Hi,
I discovered that, when a new file is added by host system (Windows 10) in a mounted drive, this file does not appears in DosBox 0.74-2.
One need to mount a new drive with the same path to see the file.
This could be a small problem if there were un mount command.
Also the number of free bytes is wrong. On my d: drive there are 50.8 GB free and DosBox displays only 249 MB free.

Example :
1) I mount d: drive on d:\temp local path.
2) I copy image222.jpg into d:\temp local path using the Windows explorer.
3) I mount e: drive on same d:\temp local path.

Here is the result :

1Z:\>mount
2The currently mounted drives are:
3Drive  Type                                                       Label       
4--------------------------------------------------------------------------------
5C      local directory C:\Program Files (x86)\DOSBox-0.74-2\      C_DRIVE     
6D      local directory d:\temp\                                   D_DRIVE     
7E      local directory d:\temp\                                   E_DRIVE     
8Z      Internal Virtual Drive                                     DOSBOX      
9
10Z:\>dir d:\image222.*
11Directory of D:\.
12File d:\image222.* not found.
13
14Z:\>dir e:\image222.*
15Directory of E:\.
16IMAGE222 JPG            218,071 23-06-2019 19:49
17    1 File(s)           218,071 Bytes.
18    0 Dir(s)        262,111,744 Bytes free.

Thanks in advance.

Both of those are expected behaviour.
You're not meant to mess with directories from outside DOSBox while they're mounted, but you can press ctrl-F4 to force a rescan of files.
The free space is limited to workaround some buggy dos programs that can't handle large amounts.

If you add/delete files on the host you need to update the directory cache in DOSBox with Ctrl+F4

Hi,
Thanks for your quick responses.
Reading another post, I discovered the -t floppy option and discovered also that mounting drive as floppy (using -t floppy) does not need to refresh the directory cache.
