c#编的，比较简单的小工具，批量过滤文件-Batch filter paper

這支小程式可以瀏覽列出目錄裡的檔案、過濾副檔名、單筆執行、批次執行..還算可以學到東西的一支小程式-This little program you can browse the file directory list to filter extension, single execution batch execution .. still can learn something of a small program

批量替换字符串，批量上传缩略图，根据后缀名过滤文件等(Batch replacement string, batch upload thumbnails, filter files based on the suffix name.)
