- Look for a “Delete” option (usually represented by a trash can icon).
- Confirm the deletion. Be cautious, as deleted files are often permanently removed (though some file managers offer a “recycle bin” or similar feature).

Creating Folders and Subfolders to Categorize PDF Documents

Hierarchical organization is a powerful technique for managing large collections of files. Creating folders and subfolders allows you to categorize PDFs logically, making it easier to locate specific documents. This method is particularly useful if you work with various types of PDFs, such as work-related documents, personal files, and e-books.

Here’s how to create folders and subfolders:

Open your File Manager: Access the file manager app on your Android device.
Navigate to Your PDF Storage Location: Go to the location where you want to create the folder (e.g., Internal storage or SD card).
Create a New Folder:
- Look for an option like “New folder,” “+ Folder,” or a similar icon.
- Tap on it.
- Enter a name for the folder (e.g., “Work Documents,” “E-books,” “Recipes”).
- Confirm the creation.
Create Subfolders (Optional):
- Open the main folder you just created.
- Repeat the steps for creating a new folder to create subfolders within the main folder (e.g., “Project A,” “Project B” within “Work Documents”).
Move PDFs into Folders: Select the PDFs and use the “Move” or “Cut” option to place them into the appropriate folders and subfolders.
