I am really grateful to you for the way you tried to explain me.
1.I had copied the folder containing 60 videos from my C Drive of HP Laptop to Internal Storage of my this android mobile One Plus Two.For this I copied by connecting Laptop and Mobile through USB cable.
2. These went to File manager->Internal Storage->Categories->Videos-> here I RENAMED the files individually, by selecting the file, tapping 3 vertical dots and selecting Re name icon.
3. As suggested by you , from Menue of videos, I tried to check Details ( the Path,) for one of the files.It shows /storage/emulated/0/Download/Gallery/Original folder on Laptop/Orignal Name of the File.
4.NOW When I clicked Original Path,the latest edited (Renamed )name,got erased and only original name remains.
5. How to create a new folder from File Manager? After creating the folder in which application it should be saved? My preexisting Folders on screen are only gallery and Photo. Is it necessary to have both the folders?
5. Instead of Bothering so much to you, I would like to delete entire copied Folder (of 60 Videos ) from mobile and would like to recopy and transfer to mobile.For this, I shall appreciate your guidance in this regard. will you please suggest me the Best and simple way to transfer this folder with original titles,where it should be saved in mobile Location Folder/Application ) so that it can take minimum space,easily accessible (Home screen Short Cut ) and possibility of addition and deletion of folder and unaffected by deletion from any other file/folder.
No doubt, I am asking too much but I am sure you will be able to help me out.
Thanks and Regards.
