MTP Device Folder Segmentation for File Transfer Speed
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As the number of media files stored in an MTP device increases, the speed of reading and writing files decreases, causing user inconvenience due to the conventional method of storing files in a single folder without effective management, leading to slower file transmission.
Innovation Solution
A method and apparatus for controlling an MTP device to generate a second folder when the number of files in a first folder reaches a predetermined threshold, storing media files in the second folder and registering the first folder as the parent object in the device's database, thereby managing media files effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If media files are stored in a single folder in an MTP device, then the file management structure is simple, but the reading and writing speed decreases as the number of files increases
Solution Approach 1:
The patent applies segmentation by dividing a single large folder into multiple subfolders when the number of files reaches a predetermined threshold. This segmentation reduces the number of files in each folder, thereby improving file reading and writing speed while maintaining manageable organization structure.
2Ease of operation
If media files are stored in a single folder, then the file organization is simple, but the file transmission speed from MTP host to MTP device decreases
Solution Approach 1:
The system automatically segments files into multiple folders based on file count thresholds, which improves file transmission speed by reducing the overhead of managing large numbers of files in a single folder, while keeping the organization simple through automated management.
Solution Approach 2:
The MTP device performs self-service by automatically creating subfolders and distributing files when thresholds are reached, eliminating the need for user intervention in folder management while maintaining simple operation for users.
3Quantity of substance
If the number of files in a folder increases, then more files can be stored without creating additional folders, but the delays in reading and writing files increase
Solution Approach 1:
The patent implements automatic segmentation into subfolders when the file count in a parent folder reaches a predetermined threshold, thereby limiting the number of files in any single folder and reducing reading and writing delays while maintaining the ability to store large quantities of files across multiple folders.

AI summary
A method and apparatus controls an MTP device to manage a media file transmitted by an MTP host. According to the method, when the number of files in a folder assigned by the MTP host is equal to or more than a predetermined number while storing a media file received from the MTP host, the MTP device generates a new folder and stores the corresponding media file in the new folder. Accordingly, the files within the predetermined number can be stored in one file. Since the number of files stored in one folder is limited, delay in processing media files due to the large number of files can be reduced.
