Hi Ka4nmx,
It depends on the size of the disk space of the computer.

There's no practical limit on the combined sizes of all the files in a folder, though there may be limits on the number of files in a folder. More importantly, there are limits on individual file size that depend on what filesystem you're using on your hard disk. (The "filesystem" is nothing more than the specification of exactly how files are store on disk.)
Windows 7 supports NTFS file system. NTFS, or "New Technology File System" introduced with Windows NT, is a completely redesigned file system.
◦Maximum disk size: 256 terabytes
◦Maximum file size: 256 terabytes
◦Maximum number of files on disk: 4,294,967,295
◦Maximum number of files in a single folder: 4,294,967,295
Note that when I say "disk" above, I'm really talking about "logical" disks, not necessarily physical. No one makes a 256 terabyte disk drive, but using NTFS you can treat an array of disk drives as a single logical disk. Presumably if you have enough of them, you can build a huge logical drive.
