Find all files that are NOT of a specific type/extension in folder?

Question

Windows 7 Ultimate 64bit:

I'm looking for a way to find all the files in a directory that are NOT of a specific file type or extension.

Example: I'd like to find every file that isn't an .mp3 in my music folder (and all sub folders).

Answer 1

type this in the search box of the directory you want to search

NOT *.mp3

Answer 2

From a command prompt you can pipe the direcotry list into findstr, and use findstr's V switch to exclude lines like the filter (in this case, lines ending in .mp3), as well as the I switch to make the find procedure case-insensitive.

dir | findstr /vi "*.mp3"

Answer 3

I just open the folder with Windows Explorer, add the Type column to the display, and sort on it.

Answer 4

Step 1: Get FindUtils.
Step 2: find some\dir -type f ! -name *.mp3

Answer 5

You could try

xcopy /L /EXCLUDE:.mp3 /S DIRNAME .

The /L flag forces xcopy to only list but not copy the /s runs through all subfolders and the exclude misses out mp3s

Answer 6

For a quick look I sort by clicking on the type column header in Explorer. There is a pull down option to tick boxes for only the files you want listed.

Answer 7

You can check a mime-type with:

file -i <YourFile> -F "::" | sed 's/.*:: //' | sed 's/;.*//'

and then write a script.
