Handle modified without checkout files
If you are going to modify or delete a file under Perforce version control, the read-only status of such file should be removed. PyCharm takes care of automatically making files writable. However, you can change read-only status manually, which may happen in a number of ways; for example:
With the Clear Read-Only Status option enabled, you make a file writable using file system.
When a read-only file is opened in the editor, you double-click lock icon
in the status bar.You remove read-only attribute externally, using file properties.
In these cases, the file gets status Modified without checkout and appears in the Local Changes view .
To resolve 'modified without checkout' files
In the Local Changes view , expand Modified without Checkout node, and select the desired file.
From the context menu of the file, choose Check Out. The file becomes writable, and moves to the active changelist.
