Where does Stata save temporary files?

When working with data in Stata, the software often needs to create temporary files to handle various processes and computations efficiently. These temporary files are stored in specific locations based on the operating system being used. In this article, we will explore where Stata saves these temporary files and how you can configure their storage locations.

Temporary files are created in Stata primarily for two purposes: handling large datasets and executing complex computations. Stata uses temporary files to store intermediate results to improve performance and save memory during data manipulations and statistical analyses. These files are generated and managed automatically by the software, and users do not need to intervene in their creation or deletion.

The default locations for saving temporary files in Stata differ based on the operating system:

1. Windows: By default, Stata saves temporary files in the Windows temp directory. This location is typically “C:\Users\[username]\AppData\Local\Temp\” or “C:\Windows\Temp\”. Stata creates a subdirectory within the temp directory with a name similar to “stata-tmp-XXXXXX”, where “XXXXXX” represents a random combination of characters.

2. macOS: In macOS, Stata saves temporary files in the user’s home directory under the following path: “/Users/[username]/.stata/temp/”. Stata creates a “.stata” directory within the user’s home directory if it does not already exist, and then creates a “temp” subdirectory within it to store the temporary files.

3. Linux: Similarly, in Linux systems, Stata saves temporary files in the user’s home directory under the path: “/home/[username]/.stata/temp/”. As with macOS, Stata creates the “.stata” directory if it does not exist and then creates the “temp” subdirectory.

It is worth noting that Stata automatically deletes these temporary files as soon as they are no longer needed. This ensures that the disk space is not unnecessarily occupied by unused temporary files, and it frees up system resources.

Can I change the location of Stata’s temporary files?

Yes, Stata allows users to change the default location of temporary files by modifying the value of the “TMPDIR” global system option. To change the temporary file location, open Stata and type “sysdir” in the command window. This will display the directories where Stata looks for system files. Among them, you will find the “TMPDIR” directory, which represents the current location for temporary files. To change it, you can use the “sysdir set” command followed by the desired directory path.

For example, if you want to change the temporary file location on Windows to “D:\MyTemp\”, you would type the following command:

“`stata
sysdir set TMPDIR “D:/MyTemp/”
“`

Similarly, on macOS or Linux, you would specify the desired path for the “TMPDIR”:

“`stata
sysdir set TMPDIR “/my/temp/location/”
“`

Make sure the specified directory exists before setting it as the new temporary file location. After changing the path, Stata will create the necessary subdirectories automatically. It is important to note that you need to set the new temporary file location every time you start Stata if you want to use the custom directory consistently.

Can I set a different temporary file location for each session?

Yes, Stata provides flexibility in setting temporary file locations for each session separately, allowing you to specify different paths based on your requirements. This can be useful if you have different storage devices or want to utilize faster storage options for temporary files.

To set a session-specific temporary file location, use the “set” command with the “temppath” option followed by the desired directory path.

For instance, if you want to set a specific location for the current session on Windows, you could use:

“`stata
set temppath “D:/MyTemp/”
“`

Similarly, in macOS or Linux:

“`stata
set temppath “/my/temp/location/”
“`

By using this approach, the specified temporary file location will only be valid for the current session. Stata will use the default location in subsequent sessions unless you specify a new location.

In summary, Stata saves temporary files in specific locations based on the operating system being used. By default, these files are stored in the Windows temp directory, the “.stata/temp/” directory in macOS, and the “.stata/temp/” directory in Linux. However, users can change the location of these temporary files by modifying the “TMPDIR” global system option. Additionally, Stata allows for setting a different temporary file location for each session separately, giving users flexibility to utilize specific directories as per their needs.

Remember that Stata automatically deletes temporary files as soon as they are no longer needed, ensuring efficient memory usage and freeing up disk space. So, you can rest assured that these temporary files will not clutter your storage in the long run.
