3 ' 5) return end.
The user can also can arrange according to existing screening conditions according to the increase in demand screening conditions of self when in use, for example, only use the file frequency of utilization this as screening conditions, so, above-mentioned disk automatically cleaning flow process as Fig. 3 b.1 shown in:
3 ' 11) one first file frequency of utilization threshold value is set;
3 ' 12) judge cleaning finish after when the usage space of front disk whether less than cleaning threshold, if, carry out next step, if not, carry out 3 ' 14);
3 ' 13) setting one is lower than the second frequency of utilization threshold value of the above-mentioned first frequency of utilization threshold value, returns execution in step 3 ' 12);
3 ' 14) All Files less than described threshold value is satisfied in cleaning;
3 ' 15) setting one is higher than the 3rd frequency of utilization threshold value of the above-mentioned first frequency of utilization threshold value;
3 ' 16) whether work as the usage space of front disk less than cleaning threshold after the judgement cleaning is finished, if, return end, if not, after continuing the satisfied All Files of cleaning less than described the 3rd frequency of utilization threshold value, setting one is higher than the 4th frequency of utilization threshold value of the 3rd frequency of utilization threshold value, repeats to till the front disk usage space is less than cleaning threshold.
The threshold value here can be to be set up on their own or done default setting by producer when appearing on the scene by the user, and for example, producer can be provided with one group of threshold value that the amplitude with every grade of fixed percentage increases progressively, and selects use from low to high for the user.Can in the scope of conditions permit, delete minimum user data like this.
If the user selects multiple screening conditions to carry out Disk Cleanup, for example, the user selects according to the file frequency of utilization, and three conditions of the priority of file type and file size are carried out the disk space cleaning successively, above-mentioned disk space clean-up process then as Fig. 3 b.2 shown in:
3 ' 21) one first file frequency threshold is set;
3 ' 22) whether usage space was less than cleaning threshold, if carry out 3 ' 34 after above-mentioned file was cleared up in judgement), if not, next step then carried out;
3 ' 23) All Files less than this first threshold is satisfied in cleaning, ' 22 of returning step 3);
3 ' 24) further screen, one first File Privilege threshold value is set according to File Privilege;
3 ' 25) judge the above-mentioned file of cleaning after usage space whether less than cleaning threshold, if, execution in step 3 ' 27), if not, then carry out next step;
3 ' 26) All Files less than this first File Privilege threshold value is satisfied in cleaning, ' 25 of returning step 3);
