errors with ImDisk ramdisk(drive)

[ElnathK]

I'm using windows 10 and imdisk toolkit to mount the ramdisk on R. it is no problem that starting fman and browsing the root of R drive. it shows root of R drive and I can open files in the root on fman. (below are errors. of course, it doesn't occur on internal, external drive (USB 3.0 HDD) and mounted CD/DVD ISO image on windows 10)

1. fman cannot access subfolder of R drive.

2. if I closed fman that any pane viewed R drive, (next time) fman have started with Traceback message(pane directory also reset to user directory).

3. If I rename the file on the root, it works. However, a traceback message appears.

I'm having the same issue, although the error occurs when I try to access the root of a normal NTFS volume in a normal HDD drive.

Windows 10.0.16299.125.

Command 'OpenDirectory' raised error.

OK, so I found the possible cause (for my case): in my system there is a file that does not have a (valid) modification date, so fman throws this exception and breaks the operation: Removing the problematic file solved this situation.

I fixed @felubra's bug (though I don't know why it occurred). Will go live with version 0.8.5. But I believe it's unrelated to yours @M53. I will have to take another look.
