Have you encountered a problem where WinRAR fails to extract files and displays an error saying “Write error in the file xx. There is not enough space on the disk”? You're in the right place. This guide provides several effective solutions for resolving this issue when WinRAR reports insufficient disk space.

WinRAR Write Error: Not Enough Space on the Disk

WinRAR is a widely used tool for compressing and decompressing files, supporting formats like ZIP, RAR, ISO, Z, 7-Zip, TAR, UUE, and more. It works well with Windows 10 and 11.

Despite its reliability, users sometimes face an error stating that there’s not enough space on the disk when trying to extract files. The exact message reads: “Write error in the file xx. There is not enough space on the disk”.

This occurs when the target drive doesn’t have enough available space to store the extracted data. Additionally, if the system's temporary folder lacks sufficient storage, the same error may appear.

By default, WinRAR uses a temporary folder located at C:\Users\\AppData\Local\Temp during extraction. Once extraction completes, these temporary files are deleted. However, if the C drive is full, the Temp folder can't function properly, resulting in the "not enough space" error.

The good news is that there are multiple ways to resolve this issue.

Fix 1: Use MiniTool System Booster

To fix the WinRAR error related to insufficient space, first try freeing up disk space. A reliable way to do this is by using MiniTool System Booster, a dedicated PC cleaning and optimization tool. It helps remove unnecessary files, defragment hard drives, and uninstall unused programs to free up storage.

Follow these steps:

Step 1: Download, install, and launch MiniTool System Booster.

Step 2: Navigate to the Performance page, select Deepclean, and click START CLEAN.

Step 3: Allow the program to perform the following cleanup tasks:

Internet Cleanup: Clear internet-related junk files.

Windows Cleanup: Remove logs, temp files, error reports, and empty the Recycle Bin.

Program Accelerator: Defragment your HDD (not recommended for SSDs).

Step 4: If installed apps are consuming significant space, go to Toolbox > Advanced Uninstaller, locate unwanted applications, and click UNINSTALL to remove them.

Fix 2: Run Disk Cleanup

You can also use the built-in Disk Cleanup utility to delete temporary and system files, which may free up several gigabytes of space.

Here’s how:

Step 1: Open Windows Search, type Disk Cleanup, and press Enter.

Step 2: Choose the C drive as the target for cleanup.

Step 3: Select all items you want to delete and click OK > Delete Files.

Step 4: Click Clean up system files, choose what to remove, and proceed with the task.

Fix 3: Change the Temporary File Location in WinRAR

As previously mentioned, WinRAR stores intermediate files in a temporary folder. If that folder resides on a nearly full drive, the extraction process will fail. Changing the location of the temporary folder can quickly resolve this.

Step 1: Launch the WinRAR application.

Step 2: Go to Options > Settings, then switch to the Paths tab.

Step 3: In the Folder or temporary files field, click Browse to pick a new directory.

Step 4: Deselect the option Use only for removable disks, then click OK to confirm changes.

Fix 4: Extract Files to a Different Drive

Another approach is to extract files directly to a different drive with ample space.

Here’s how:

Step 1: Right-click the archive file and select Extract files.

Step 2: In the WinRAR window under the General tab, click Display, expand This PC, and choose another drive as the destination.

Step 3: Confirm the action by clicking OK.

Fix 5: Extend C Drive or Upgrade to a Larger Hard Drive

If the issue persists due to limited space on the C drive, consider extending the partition using MiniTool Partition Wizard. Alternatively, if the entire disk is too small, upgrade to a larger one.

Use MiniTool ShadowMaker to clone your current disk to a new one without reinstalling the OS. After cloning, replace the old drive with the new one. For detailed instructions, refer to our hard drive cloning guide.
