Bug 467914

Created attachment 157679 [details]
Three photos each of two image files (a PNG on the left and a JPEG on the right) being labeled in different ways, put together into a collage.

SUMMARY
Every single file type is labeled in File Explorer as just "Image File" if the user has set Krita to open files with their extensions onto by default.

For example, if you have Windows set to open both .png and .jpg files in Krita, the "Type" section in relevant viewports (like the Details view, as well as the Details pane in the right sidebar if that's turned on) simply labels each file as just "Image File". This, despite the file types having multiple well-known differences in how image data is stored.

Other apps don't give each file type a name, so the Windows File Explorer default is just "$EXTENSION File", like "PNG File" or "JPG File". (See attachments 5 and 6 for the Windows 10|11 built-in Photos app.)

Certain programs, like LibreOffice Draw, go out of their way to provide more detailed descriptions of a file's type, like labeling a .png as "Portable Network Graphics". (See attachments 3 and 4).

STEPS TO REPRODUCE
1. Open File Explorer.
2. Go to a folder with both a .png file and a .jpg file on them.
3. Make sure Windows is set to open Krita for both file types by default. (To be sure, right-click, then "Open with >", then "Choose another app", then select "Krita", then "Always" button.)
4. In File Explorer's top bar, click the "View" dropdown, select "Details". (Alternatively or additionally, "View" then "Show >" then check "Details pane".)

OBSERVED RESULT
See both of them labeled under "Type" column as "Image File", with no distinction between PNGs and JPEGs. (See attachments 1 and 2.)

EXPECTED RESULT
See the .png file labeled as "PNG File", or much better, "Portable Network Graphics File". Then see the .jpg file labeled as "JPG File" or "Joint Photographic Experts Group File".
