After playing around with the code of your published example ESP32_FTPClient/examples/download_file/download_file.ino I can tell you now that by simply deleting, removing or commenting list[i].toLowerCase(); at line 77 of your code will solve the problem. Then the complete sketch will works as you intended. This is the case when using the FTP server of 000webhost.com.
Using the FTP server of my own ISP then I have to add ftp.CloseFile() before a next ftp.InitFile() is sent to let the sketch working correctly (same experience as with your ESP32_FTPClient/examples/upload_image/upload_image.ino. See issue #30).

.Sorry for using the three Serial monitor output text as a link. Maybe there is another way, which I did not find.

If you believe there is an issue with the library, please share the code you used, the output of the terminal and the detailed steps on how to reproduce it.

If I haven't written the issue in enough detail I apologize.
I do not know where the issue is, but if you like to download myPhoto.png into a new map myNewDir, then that does not succeed with your example file ESP32_FTPClient/examples/download_file/download_file.ino
And according this sketch it is supposed that there must already exist a file myPhoto.png in the working directory on the server.
Below is described what I have done.
I downloaded your file ESP32_FTPClient/examples/download_file/download_file.ino.
I changed in that file the credentials at line 16...21
I changed the path on line 47 and 109 of your working directory into my working directory (public_html/xxx) at 000webhost.com .
I changed line 23 of the sketch into ESP32_FTPClient ftp (ftp_server,ftp_user,ftp_pass, 5000,2); to have Verbose=2.
Then the sketch is:

The File Manager of 000webhost.com showed now in my working directory /public_html/xxx :

With a picture program I created a pic and saved that as myPhoto.png and uploaded that file to my working directory.
I deleted helloworld.txt to avoid a message that helloworld.txt does already exist with the next run.

The File Manager of 000webhost.com now showed in my working directory /public_html/xxx :
- helloworld.txt
- myPhoto.png (remark: the Contentlist shows myphoto.png, see the Serial Monitor output at 14:04:52.662)
I deleted helloworld.txt to avoid a message that helloworld.txt does exist with the next run.
Now in the sketch at line 62 I changed the filename myPhoto.png into myphoto.png and saved the sketch.

The File Manager of 000webhost.com shows in my working directory /public_html/xxx :

I deleted helloworld.txt to avoid a message that helloworld.txt does exist with the next run.
Now I changed the filename myPhoto.png into myphoto.png in my working directory /public_html/xxx

The File Manager of 000webhost.com now showed in my working directory /public_html/xxx :
- myNewDir
- helloworld.txt
- myphoto.png
The File Manager of 000webhost.com showed in my working directory /public_html/xxx/myNewDir :
- myphoto.png
So only when in the sketch (at line 62) the filename is written as myphoto.png and in the working directory /public_html/xxx
the file myphoto.png is found then the sketch is generating the myNewDir map and is copying the file myphoto.png in it.
To make sure I tested this sketch also with an ESP32 Dev module. Same result.

And what is the problem? on the first example you shared it prints 13:54:18.415 -> File size is: 0 therefore it is clear that the size is invalid and thus no file to download.

The problem is that I experience that the filename to be downloaded with this sketch must have a lowercase name.
You are right, I agree, at that moment there was no myPhoto.png yet in my working directory.
After that moment I had created a .png file with that name you specified in the sketch as myPhoto.png and I have saved that file into my working directory.
File size 3.0 kB
Running the sketch again, then there should be still no file (or invalid) in my working directory dat the Serial Monitor shows at 14:04:52.662 -> File size is: 0.
However, I have showed you there exists a file with the name myPhoto.png of 3.0 kB in my working directory.
The run of 14:08:27 is only meant as an intermediate step to check what the result was when the file name in the sketch at line 62 is changed into myphoto.png and myPhoto.png in my working directory hasn't yet changed into myphoto.png.
The result of that step is 14:08:27.617 -> File size is: 3052 but the sketch can't open file myphoto.png.
Only when the specified filename in the sketch at line 62 consists of only a lowercase name (I changed it into myphoto.png) and there exists a file in my working directory with the same lowercase name (I changed that as well into myphoto.png ), only then the sketch generates the myNewDir subdirectory in my working directory and downloads that file in there (the run of 14:11:22.750), as the File Manager of 000webhost.com showed me.

Aaa ok, but that is just a name mismatch that you can fix on your code. I don’t believe there is an issue with the library, so I’ll close this issue.
