Downloaded for exfat format reads on my pixel 3. Wanted to test before buying the full application, and I'm glad I did. Card wasn't able to be read at all. I ended up downloading the trial app from paragon instead and it works there without any issues. Maybe my review can help the devs figure this one out. Steps to reproduce : 1. Download this trial app 2. Insert exfat card via usbc card reader 3. Open with this app 4. App says card can't be read, also crashes

Such a poor way to offer a trial of your app. If copy/paste isn't available in the trial, why would I pay for the pro. Let me try all the features for a certain period of time, then I'll pay if they work. And you can't even copy from internal storage to the OTG device!

I would buy this app if it had an option to skip existing files when copying from usb to sd card. I backup my camera photos daily and don't want to keep copying over same files every time.

Does not work on my Pixel with Android 10. It's really frustrating that Google does not support exFAT file systems.

only for viewing or copying. can't delete. trash for that. ad is annoying and messes up long press so you have to view more than once

I've only tried the trial so far, but it seems like it will be better than the paragon alternative.

better than paragon. The most reliable exfat mounter.

Stupid App

Ric. M. Jun 8, 2018     

It seemed a difficult task - to mount an NTFS device and see what was on it. Plenty of apps pushing plenty of noisy adverts, and either failing to see the device or failing to understand NTFS. But not this. This app is short, sweet, to the point, and does exactly what it says on the tin. Thank you!

Err. l. Jul 24, 2018     

Simple to use, dosen't have many advertisments and it's the first one that was actually able to read a file from my usb drive, even though the company looks a little shady it works great for me.

yud. g. Jan 18, 2018     

Good, all work as description, good for read flashdisk or hard drive more than 32 GB cause the system file used exfat or ntfs..., this will become great app if could write to in exfat file system..., keep a good work devs...

Great app for using external HDD formatted in NTFS or EXFAT
