A NOMEDIA file informs apps to not scan a folder for media files. This prevents delays when viewing gallery and multimedia. Android periodically searches storage to locate media files.
A NOMEDIA file has no filename prefix or data. It just signals no media in that folder. Deleting it makes apps rescan that folder. Some Android apps use NOMEDIA to hide their own media files from apps.
You can delete a NOMEDIA file if you want apps to scan that folder again. To hide a folder, create a blank text file named .nomedia inside it. Multimedia programs will then skip scanning that folder.
NOMEDIA files don’t contain data. Folders with them hide media from apps. You can freely create and delete them to hide or show content. They prevent apps displaying media files.
When searching, media scanners check for NOMEDIA files. If found, that directory’s media isn’t shown in the gallery. So apps hide their media by creating NOMEDIA files.
To open NOMEDIA files, first check the resources to run .nomedia Manager. Also check if the file was fully copied, otherwise try downloading it again. If still unable to open, contact IT support.
