But I can write or create file from other PC (Using same version of software, and using same way to mount) 

``` C:\Windows\system32>"C:\Program Files (x86)\WinFsp\bin\fsptool-x64.exe" perm Y:\ O:SYG:SYD:P(A;;0x1f01b9;;;SY)(A;;0x1200a9;;;SY)(A;;0x1200a9;;;WD) (perm=18:18:0555) C:\Windows\system32>"C:\Program Files (x86)\WinFsp\bin\fsptool-x64.exe" id 18 S-1-5-18(NT AUTHORITY\SYSTEM) (uid=18) ``` #27

希望能够回归，但是感觉概率不大

Try using type assertions

You should not use `errorx.CodeError` in your svc or biz layer. `errorx.CodeError` is design for api. I think that each layer of the program should handle and wrap errors individually,...

感觉这个因数设置为

Can't, it is difficult to reproduce the same situation.

Cool, it fixed now, thx. 👍
