Suggested January 2024 Ftp 550 Error: Permission Denied – Failed To Open File
If you’ve ever used the File Transfer Protocol (FTP) to upload, download or manage files on a server, you might have encountered an FTP 550 error. This error can manifest itself in several ways, with messages like “Permission denied”, “Failed to open file”, or “Failed to change directory”. These error messages can be perplexing and disrupt your work, particularly if you’re unsure about what they mean or how to resolve them.
In this article, we will explain what this error means, what are the common reasons that cause the error, and give you some ideas on how to sort it out. By the end of this article, you should have a clear understanding of the FTP 550 error and how to handle it.
When the FTP 550 error occurs, it is usually due to issues with the permissions associated with the file or directory you’re trying to access. The “550” part of the error code is a reply code from the server that means “Requested action not taken”. The detailed error message will usually give you a bit more context about what is going wrong. The “Permission Denied” portion of the error usually means the user doesn’t have the necessary permissions to access or manipulate the requested file or directory.

There are several reasons why the FTP 550 error might occur:
The user account you’re using to access the FTP server may not have the necessary permissions to open or manipulate the requested file or directory. The system administrator sets these permissions. They might have configured the account to have read-only access or to only access certain directories.
If the file or directory you’re trying to access doesn’t exist, the server will be unable to fulfill your request, resulting in the FTP 550 error. This is often due to typos in the file path or the file/directory having been moved or deleted.
If the file or directory you’re trying to modify is in use by another process or user, the server may prevent further modifications to ensure data integrity. This prevention can trigger the FTP 550 error.

There are several solutions to resolve this issue. Below, we discuss three potential fixes in detail:
You can verify your user account’s permissions using the “CHMOD” (Change Mode) command. This command can alter the permissions of a file or directory, allowing different types of access (read, write, execute) to the user.
For example, suppose you’re using a Linux-based FTP server and you want to change the permissions on a file named “example.txt” to allow read, write, and execute access for the owner. You could do this with the command: chmod 700 example.txt.
Before making changes, ensure you understand the security implications. Modifying permissions inappropriately can expose your files to security vulnerabilities. Always consult your system administrator before making changes to file or directory permissions.
Ensure the file or directory you’re trying to access actually exists. A common method to check this is to use the “DIR” command. It will provide a list of files and directories within the current location. If the file or directory isn’t listed, you’ll need to provide a valid path or create the file or directory if necessary.

To put it simply, the FTP 550 error is like a locked door or a missing room in a house. This error can show up if you don’t have the right key (permission) to open a door (file or directory), or if the room (file or directory) you’re looking for doesn’t exist or is already busy.
The key lesson here is to make sure you always have the required permissions and ensure the file or directory you’re accessing does exist. That means you should know what you can and can’t do with your FTP account, and also keep track of where your files and directories are located. Also, if a file or directory is already in use (like a room being occupied), you may have to wait for it to be free before you can use it.

Not to be confused with FTTP (Fibre To The Premises), FTP stands for File Transfer Protocol. It is a classic protocol, first published as RFC 114 in 1971. Since the personal computer has been a thing, it’s been helpful. Or even necessary to be able to transfer files. In the modern world, we have multi-gigabyte USB thumb drives and multi-terabyte external hard drives. And cloud storage provides a range of storage capacities and feature sets for most use cases.
Before USB was standardized and some of the biggest cloud storage companies had even been founded, things were a bit different. In 1971 the floppy disk had just been invented, an invention that would quickly enable data transfer between devices. FTP allowed transfer over the network, though the internet wasn’t a thing yet.
FTP was so early that it didn’t even use TCP, as that hadn’t been standardized yet, either. Instead, it used NCP or the Network Control Protocol, the precursor to TCP/IP. This led to a particularly distinctive feature of FTP that has never been changed, the dual port system. NCP was a simple protocol.
So for bidirectional communication, it was essential to have two connections on two different ports, one to send and one to receive. Despite eventually being moved to use TCP/IP, which doesn’t have this requirement and can operate perfectly well with a single duplex port, the FTP standard was never updated and retains its pair of port numbers.Use of FTP
The two port numbers that FTP uses are 20 and 21. Port 21 is used for controlling and issuing commands, while port 20 is used to transmit the data. One of the core things that need to be arranged in a connection before transferring files is the use of active or passive mode. In active mode, the client requests a file. Then the server opens a data connection to the client. Both firewalls and NAT present a considerable problem because the incoming transmission from the FTP server is on a different port and so can’t be linked to the correct device easily.
To get around this issue, the passive mode can be used. In passive mode, when the user requests a file from the server, instead of directly attempting to connect to the client on a different port, the FTP server informs the client of the port to which it should connect and lets the client initiate the connection. This effectively solves the connection issue of active mode and offers no downside beyond a slight delay in the start of file transfers.
Technically, the server must agree with the client on sending data. However, only one mode is used. That’s image mode, also commonly referred to as binary mode. In image mode, each file is sent byte by byte. The alternative modes include translating the entire file into 8-bit ASCII, which is only suitable for text files.Authentication and Security
Being a particularly early protocol standard, you might not be surprised to hear that FTP isn’t particularly secure. FTP does offer username and password authentication. However, it doesn’t encrypt any communications, meaning that anyone in a MitM or Man in the Middle position can “listen” to the traffic “on the wire” and just read the username and password used to sign in.
FTP also offers an anonymous login feature, useful for open FTP servers, such as those used to provide software updates. In an anonymous login, the username anonymous is used. The server will then ask for an email address as a password, but any value is accepted. The lack of encryption also means that files are transmitted insecurely, so FTP isn’t ideal for use with sensitive documents.
Over time a range of extensions and alternatives have been proposed to add security to FTP. FTPS is the primary option. It extends FTP with an option to encrypt the authentication and file transfer process with TLS and is interoperable with standard FTP clients. SFTP, specifically SSH File Transfer Protocol, essentially offers the same functionality as FTP but over SSH, a secure communication protocol, which makes it incompatible with standard FTP clients and servers.Conclusion
FTP stands for File Transfer Protocol. It’s an early client-server protocol for uploading and downloading files to and from an FTP server. FTP offers no security by default. While a username and password can be used, they are transmitted in plaintext, leaving them vulnerable to network sniffing. More recent extensions to FTP add the option to connect over TLS for security.
Browsers used to include an FTP client so that you could browse FTP servers directly without needing a separate client. In 2023, however, Chrome and Firefox dropped support for FTP, limiting support to discrete FTP clients. In the modern world, cloud storage solutions – and to a lesser extent, fast and spacious USB storage – have essentially replaced the use case for FTP by offering improved convenience, security, and speed.

Checking security software on your computer for rules against certain services is always a good start when encountering connection issues.
For instance, if your firewall blocks traffic to and from specific apps, such as Steam, they might not work as intended.
In turn, you may encounter error messages such as the Steam access denied one. The same goes for antivirus/antimalware software that you installed on your PC.
If security software has decided that Steam or some of its services are bad for your PC and should be blocked, you may encounter connectivity issues.Can’t connect to Steam even though I have Internet?
Sometimes, problems with a network may be traced back to a piece of malfunctioning hardware, such as a router or a switch. Or by usage behaviors that were not expected. Such are spikes in the network’s available bandwidth and variations in the application’s setup.
However, the error that is being issued by Steam might also be the result of problems with their systems or security breaches that they have had.
We recommend that you take a look at our guide with 6 methods to fix Steam connection issues.What other Steam errors should I be aware of?

Most of you might have seen CRDOWNLOAD files while downloading video, music files, document files, etc. They are temp files created by Chrome when you download a file. In fact, they are created by all Chromium-based browsers.
When the browser starts downloading a file, it first tags .crdownload file extension to the filename and removes it once the download is completed. This article discusses how crdownload files are different from other files and how to open it on your browser.What is a CRDOWNLOAD file?
Crdownload file is a partial or incomplete file commonly known as Chrome partial download files. They are temporary files created during the download process, and they can be used as a regular file once the download is complete. In simple words, Chrome creates crdownload files during the download process and removes the attached crdownload file extension when the download is finished.
Crdownload means “Chromium download”. This file extension is specific to Chromium-based browsers like Google Chrome – and even Microsoft Edge Chromium now.
Related: Download is in progress says Chrome; But nothing is downloading.How to open CRDOWNLOAD files?
Crdownload files are partial download files and they are of no use until your browser finishes the downloading process. To fully use these files, you need to resume the download process and delete the ones that are useless.
To open a Crdownload file:
Launch your browser and go to the download page.
Locate the files that have paused downloading.
Resume the downloading process or start the fresh download again.
If all the files you download are paused and have the crdownload file extension, it could mean there is an issue with your Chrome.
In such a case, make sure that your internet connection is good and update your browser to the latest version.
You cannot see a crdownload while downloading a file in the browser. However, you can view them in the folder where you are saving the file. As mentioned earlier, crdownload files are incomplete files. If you see files with .crdownload extensions, it only means that Chrome is either still downloading the file or it suggests the download has been interrupted.
If the download has stopped, it is possible to use a part of the file by removing the crdownload extension from the file name.
For example, if there is an incomplete file named audiofile.mp3.crdownload, you can use a part of the sound file by removing .crdownload extension and renaming it as audiofile.mp3. You can now open and use the file in an mp3 player, although the download is still incomplete. Similarly, if you are downloading an AVI file, you can use a part of the sound file by removing .crdownload extension. You can then open and use the file to play video in a VLC player as long as your browser continues to download the file.
You can open and use crdownload files of audio and video only in the programs for which you are downloading. You cannot use documents, archives, images, etc in the crdownload extension. It is worth noting that you cannot convert a crdownload file to other formats like Avi, mp4, or pdf as they are incomplete files.

A JAR file is an archiving format that not only stores directories and source files and can also be run as executable files. Such Java ARchive files can contain Java class files that will run when the JAR is executed.
While Archiver tools like 7-Zip can extract content from JAR files, but doing that is pointless – we need to execute the files just as we run the EXE files.How to run a JAR file in Windows 11/10
Since Java or JAR files can’t run on Windows on their own, you need to install the Java Framework or what is popularly called Java. That said, Java files can be dependent on a particular version of Java. So the steps you need to take to open JAR files on Windows 11/10 are:
Download and install Java.
Set the System path
Run the JAVA file
Set Java file association
Establish a file association with Java runtime.1] Download and install Java Framework
To run a JAR file on Windows, you need to install Java on your system. Go to Java Download Page, and install it. The default will install the latest version only. However, if your JAR file needs a different version of Java, you can download it from here.
Sometimes, an existing older version of Java can cause an issue. So, if you are facing such a problem, make sure to remove the older version first. Use the official Java Remover tool to get rid of it. Then install the latest version.2] Set System Path for Java
Next, you need to set the JAVA_HOME path. It ensures that any JAVA file you run can find the necessary libraries for the program. You can also use the command line to echo the Java path to determine if it is correct.3] Run a Java or JAR file
If you have a JAR file which is not running on its own, then you can use java JDK to run it. Open Command Prompt, and type java -jar name_of_jar_file.jar. It will execute the JAR file automatically.4] Set the Java or JAR file association
The last step is to establish a file association with Java runtime. It will make sure that every time you run, you are not asked to select a program that can execute it.
Select ‘Choose another app.’
And then choose Select app from the computer.
You should see ‘Java(TM) Platform SE binary’ listed in this context menu but don’t select it.
Locate the file which can run the JAVA or JAR file which is available in the path we suggested above.
Make sure to check the box which says, “Always use this program.”
Once done, all future JAR files will automatically open with Java run time library. You should see the Java icon for all of these files.How run Java JAR from command line?
You’ll need to use the java command to run a .jar file
If you don’t have java installed, you can fix that by installing the default-jre package.
We hope these tips were easy to understand and were of help to open or run a Java file on Windows 11/10.
