So, has anyone else been noticing their C drive getting absolutely devoured by WPS Office lately? It’s a huge pain point right now. A ton of users are complaining that this office suite quietly hoards massive amounts of space on their system drive, making their computers crawl to a halt and seriously messing with their work flow.
And honestly, figuring out how to clean up that mess or stop it from hogging your C drive in the first place feels like guessing in the dark for most people.
Last June 23rd, I (NUPIAO) dug into this and contacted WPS customer support directly. Here’s the deal: They told me that while average users might not run into this often, there’s definitely some confusion around how caching works. Basically, they explained that cache is essential for the software to run smoothly—it speeds up responses, optimizes loading times, and makes using cloud documents feel way more fluid. In short, it’s supposed to improve your overall experience.
The rep also clarified that these cached files aren’t permanent; the system automatically clears them out regularly, so it shouldn’t tank your device’s performance or risk your privacy.
But here’s the kicker: Later that same day, Jinsan Office (the parent company behind WPS) issued a formal statement confirming they’d set up a special task force to investigate. They didn’t just explain the “why,” they gave us concrete solutions too.
Here’s the good news: Everything needed to fix this is 100% free. You don’t need a premium membership to do any of this. Here are the two main fixes:
- Change Your Storage Path: You can easily move where WPS saves its backups and cache. Just head into your WPS Cloud settings or go to File > Backup & Recovery > Backup Center. From there, you can redirect those folders to any other drive (like D: or E:) instead of leaving them stuck on C.
- Manually Clear Local Cache: You can go ahead and delete local copies yourself. Don’t worry—this won’t touch the files safely stored in your cloud account.
So why does this happen? WPS admits that to let you access the same file seamlessly across phones and PCs without re-downloading everything every time, they keep a local copy of your cloud docs. While this is standard practice for cloud drives, they acknowledge that having this data default to the C drive—and the lack of clear visibility into how much space it’s taking—is a design flaw that has frustrated many users, especially heavy cloud document users.
This isn’t even the first time we’ve seen this issue. Back in August 2024, users were already reporting that WPS was forcing their cloud storage paths back to the C drive, overriding manual changes made to the D drive. At the time, the community was flooded with similar complaints.
For context, WPS Office remains the flagship product developed and operated entirely by Jinsan Office, which listed on the Shanghai Stock Exchange back in November 2019.
Looking at the financials, things are booming. In Q1 2026, Jinsan Office reported revenue of approximately 1.613 billion yuan, a 23.95% jump from the previous year. Their total profit surged an impressive 473.92% to about 2.406 billion yuan, with net profit attributable to shareholders hitting 2.195 billion yuan. Even after adjustments, the net profit grew by over 32%.
Specifically, WPS personal business brought in 975 million yuan, up 13.8%. By the end of March 2026, global monthly active devices for WPS Office hit 672 million, with 328 million coming from PC users alone—a 9.08% increase.
Interestingly, NUPIAO noticed that the massive spike in Q1 profits was largely driven by investment income rather than just software sales, as the company noted significant returns from various external funds.
Looking back at last year, revenue stood at 5.929 billion yuan (up 15.78%), with net profit reaching 1.836 billion yuan. As of the close on June 23rd, shares of Jinsan Office were trading at 215.43 yuan, dipping slightly by 5.07% that day.
