Specifically, the data files are uploaded to a cloud, the cloud acquires information of the data files, and the cloud generates identification codes for each data file by using a CRC32 and MD5 algorithm, wherein the identification codes are a group of character strings.
The CRC32 algorithm appends an r-bit binary check code (sequence) to a p-bit binary data sequence, thereby forming a binary sequence of total length n + p bits; the MD5 algorithm generates a 128-bit (16-byte) hash value; the CRC32 algorithm produces a binary sequence of total length n and the MD5 algorithm produces a hash value that in combination forms an identification code. For example, after the data file is uploaded to the cloud, the cloud generates a binary sequence with the total length of n as a by using a CRC32 algorithm, generates a hash value as B by using an MD5 algorithm, and generates an identification code as AB or BA. The CRC32 algorithm can detect the correctness of data, and the MD5 algorithm obtains different hash values on different uploaded files and has uniqueness, so that the identification codes correspond to the uploaded data files one by one.
After the cloud generates the identification code, the identification code is stored on the cloud end, and meanwhile the identification code is sent to the USB flash disk, and the USB flash disk receives and stores the identification code.

S43: and if so, canceling the uploading of the data file, and receiving and storing the identification code corresponding to the data file.
S44: if not, continuing to upload the data file.
Specifically, after the user selects a cloud mode, the USB flash disk sends an uploading request to the cloud, after the cloud receives the request, the cloud identifies the data file, a discrete value of the uploaded data file is obtained through an MD5 algorithm, the discrete value is compared with a discrete value in a storage identification code in the cloud, if the discrete value is the same as the discrete value, the data file is already stored in the cloud, the data file is not uploaded, and the identification code of the data file is sent to the USB flash disk by the cloud; if the data file is not stored in the cloud, the USB flash disk continuously uploads the data file to the cloud.
Alternatively, referring to fig. 4, the step S5 includes the following steps:
s51: the file name of the uploaded data file is identified.
S52: and generating a corresponding folder according to the file name, and storing the identification code in the corresponding folder.
Specifically, when the data file is uploaded by the U disk, the U disk receives the identification code of the data file and stores the identification code into the corresponding folder by identifying the file name of the data file and generating the corresponding folder on the U disk according to the file name. For example, the U disk uploads a video named "company time" to the cloud, a folder of the "company time" is generated in the U disk, the identification code corresponding to the video is C, and the U disk receives the C and stores the C in the folder of the "company time".
Optionally, step S52 includes the following steps:
