Am having trouble with an online backup service that supposedly fails because it is finding I have some folders with an excessive number (in the millions) of small files  Need a disk utility that will help me find folder with large numbers of included files.  Most utilities can easily find the largest folder but am looking more specifically to find the folders with the Largest Number of files.  Any help/advice would be appreciated.  Thank you!

How can I visualize which folders and files are taking up all of the space on my hard drive?  I'm getting some conflicting reports on the size of hard drive contents. Namely what is and isn't there and what folders are actually using the space.   I need to know which of the files or folders the culprits behind all this hidden bloat. Also there should be a print option to get it on paper.

If I have a number of directories, named, for example 10001 through 10025 is there any reason to use ls 1*/foo vs. ls 100??/foo?  I have a lot more than 25 of them, so I mostly curious if there's any differences in speed.  I know the difference in use between the two, that the asterisk will match longer file names, like 10001.backup. But let's say I don't have any files that don't follow my conventions. Is there any behind-the-scenes differences?

Is there a way to quickly check the amount of free / used disk space in Ubuntu?  I would assume you could right click on 'file system' in the file browser and choose 'properties' or something but there is no such option.

I'd like to copy files from one external drive to a network connected drive. I want to make sure that there are no errors.  I know of MD5 hash files that I see for large single files that are download from the internet. I also know that I can use the terminal to 'diff' the two sets of files.  However, I'm looking for a piece of software that could confirm that all the files in the file structure have been copied by the finder completely, or a piece of software that would do the copying for me and confirm that all the bits are exactly the same.  The files are video related - and are often over a TB in size (not in one file - complex multi-folder nested files)  I'm fine if there is a terminal command that can do the copy and compare for me as well. (although being able to see the amount of time left on a copy is a very nice feature... additionally, I want to make sure I get ALL of the file - resource forks and all)

I have seen some highly compressed files around, such as 700MB of data compressed to around 30-50MB.  But how do you get such compressed files? I have tried using software like WinRAR and 7Zip but have never achieved such high compression.  What are the techniques/software that allow you to compress files so well?  (P.S. I'm using Windows XP)

I need to rename a bunch of files in order to fix their sort order, therefore I need to be able to do a sort of "find and replace" so I can replace chunks of the filenames at a time.  What tools should I use? I prefer GUI but a command line tool recommendation would also be fine.

Does anybody have a snippet of Java that can return the newest file in a directory (or knowledge of a library that simplifies this sort of thing)?

Just discovered I have gotten a FOUND.000 folder on my usb drive. I guess from running chkdsk once. It has three files in it:   FILE0000.CHK FILE0001.CHK FILE0002.CHK   What exactly can I do with these files? What are my options? Are they lost files? Are they garbage? Can I use them for anything at all? Or will I just have to delete them?

A few nights ago I have created a backup of my data on an external 500 GB NTFS USB hard drive.  I have then formatted my computer, reinstalled Ubuntu and started transferring back the data from the external HDD.  Unfortunately some files have became corrupted and Ubuntu is unable to copy them over. The same issue happens if I login using Windows 7.  Disk Utility detects with SMART that there are "a few bad sectors".  Some of files are perfectly intact, but other files cannot be accessed (nor read, copied...) although they are displayed within nautilus and show the correct file size.  Is there anything I can do to recover this data? I have thought of using TestDisk but this utility seems more useful for repairing lost partitions or deleted files.  I have also thought of using ddrescue so I could at least have a low level copy of the disk but I am not sure what use to make of it in order to recover the data!!!

Microsoft technet states that document libraries have a file limit of 30 million items:    In practice, numerous features seem to break once there are more than 5000 items in a Document library - not just in the initial directory listing - but as a recursive total. For example, you may be able to list folders, but setting permissions or deleting files is met with errors.  Are there any configuration options or optimizations that can be used to relax these limits?  A workaround would be to split folders into separate document libraries, but in our case, with over 5 million files, this would result in a minimum of 1000, 5000 file document libraries and likely many more. At that point we're likely shifting the problem into the library view.    A major showstopper is the effect this has on Sharing - a user trying to share a folder with more than 5000 aggregate items simply fails. I'm investigating the effect (if any) the resource throttling suggestion below has on this.

I am a Windows user and coming from Windows with all the indexing and eternal wait times when searching for files, I find it surprising how fast does locate work or the autocompletion (that I know) work in linux.  Is there any indexing being done in the background or how is this achieved? I still have a pretty clean installation, so maybe this goes bad with time, but in Windows the moment you want to search on a folder which is not indexed you have to wait for some seconds.

I want to see how many files are in subdirectories to find out where all the inode usage is on the system. Kind of like I would do this for space usage  du -sh /*   which will give me the space used in the directories off of root, but in this case I want the number of files, not the size.

I have a directory that contains thousands of files, some of them are hidden.  The command ls -a list all files, including hidden ones, but I need just to list hidden files.  What command should I use?

I have always had problems with my windows directory's growing to a huge size.  It started with windows 95 then 98 then 2000 and xp.  Windows 7 however is absolutely huge.  The windows folder itself with out program files is 21.4 gigs...add the program files and other windows files and it is a whopping 32 gigs.  My question is why is it so large and what can I do about it.  At the rate this is going I will be out of space in now time.

I'm able to find processes using top or ps. That's no problem.  Sometimes I find that some processes are taking up a lot of memory or cpu and I'm trying to identify what the root program is.  For instance, the process sort sometimes just ends up taking 2-3 gigs of memory over like 4 hours. I'd like to know what program initiated the sort process so I can try and fix it.

I recently noticed that one of my external hard drive seems to be missing a lot of space. It was recommended that I try WinDirStat, as it could help identify how much space each file was taking up. This is the result:     As you can see, there is about 244.7GB "unknown" usage.  Doing a bit of research online, the most common suggestion was (a) Recycle Bin and (b) System Volume Information.  (a) As you can see, empty. To double check, I ran Disk Cleanup. It confirmed that it was empty. (Note that a new file appeared by the time I took this screenshot, but it's only 129 Bytes.)  (b) Harder to tell. However, according to various forums, the most common reason for System Volume Information to grow large is due to System Restore Files. I had a look, and it is definitely turned off for this drive, as seen here:     What else could be causing this issue? It is an enormous amount of storage to have gone missing!

I've just discovered UltraSearch and was blown away by its file and folder search speed. It's instantaneous. And doesn't use any indexing service. It simply uses the , which already stores all the filenames on the NTFS partition.  The question is, why isn't this capability way more popular among file managers, and Windows Explorer Search (Win+F) to begin with?
