Project Execution Settings

Clipboard buffer size between processes
Allows you to set the buffer size between processes from 10 to 1000 MB. This setting defaults to 10 and generally does not need to be changed unless you are specifically recommended to do so when troubleshooting issues.
Do not interpret this setting as the "maximum size of a list or table" used in the template. It is unrelated.
FTP operation timeout (sec)
The amount of time the program will wait for an FTP operation to complete.
Number of HTTP request attempts
How many times the program will attempt to make an ❗→ HTTP request.
Use alternative HTTP request method
Sets the alternative HTTP request transmission method as default. This is applied globally for the entire program and all new projects.
ZennoPoster has two ways of working with HTTP requests—an external solution (the standard method, Chilkat library) and a built-in solution (the alternative method). If something doesn’t work as expected when using the standard method for HTTP requests, try switching to the alternative method. You can also do this via Project Settings.
Use HTTP Connection Pool
Enables optimized processing of HTTP requests, increasing stability.
Maximum number of HTTP Connection Pool connections
Added in 7.3.0.0
This setting allows you to limit the number of connections for ZennoPoster and ProjectMaker, which helps stabilize the program when processing large numbers of HTTP requests.
Consider group order when using classic element search
When enabled, conditions will be checked in order, following the numbering in the "Group" column.

Save files safely
Helps prevent corruption of lists and files during unexpected server reboots.
Search for project with .zp extension when using "Project in project" action
Added in 7.4.0.0
When this setting is enabled, if the "❗→ Project in project" action uses an old-format project with the .xmlz extension and it is not found, the program will look for a project with the same name but with the new .zp extension.
Leave an empty UTF-8 encoded file
If a list remains empty during template execution, it will be saved with UTF-8 encoding.
Launch unfinished projects on startup
When the program starts, any projects that were left unfinished during the previous session will be resumed, provided you chose this option when closing the program.
Priority threads interrupt lower priority thread requests
Allows thread priority to be considered when processing requests in multithreaded template execution.
