Everything seems ok but for the columns in search mode, check screen
When I do a search filename column is shortened to 3 or 4 letters, settings in folder options are the same as for all the other options can please you tell me what I'm missing here ?
Looks like the filename column is set to only use/fill the remaining space, and the location column is set to auto-size and eating all the space.
Changing either column can fix things, depending on exactly what you want. I personally have location set to expand, so it goes off the side if the filename column needs more space.
Here is where to check the settings for the Search Results folders, and where to make the changes:
To learn about the column modes in depth, here's a video tutorial about them:
n.b. For Find Results (from the internal Find Files tool) as opposed to Search Results (from Windows Search), you'd normally need to edit the Collection format instead of the Search Results one.
Also check in the top of the list of formats, Path Formats section, for anything saved for a specific set of results, e.g. "col://Find Results" would override the Collection format if the results go to a collection called "Find Results". That would only be there if explicitly saved, however.
It worked but I had an issue here where if I opened search results format window through preferences\ folder formats\ search results any changes I made had no visible result but when I opened it by right clicking tab on search result window and selecting more after changing settings and clicking apply every thing changed accordingly.
Just letting know in case it happens to anyone else
