打开大源文件的MPLAB-X 3.60警告

我正在使用FATFS开源驱动程序进行SD卡操作。今天我想看看其中一个文件FFUMIDO.C，所以我在IDE源文件列表中双击它，而不是在IDE MPLAB-X的一个选项卡中显示文件，它显示了一个警告对话框，该文件声称文件太大而太大。在这样大的文件可能会使IDE无法访问！WTF是吗？MPLAB-X中的源文件大小有限制吗？该文件的大小为1.9兆字节，包含代码页之间的Unicode字符的翻译。这是配置所禁用的，因此该文件不包含活动代码，但我想知道为什么MPLAB-X声明它不能处理大的源文件……什么是实际文件？极限？？？？

    I am using the FatFs open source driver for my SD-card operations.
Today I wanted to look at one of the files, ffunicode.c, so I double-clicked it inside the IDE source file list.
Instead of showing the file in a tab in the IDE MPLAB-X showed a warning dialog claiming that the file was too big and that such big files could make the IDE inaccessible!
WTF is that?
Is there a limit to the size of source files in MPLAB-X?
The file in question is 1.9 Mbytes in size and contains the translations of Unicode characters between code pages.
This is disabled by the configuration defines so the file contains no active code but I am wondering why MPLAB-X is stating it cannot handle large source files...
What is the actual file limit???
