SevenZip.pas BUG修改版
本来用的是Henri Gourvest <hgourvest@gmail.com> 1.2版本
然后发现了2个问题:
1.对于文件名中带有空格的文件, 无法压缩, 原因是1488行, 压缩调用的是TStringList.Delimiter 来拆分文件字符串, 而空格是默认分行符, 导致文件名错误
2.解压缩函数, 如果目标文件已存在并且为只读属性时, 报错, 原因是1105行 创建文件流的时候直接使用了TFileStream.Create(path, fmCreate)导致
针对以上2个问题, 对该PAS文件进行了修改, BUG解决:
另外, 增加了一个WorkPath变量, 用于指定7z.dll文件的绝对路径
