Have you ever opened a Microsoft Office document such as word, excel, or presentations? These documents usually have extensions such as .doc,.docx, .xls, .xlsx,.ppt, and .pptx. While opening these documents you may have noticed another file with the same document name in the same directory. The only difference is that the filename starts with a tilde (~) followed by a dollar sign ($). If yes, then let's check out what this file is all about.
The file starting with a tilde (~) followed by a dollar sign ($) with the same document as yours is known as Owner File( also known as a lock file). It is a kind of temporary file that holds information about the current user who is editing or using the file. This owner file is usually hidden. To view these kinds of files first we need to unhide them using window explorer.

What is a Temporary File (~$ File)?
A temporary file is created to hold information while the file is being created or changed. Temporary files act as a safety net to prevent data loss when a program performs certain functions.
Is there only one kind of temporary file? The answer is No.
There are many kinds of temporary files available in windows. Some examples of temporary files are MS-DOS-based files, Document-File-Based Files, Transacted Document Files, Specific word-based files, and many more. Owner file falls under the category of Specific word-based files.
Word decides where and when to create and delete temporary files automatically. The temporary files are only present for the duration of the current Word session. All temporary files are first closed and then erased when Word is properly closed.
In my situation, I discovered this type of $ file while opening, creating, or updating an office file such as a documents file, an excel file, or a powerpoint file.
Importance of ~$ file
You might be wondering, “Is there any use in creating such temporary files?”. Well, Let's see get into more detail about it.
If a document is shared across the computer network and is simultaneously needed to be accessed by two users. The owner files to prevent multiple users from attempting to change a document at the same time. If another user wants to edit it, s/he should create another copy of the same file and do their tasks.
Can I delete the owner file (~$ file)?
You might also be wondering as the temporary files only occupy memory and are of not much use. Can we delete such owner files? The answer is yes you can but you won't need to do such a task. First of all, these owner files are only of usually 1KB. Secondly, they will be deleted automatically after the word document is closed.
You can safely remove a $ file without worrying about losing any of your data. However, information loss may occur if the program or system crashes and the $ file is unavailable. Also, note that Users cannot prevent the creation of ~$ files.
Where is $file ?
~$ files are typically located in the same directory as the original file.
Can We delete the owner file while the document is opened?
No, you cannot delete the owner file while the document is opened. The owner file will be locked by the system.
Also once this file is deleted then it cannot be recovered.
Complications with the owner file (~$ file)
Imagine a scenario, while working in our office on a hectic day with documents. Your window crashes. Hope that does not happen. In this case, the word document cannot automatically delete the owner file present in the folder where your document was present. Then the next moment when the crash was fixed. When you open your PC again and try to open the same file you might get an error message as follows:
“The document is locked for editing by another user. To open a read-only copy of this document, click…”
