files?
Wine's files are stored in /home/user/.wine/drive_c/ by default.
.wine is a hidden folder, so press Ctrl + H in your home folder to show it.
You can select other folders in most programs by browsing to the correct place on your hard drive.
The existing answer in incomplete.
Applications running in wine can store data in the locations specified in ~/.wine/dosdevices.
Those can also be specified graphically. To do so, launch Configure Wine from the dash and switch to the tab Drives. The rest should-be self-explanatory.
By default, there are 2 "drives" (as Windows calls them): c: and z:. c: by default points to ../drive_c which at that location is equal to ~/.wine/drive_c. So if the application running in wine stored its data on drive c:, it's in there.
However, drive z: points to / which is your file system root. This means that by default wine applications can access all files on your system provided wine has the permissions to do so. So (by default) your user permissions.
Anyways, it's likely that the application stored its data on drive c: and therefore in ~/.wine/drive_c but I think the above is worth knowing, especially if you don't find the file you're looking for in ~/.wine/drive_c.
Do this command in your terminal:
winefile
It will open a files manager in a window. Click "C:" to see the Windows directory.
If you, like myself, installed an application that needed to install wine, then .wine would be found under the snap directory of the application common data.
For the example where I installed acrordrdc :
~/snap/acrordrdc/common/.wine
