The invention discloses electronic equipment, and a file partitioning method applied to the same. The method is applied to the electronic equipment, and comprises the following steps of receiving a file modification operation; obtaining a file partitioning range corresponding to the file modification operation according to the file modification operation and a first partitioning result; obtaining a first file partitioning instruction; carrying out a first partitioning operation on data in the file partitioning range according to the first file partitioning instruction to generate a second partitioning result; when obtaining a file synchronization instruction, transmitting the changed file block according to the second partitioning result. By utilizing a partitioning history result, after a file is modified, the file partitioning range corresponding to the file modification operation can be obtained, and only the data in the file portioning range is re-partitioned, so that the file partitioning time is shortened, the file partitioning efficiency is improved, and the amount of data transmitted when the file is synchronized is reduced.
