- Modifies `Loop, Files` to `Break` immediately after finding the first item, changing complexity from O(N) to O(1).
- Updates dependent UI message to be generic ("Dir is not empty") instead of specific count ("Dir has X items"), as the count is no longer calculated.

Pull request overview
Improves performance of the Citra Mod Manager by short-circuiting the “is destination directory empty?” check so it stops scanning after the first found item, reducing unnecessary filesystem iteration for large mod folders.
Changes:
- Updated
Loop, Filesdirectory scan toBreakafter the first match (non-empty detection). - Updated the user-facing message to reflect “non-empty” rather than reporting a full item count.
- Added a Python helper script used to apply the patch.

This looks like a one-off patching script (hardcoded target path, rewrites the file in-place) and isn’t referenced by the toolkit at runtime. If it’s not intended to be a maintained repo utility, consider removing it from the PR; otherwise, make it a proper tool (accept a path argument, avoid in-place writes or create a backup, and document its usage).

💡 What:
Optimized the directory emptiness check in
Other/Citra_mods/Citra_Mod_Manager.ahkby adding aBreakstatement inside theLoop, Filesloop. This stops the loop immediately after finding the first item, instead of iterating through all files and directories.🎯 Why:
The previous implementation iterated through every file and folder in the target directory just to determine if it was empty (
vCount> 0). This is an O(N) operation where N is the number of files. If the directory contains thousands of files (common for mod folders), this causes unnecessary I/O and CPU usage. The optimized version is O(1), returning as soon as existence is confirmed.📊 Measured Improvement:
Elseblock was updated from "Dir has X item(s)" to "Dir is not empty" to reflect that we no longer count the total items.PR created automatically by Jules for task 16332116086020472200 started by @Ven0m0
