PC don't see all files / directories of Max2

Hello,

After having connected my Max2 on the PC through USB, I don't see all files or sub-directories in my file Explorer on the PC. It's always the same files or directories that are missing.

For example, into one directory, I have some hundreds of sub-directories on Max2 and can see only 7 on the PC.
In other directory, some files are "missing" on the PC while I can see them on the Max2.
When I try to copy a "missing" file (that I can see on the Max2 and that I have somewhere on the PC) from the PC to the Max2, I get an error, of course.

I tried all what I can (Rescan on Max2, unconnect - reconnect, ...) and the only thing that allowed to see the files or directory on the PC is to modify its name on the Max2 : then it appears on the PC. But I have some hundreds to checks !

Any ideas ?
