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
.
