#1. Clean up system junk files and unnecessary large files from the C drive

When cleaning your C drive, you may think of deleting unnecessary large files. However, doing it manually can be complicated. Relying on a professional disk cleanup solution to efficiently locate and delete junk files and unnecessary large files from the system drive is a better option.

The System Cleanup feature of Todo PCTrans Technician can help all levels of Windows Server users clean up junk files on the C drive easily and effectively.

System Cleanup:

Step 1: Open Todo PCTrans on your computer. Click “System Cleanup” and then hit the “Scan” button.

Step 2: Once the scan is complete, a list of junk files will be displayed. Choose the ones you want to get rid of. Be careful not to delete anything that might affect your computer or software's performance.

Click the "Clean Up" button and confirm the cleanup. You can use this feature regularly to free up disk space.

Clean up large files:

Step 1: Open the Todo PCTrans tool on your computer. Click "Big File Cleaner" and then hit the "Start" button to proceed. (It supports moving or deleting large files to free up more disk space. You can also try moving default folders to another drive.)

Step 2: Select the hard drive you want to scan.

Step 3: After the scan is complete, all files larger than 20 MB will be listed. Select the ones you don't need. Be careful not to delete anything that might affect your computer or software from running properly. After the scan, you can also view the deletion suggestions in "Large File Clean Up."

Click “Delete” to confirm the deletion. You can use this tool periodically to free up space by deleting large, unnecessary files. If you have more space on another drive, select “Move” instead to move the file.

#2. Move the program to another drive from the C drive

In addition to system junk files, large programs and games that you install can also take up a lot of space on your C drive.

To make the most of your C drive storage space, you can move installed programs and software from the C drive to another drive on your Windows Server computer. The App Migration feature of Todo PCTrans is just what you need for this purpose.

2. Click the triangle icon and select another disk on your computer as the target location, then click “Transfer” to start the transferring process.

Select the programs you want to transfer

Step 3: Complete the transfer

Wait patiently for the conversion process to complete, and then click “OK” to confirm.

When done, if necessary, you can restart your PC. This will preserve all changes made to the computer and allow you to run the program from another hard drive without having to reinstall it.

#3. Uninstall Program

Click “Disk Cleanup” and select the items on your C: drive that you want to delete, such as downloaded program files, temporary internet files, and the Recycle Bin.
