Opening files for editing

To open a file for editing

The maximum size of files parsed by MPS is controlled by the idea.max.intellisense.filesize setting in idea.properties file.

The idea.properties file located in the bin directory of the MPS installation folder should not be edited. Instead of editing the original idea.properties file, create an idea.properties file in the following location, open it for editing and add the required properties:

For Windows: %USERPROFILE%\.%prod1%config
For *NIX: ~/.%prod1%/config
For macOS: ~/Library/Preferences/%prod1%/config

Note that the larger the file is, the slower its editor works and the higher overall system memory requirements are.

Do one of the following:
- Double-click the desired file in one of the tool windows.
- Select the desired file in one of the tool windows and press F4.
- Select the desired file in the one of the tool windows and choose Jump to Source on the context menu.
If the file type is registered, the file opens silently in MPS's editor.
If the file type is registered under the category Files opened in associated applications, it will be opened in its associated application, rather than in the MPS editor. By default, MPS suggests a number of such file types, for example .doc, .chm, or .pdf.

If the file type is unknown, MPS suggests to choose whether you want to register a new file type, or open such file in its associated application. Specify your choice in the Register New File Type Association dialog:

You can register the required file types in Settings/Preferences | Editor | File Types.

Opening external files

Do one of the following:

Choose File | Open on the main menu and select the desired file in the dialog box that opens.
Drag the required file from the Explorer (Windows), File Browser (Linux), or Finder and drop it to the editor. The file opens for editing in a new tab.

Reopening files

To reopen a file

To open a recently opened file, choose View | Recent Files on the main menu or press Ctrl+E. Then select the desired file from the Recent Files popup, that opens.
To open a recently updated file, on the main menu, choose View | Recently Changed Files or press N/A. Then select the desired file from the Recently Edited Files popup, that opens.

Opening files in a separate window

To open a file in a separate MPS window
