Hardware :: How To Delete Files From USB Flash Drive In OS X
Nov 9, 2007
I don't know how to delete truly files from my flash drive. Whenever I press cmd+backspace or simply drag file to trash, it doesn't delete fully, i.e., space available doesn't increase on flash drive, the icon just disappears. When I plug it in using Windows, I can see .Trash and .Spotlight<something> folders which are hidden. In .Trash I see my deleted files, but how the heck can I really delete them off my flash drive? I often just copy all my content to hard drive, format flash drive and then copy back my content.

I hope my question has not been answerd yet, don�t want to bother anyone:
I use a USB-Flash Drive between my Mac and the PC�s at University. I can�t seem to delete the "Recycler"-file from the USB-Driver.
It wouldnt be a problem if just the file was visible, but after deleting all files and docs I still don�t have the free space I need.

I have a 1GB flash drive..of which i've placed some iTunes formatted home movies in to hand to my dad who has a Windows XP laptop.
When this flash drive is connected to his laptop and I discover the flash drive on XP, and try to open it...nothing happens. Nothing opens. At best it says that in order to view the files in the flash drive that Windows XP needs to reformat the flash drive, but in the process it states that it will have to erase all content and data to do so..
So now i'm wondering how can I transfer these movie files from my MBP to his Windows XP laptop.?
I've only tried this on flash drives and really hope it wouldn't be the same situation if I used my external hard drive instead; as in connecting my external HD which had a ton more home movies, connect it to his laptop and hopefully it showing up... My external HD isn't running Time Machine or anything like that, it's just a clean External HD where I throw in a lot of home movies...

Title says it all. Basically, I reformatted my new flash drive to MS-DOS (which I think/suspect it was already) and files copied onto the flash drive become much larger. For example, a 275 megabyte folder full of images turned into a 425 megabyte folder-even when dragged off the flash drive.
What could cause this? I do suspect that it's a labeling error, as the file doesn't act like it's gained size.

I went to use my flash drive to open some old files (which were created on a pc, Word) to see if I wanted to delete them, opened several files with Word using Windows for Mac, closed out the files, went to reopen them and couldn't. The size of the files went down to zero KB after opening. I had tried to move several to the trash but I got an "error -43" code. I can't figure out why this is happening. No idea where to start.

I have a sandisk cruzer and i finally decided to uninstall the u3 software, so i copied all my files to a folder on my desktop and then used the removal tool. now i can't get some of the files back on. all of the loose files that i had on the flash drives went back, but i cannot get any of the folders that i had on my flashdrive back on. i used to get a -36 error, but after i reformatted my flash drive, now i get "The operation can�t be completed because you don�t have permission to access some of the items."

I just transfered all my files from Iomega Zip drivers to Mac compatible HP Flash drive. Now I can't open any of those files on HP Flash drive. Some of the files have even disappeared. Is there something I'm suppose to do with Flash drive to open files. If I can't open any of my files on HP Flash drive, is there any program I can purchase to retrieve files on Zip Drive?

I have a 24" intel imac from 2 years ago and it has USB2 ports on the back right, well if I plug in a flash drive and take files from the drive to the computers they transfer at USB2 speeds. But when I go the other day and copy from the mac to the USB drive it's slow as hell. Like USB1 or worse speeds. It's not like that on my PC at work which has similar specs to the IMac.

I have 2 Ibooks: one has OSX and the other is on the highest version of the old OS9. Something odd happened the other day with a new USB flash drive I started using. I was transfering files (word docs) onto a flash drive. When I inserted the flash drive in the old iBook, each file (and document) showed the date Dec 9, even though the docs were from Dec. 16. When I inserted the flash drive in the newer iBook, it showed the correct dates for each doc. I tried this back and forth, and found the same thing. Yet, all the dates are correct on everything on my hard drive on the old iBook. It only is a problem with this new flash drive I'm using. It never happened before.

I have a flash drive that I use a good bit, but recently it's started doing this thing where it won't eject. Even force ejects hang and I literally have to restart the computer to get the message to go away.
It also has issues deleting files. Perfect example, I just plugged it in, dragged one file to the trash, didn't do anything else, and when I try to empty the trash it says that file is in use when it definitely is not. Then, giving up on that I try to eject the drive and it won't.
I'd say it won't eject about 3/4 of the time. Other drives are fine, so it's not something I'm doing, and it does it on every computer I try, so it's not just my computer in particular.Any ideas what might be causing this?

When copying files to a flash drive it takes 10X longer than it used to. It sometimes takes an hour instead of a few minutes.Â

I'm new to Mac.
I copied some directories/files from my PC to a LaCie external drive. I then copied them from the drive to the iMac.
I tried to delete, e.g., drag to Trash, them from the external drive while connected to the iMac. It didn't work. I tried a mouse right click, but no delete on Menu. Is there a way to delete files on the iMac? I ended up connecting the drive to the PC, & deleting the files, but I'd like to be able to do the same from the iMac.

For some reason, when I try to delete files from my flash drive, the file disappears but I don't get any space back on the flash drive. This is ruining my 32 GB flash drive.

I have an external hard drive that I use as my "back-up" of old jobs. I then burn my jobs to a dvd and then delete the files I burned. Is it possible to just delete the files from the external hd and not my computer?

I am recieving an error message when I try to copy new files (images, documents) to mac from flash drive/SD card. The message is saying "operation cannot be completed because an item already exists with that name." They are brand new therefore not the same name? I cannot even put them in a brand new folder..

I had just purchased a Lacie 500GB xternal drive for my G5, I also have another xternal drive hooked up which is a Western Digital. I copied everything , music video files ect... onto the Lacie drive to clean up the WD drive, now when I went to clean up the new Lacie drive the files I deleted are gone but it is not freeing up any space. I went to disk utilities and re-formatted but it wiped it clean, is there such a way to delete a few files here and there and gain the space they were taking up without going this route?

Basically I just got myself the latest MacBook as an upgrade from an old laptop. With my old laptop I had no problems what so ever when using my external hard drive. To delete any files I didn't want I would just right click and press the delete option. However, when connected to my new Mac, there is no such option when right clicking on a file. I've tried dragging the file to a recycling bin but I get a message from the finder saying this file can't be deleted. I've tried moving the file out of my hard drive which worked and then deleting it which was fine but the file remained in the external hard drive as I'd only created a copy. I can't figure out how to delete files I don't want. Deleting everything on the hard drive is out of the question.

I've been backing up my MacBook Pro on an external portable hard drive. I need to delete some but not all the files from that portable hard drive permanently. When I highlight them and click to move them to Trash I get a message telling me this cannot be done because they are Read Only files? How do I go about it. I am required by work to delete them off this hard drive. Do I have to reformat the hard drive? If so how do I go about it?

I have a couple of FW drives hooked up to my iMac and I just discovered I can't trash anything from them. Actually, ever since upgrading to Lion I've been having all sorts of permission issues, but that's another discussion. In this case I've gone to the info windows for these drives and I have only read premission and I can't seem to change it. I've done all the usual things to do so but it remains stuck on "read only." I'm regularly repairing permissions so I don't see that working, tho I haven't tried trashing anything from these drives in a while so I don't know how long it's been this way. Â

I have set up an external drive as above.The drive is to be used to archive large amounts of uncommonly used data (not a backup) and then is backed up to crashplan+ off-site. The drive came formatted as FAT32 (I believe.) As we still have one PC and all individual files are smaller than 4Gb, I set up the archive drive as formated out of the box.
Data was written to the drive without issue, backed upi off-site with no issue and accessed a couple times.
The issue came when recently upgraded some itunes albums. These albums had been previously removed from the library and from the computer and stored in the archive drive. These albums were upgraded and redownloaded from apple generating a copy of the album data, but in a superior format (no-drm, greater sampling rate.) This made the archived files obsolete and generated a risk of mixing versions. I decided to delete the obsolete files from archive.
When I attempted to do this by selecting, right-clicking and chosing "move to trash" I was prompted that this was not a "undo-able" action, suggesting that while I was selecting "move to trash," the action would not generate a copy in the trash.Next I was prompted to enter my user and PW. The only user and PW combo that would not cause the dialog to "shake it's head" at me, was my computer user-specific password.The network or drive associated user and PW combos would not take When I entered my computer user and PW, it was accepted, but a dialog labeled "Trash" popped up with small font, reading "The operation can't be completed because you don't have permission to access some of the items."
Trying to delete only a random selection of one or two files would not work.I checked the drive permissions and was only able to see "You have custom access."This is not modifiable. I attempted to alter my access permissions from the router, but made no headway.
Assuming, with little data, that the FAT32 was perhaps at issue I unmounted the network drive, connected it by USB and reformated as above. After formating, I tried the same procedure with no change in outcome.I am nearly 100% sure that when the drive was connected by usb, I could delete to my heart's content, but not when it is connected via network. I will note that the drive is accessed by first connecting to the router, which the mac sees as a "PC." This access can be controlled, but can be set to anon. When I connect I see two identically named folders.One is a sharepoint folder and one is a volume. They access the same data. Deleting thorugh either route has identical outcomes.

Tried unlocking and allowing myself to read and write. Nope. Tried holding down the option key. Nope.
This drive is no longer being used by time machine and I want to delete some files on it. Is there a way to do it without wiping the entire drive?

I want to create a simple flash movie (I don't yet own or know how to use Adobe Flash). Pretty flowers in the background, inspirational music, passages from the Bible or something fading in an out... you know the schtick. Maybe convert it to a screen saver.

Here is the back ground information of this situation. I have a IMAC 21 inch 500GB Hard drive 4 GB RAM, which is up to date with OS X Ver 10.7.3. So my wife loves to stream her favorite USA TV shows via the Internet, considering we are stationed overseas. She pulled me away from the NBA playoffs because she kept getting this error of start up disk full delete files (or something to that effect.) So last week, I deleted about 40GB of old shows that we downloaded and various other files and pictures. Not even four days later the Hard drive is full again, and I think it is from my wife's streaming habit. I went to "About This IMAC", to find out where the memory was being used from and its 377 GB used in a "OTHER", and the rest being utilized from APPS, MUSIC, PICTURES, etc. So next I cleared the history and deleted the cache files and reset safari on both our log in profiles, then logged out and restarted the computer, which did not minimize the Hard drive memory being occupied. Where are those streaming files getting saved specifically, for maybe a manual delete?Â

I've looked at some other posts that have gone over how to move files to an external drive, and they all say to use command while moving. I understand this copies the file and deletes the original, but when you make a copy and delete the original, you lose some of the original data, such as creation date, etc... This makes storage and organization more complicated than it has to be.
