Thanks I have been able to reproduce but could not find out right now what is happening.

onexzero commented 1 year ago

Here is a fix! sys/create.c line 413 change fileObject->FileName, --> &fileObject->FileName
we need & operator.

Liryna commented 1 year ago

Very good catch @onexzero ! I applied the fix here https://github.com/dokan-dev/dokany/commit/938f012556d45d53f17adc446582b7964b2773e2 Thanks for not giving up on this issue 👍
