You can use the Source Control Explorer to view all of the files that you have checked out and need to check in.
How to View Files That You Have Checked Out
- Select View > Source Control Explorer. The Source Control Explorer opens.
-
From the drop-down or the Home pane, select Pending Changes.
The Pending Changes pane opens. Files that you have changed appear in the Included Changes or Excluded Changes section (depending on whether you are going to include or exclude them in your next check-in).
-
Take note of the file's status. The status is written in brackets next to the file name (e.g., edit, add).
Note You can click the refresh navigation button 
in the Source Control Explorer to make sure you have the most recent status for each file. Another option is that you can use a feature to automatically ping the source control repository periodically, thus refreshing this information frequently. However, you may experience slower performance with this automatic status update option set.
Note When you check out a file from source control, you are actually checking out the file's corresponding XLF file. You will see the XLF file if you open the Source Control Explorer. This is because you need the XLF file available in order to make changes, view the file's history, or view differences.
Note When you modify a file in source control, you may sometimes see a SKL file alongside the XLF and original files. This skeleton file is a placeholder file. Be sure to check in all three associated files together. Checking in just the SKL file may result in errors.
