Find Files will help you to find any files easily. A first search by name can help you to create a scope which you will be able to reduce by date.
By these two steps you will be able to get quickly last pictures or a specific song. System and external files as any files on your device could be searched. The only permission needed is to access storage. Nothing is saved or send by any transactions.

Once the file or folder is found you will have several options such as open it read it...

You can search file like photo video pdf…

For example if you search photos from a birthday you can write jpg in the search file input. Once you have the files list you can select the date of this day.
If you know the filename you can directly search the file by a part of the name.

As the connection is request only if you want to give me some supports by rating or donation the search is offline. Find Files do not need any connection.

I will improve the application by taking comments into account.
