When the disk space is tight, in addition to clear the garbage file, the large file on the disk is also a play, in fact, in the Win7 do not need other software, we can easily find large size files.
First locate the folder: If you want to search all disks, just press Win+e to open the Explorer directly, and if it is a specific disk, select the appropriate partition on the left; if the folder is also simple, you know.
Next, just enter the size in the search box: >300m "after carriage return (after the test half angle of the colon can be, the system is determined to be available, but must have), so will search out the specified location of all files larger than 300M, very convenient, for the following file size can use G, M, K and other units, if you want to more accurate byte number, you can enter specific numbers, such as "Size: >100000000" This is also possible.
If you want to search faster, you can index the specified partition, but you know that the index of Win7 has a "slight" problem, sometimes the index is not updated, there are some problems that should not occur mildly. So to pursue accurate results, or to turn off the index, after all, after the search results we can still save it, convenient to use again.
