MLSD command

[BBBits]

Hi , just gave the example a test run.
couldn't drag'n drop a file into chrome , so connected with winscp
upload was fine at about 380kb/s
when I refreshed the DIR in winscp it was empty.
reloaded the ftp in chrome and the file listed ok.
added some folders with winscp but they show up as files in winscp .
winscp doesn't show the folder name "New Folder" perhaps because of the white space ?
here is some of the console.

Hi Barry, as i know browser ftp client functionality dont support write on ftp by drag and drop function. Browsers ftp client is readonly.

[fa1ke5]

if you create folder in ftp cliet server create folder on sd too, you can see mkdir instruction in this code:
if( SD_MMC.mkdir( path )){
client.println( "257 "" + String(parameters) + "" created");
}
for stable work in wincsp try setup connection parameters "passive mode" e.t.c

[fa1ke5]

or try totalcomander ftp client....

Hi,
the problem is actually with the response format of the MLSD command.
perhaps you haven't experienced the problem because your clients only use the LIST command
the correct response was actually commented out so I changed it and all is ok now.
// data.println(fn);
data.println( "Type=dir;Size=" + fs + ";"+"modify=20000101000000;" +" " + fn);
} else {
// data.println( fs + " " + fn);
data.println( "Type=file;Size=" + fs + ";"+"modify=20000101160656;" +" " + fn);

Winscp now displays correct dir structure

Thanks BBBits for pointing this issue. Your solution worked for me on OLIMEX ESP32-PoE and SD card, using FileZilla FTP client Passive mode

Same problem here.
Now it's solved.
Thanks!
It was driving me crazy!

Winscp now displays correct dir structure ![winscp_MLSD_Correct](https://user-

I had to figure this out myself, i wish i had seen your comment before and saved few hours.
By the way it still shows as below and the very reason why FileZilla is not able to list the files and directory.

data.println(fn);
data.println( fs + " " + fn);

Who so ever is watching this comment, uncomment below lines

data.println( "Type=dir;Size=" + fs + ";"+"modify=20000101000000;" +" " + fn); 
data.println( "Type=file;Size=" + fs + ";"+"modify=20000101160656;" +" " + fn);**

At last, thankyou to everyone who made efforts to make and maintain this library.

Внес изменения в мастер ветку, теперь используются
data.println( "Type=dir;Size=" + fs + ";"+"modify=20000101000000;" +" " + fn);
data.println( "Type=file;Size=" + fs + ";"+"modify=20000101160656;" +" " + fn);**
Проблему закрываю, спасибо всем участникам за их помощь
