1. When uploading a file to the FTP server via the FTP protocol, the file path is: 455ba786a7e62dd5cf24f3d6bb32c26c\source\ftp\2021\9\16\b9cf2265-736a-4df8-b02b-215b91ad4e3e.mp4. However, the actual path on the FTP server is: \source\ftp\2021\9\16\b9cf2265-736a-4df8-b02b-215b91ad4e3e.mp4. The missing part of the path is: 455ba786a7e62dd5cf24f3d6bb32c26c. See Figure 1.

2. In the FTP client software FlashFXP, creating a new directory named 11 in the root directory fails with the error: MKD 11 550 Create directory operation failed. See Figure 2.

3. Creating a new directory named 11 under the directory \source succeeds: MKD /source/11 257 “/source/11” created. See Figure 3.

4. Readjust the permissions of the FTP account. Grant the root directory / the highest permission of 777. It turns out that previously only the directory /source had 777 permissions.
5. Upload a file to the FTP server via the FTP protocol with the file path: 455ba786a7e62dd5cf24f3d6bb32c26c\source\ftp\2021\9\16\1ec9def7-3c74-4c3a-8cb2-c146d5380531.mp4. It now actually exists on the FTP server as expected. See Figure 4.
