一个朋友在COPY文件时,提示错误信息"无法复制 filename: MS-DOS功能无效"
具体信息如下:
OS: Windows
View: dynamic view
process: copy a directory recursive from Z(MVFS) to D.

我第一反应就是权限有误. 建议用fix_prot试试.
还有一种可能是 text mode 问题.

不知哪位大虾遇到过类似情况, 请指点指点
如没遇到,嘿嘿,也请像我一样, 想想会因哪些问题引起的.

欢迎一起讨论!

这个错误倒是没有遇到过。不过见过类似的。

曾经从vss->cc,有一个项目的目录名字叫做， PRN

so.........

是直接copy还是ccopy？？？

是否是磁盘问题哪

他是做的直接COPY.

我觉得权限出问题的可能性比较大
建议用fix_prot 试试

直接copy跟权限没什么关系吧

估计是source pool甚至硬盘损坏了

这种提示一般都是硬件原因，和CC没什么关系

压缩一下再考出来。试试
